Smooth scroll to element - jQuery. Scrolling to an element using jQuery. Smooth transition when clicking on a button Jquery scroll page to element

Over the past few years, the popularity of one-page (scrolling) sites has seriously increased. Although this type of site is not for everyone, it is still useful to know how they work. Today I'll show you how to create a simple one-page (scrolling) website using jQuery.

Before we start, you can watch the Demo.

Well, let's get started...

We will create the following:

HTML

The markup (HTML) of the page will be extremely simple.

First, let's create the navigation.

  • Paragraph 1
  • Paragraph 2
  • Paragraph 3
  • Paragraph 4
  • Paragraph 5

What we've done is that the nav element has a width of 100%, meaning its width will be equal to the width of its parent element. For nav, the position property is set to fixed , so when scrolling the page, the nav element will always be in front of the user's eyes. To create the navigation, we placed the ul tag in the nav tag.

Advantages:

  • If the user has javascript disabled, the links still work.
  • Using jQuery we will read the href attribute from each link.

    • Now that we've created a simple navigation bar, we can move on to the main content of the page.

    Lorem ipsum dolor sit amet, consectetur adipiscing elit...

    In ut sapien sem, a convallis odio. Aenean consequat ornare egestas...

    Donec sodales diam et libero ultrices ornare...

    Phasellus dolor sem, pharetra nec scelerisque sit amet, consequat quis dolor...

    Proin varius pellentesque velit, at consequat risus hendrerit quis...

    As you can see, the markup is extremely simple. It consists of a content block that contains paragraphs (p). Each paragraph has its own id associated with a link in our navigation.

    CSS

    Before you start with the CSS, don't forget to include the . It eliminates problems associated with cross-browser incompatibility and allows you to work without wondering whether the site will look the same in all modern browsers.

    Let's start with styling the main content of the page, which is very simple.

    Body ( font-family: arial; font-size: 15px; line-height: 25px; color: #515151; background: #fdfdfd; ) #content ( width: 500px; margin: 0 auto; padding-top: 40px; height : 2000px; ) #content p ( margin-bottom: 25px; )

    In the body we define the text and background colors; The content block is 500px wide and centered. The padding-top value for the content block is 40px - this is done so that the navigation does not block the top 40px of the content. The height is 2000px to fit the content and show scrolling. Although, as a rule, this is not necessary. Each paragraph has a margin-bottom property of 25px to help you understand where one paragraph ends and another begins.

    Now let's move on to navigation:

    Nav ( width: 100%; position: fixed; height: 40px; background: white; border: 1px solid #CACACA; border-top: none; -webkit-box-shadow: 0px 0px 3px 1px #ebebeb; -moz-box -shadow: 0px 0px 3px 1px #ebebeb; box-shadow: 0px 0px 3px 1px #ebebeb; ) nav ul ( width: 750px; margin: 0 auto; ) nav ul li( float: left; width: 150px; text-align : center; ) nav ul li a ( line-height: 40px; font-size: 16px; text-decoration: none; color: #515151; border-bottom: 1px dotted #515151; ) nav ul li a:hover( color : #000;

    To ensure that the nav takes up the entire width of the browser, its width value is 100% . To keep the nav on the monitor screen when scrolling, it has a position:fixed declaration. The height is 40px, which is quite normal for a horizontal top menu. A simple style has been used to give a cute look. ul is centered and 750px wide to give each link enough space. Each li is designed to float, so all links are on the same line. Finally, the links are also given a simple style.

    jQuery

    Here's how it will work: when you click on a navigation link, it will scroll to the paragraph that the link points to.

    As always, let's start with the document.ready function

    $(document).ready(function())( ));

    Now, before moving on to the click function, let's write a scrollToDiv function that will scroll to the block we have selected. There will be 2 parameters - the element to which scrolling is carried out and the height of the navigation bar at the top of the page.

    Function scrollToDiv(element,navheight)( )

    Now we describe three variables; we will need them for accurate scrolling.

    Function scrollToDiv(element,navheight)( var offset = element.offset(); var offsetTop = offset.top; var totalScroll = offsetTop-navheight; )

    The offset variable is the element's offset. This is used by the offsetTop variable to retrieve the value of top . As a result, we get the distance from the top of the page to the element. The totalScroll variable is responsible for the distance the browser needs to scroll the page. Without the top navigation bar, the scrolling amount will be equal to the offsetTop value. However, when calculating the totalScroll variable, we need to remember that our navbar blocks the top 40px of content. The navheight parameter will help us here.

    Finally, let's scroll the page:

    $("body,html").animate(( scrollTop: totalScroll ), 500);

    The jQuery animate function will allow us to implement smooth scrolling to the desired location on the page. In this case, the animation takes 500 milliseconds.

    The scrollTop property allows you to set the amount by which you want to scroll the page (vertically).

    Here is the complete scrollToDiv function:

    Function scrollToDiv(element,navheight)( var offset = element.offset(); var offsetTop = offset.top; var totalScroll = offsetTop-navheight; $("body,html").animate(( scrollTop: totalScroll ), 500) ; )

    Let's move on to the click function.

    $("nav ul li a").click(function())( return false; ));

    This is just a skeleton of the click function. Declaring return false at the end will prevent the browser from following the link.

    Before you pass an element to a function, you need to find a name for it.

    Var el = $(this).attr("href"); var elWrapped = $(el);

    The el variable contains the value of the href attribute. For jQuery to use the el variable, it needs to be wrapped in elWrapped. The following jQuery code cannot execute:

    #paragraph1.offset();

    But it can do this:

    $("#paragraph1").offset();

    This is why the elWrapped variable is needed.

    Full click function:

    $("nav ul li a").click(function())( var el = $(this).attr("href"); var elWrapped = $(el); scrollToDiv(elWrapped,40); return false; ) );

    That's it - now we have a simple a page with links that, when clicked, scroll to the desired part of the page.



    scrolling jquery (21)

    I wrote a general purpose function that scrolls through a jQuery object, CSS selector, or numeric value.

    Usage example:

    // scroll to "#target-element": $.scrollTo("#target-element"); // scroll to 80 pixels above first element with class ".invalid": $.scrollTo(".invalid", -80); // scroll a container with id "#my-container" to 300 pixels from its top: $.scrollTo(300, 0, "slow", "#my-container");

    Function code:

    /** * Scrolls the container to the target position minus the offset * * @param target - the destination to scroll to, can be a jQuery object * jQuery selector, or numeric position * @param offset - the offset in pixels from the target position, e.g. * pass -80 to scroll to 80 pixels above the target * @param speed - the scroll speed in milliseconds, or one of the * strings "fast" or "slow". default: 500 * @param container - a jQuery object or selector for the container to * be scrolled. default: "html, body" */ jQuery.scrollTo = function (target, offset, speed, container) ( if (isNaN(target)) ( if (!(target instanceof jQuery)) target = $(target); target = parseInt(target.offset().top); container = container || "html, body"; if (!(container instanceof jQuery)) container = $(container) offset = offset | | 0; container.animate(( scrollTop: target + offset ), speed );

    I have this input element:

    Then I have other elements like other text inputs, text fields, etc.

    When the user clicks on this input with #subject , the page should scroll to the last element of the page with a nice animation. It should be a scroll down and not up.

    The last item on the page is the submit button with #submit:

    The animation should not be too fast and should be fluid.

    I'm running the latest version of jQuery. I prefer not to install any plugin but rather use the default jQuery functions to achieve this.

    When the user clicks on this input with #subject, the page should scroll to the last element of the page with a nice animation. It should be a scroll down and not up.

    The last element of the page is a submit button with #submit

    $("#subject").click(function() ( $("#submit").focus(); $("#subject").focus(); ));

    First scroll down to #submit then #submit the cursor on the input that was clicked, which simulates scrolling down and works in most browsers. It also doesn't require jQuery since it can be written in pure JavaScript.

    Could this way of using the focus function simulate the animation better, by chaining calls to focus . I haven't tested this theory, but it would look something like this:

    #F > * ( width: 100%; ) .. .. .. .. $("#child_N").click(function() ( $("#child_N").focus(); $("#child_N +1").focus(); .. $("#child_K").focus(); $("#child_N").focus(); ));

    jQuery(document).ready(function($) ( $("a").bind("click.smoothscroll",function (e) ( e.preventDefault(); var target = this.hash, $target = $( target); $("html, body").stop().animate(( "scrollTop": $target.offset().top-40 ), 900, "swing", function () ( window.location.hash = target; ));

    • Section 1
    • Section 2
    • Section 3

    Animations:

    // slide to top of the page $(".up").click(function () ( $("html, body").animate(( scrollTop: 0 ), 600); return false; )); // slide page to anchor $(".menutop b").click(function())( //event.preventDefault(); $("html, body").animate(( scrollTop: $($(this). attr("href")).offset().top ), 600 return false )); // Scroll to class, div $("#button").click(function() ( $("html, body").animate(( scrollTop: $("#target-element").offset().top ), 1000); // div background animate $(window).scroll(function () ( var x = $(this).scrollTop(); // freezze div background $(".banner0").css("background-position", " 0px " + x +"px"); // from left to right $(".banner0").css("background-position", x+"px " +"0px"); // from right to left $( ".banner0").css("background-position", -x+"px " +"0px"); // from bottom to top $("#skills").css("background-position", "0px " + -x + "px"); // move background from top to bottom $(".skills1").css("background-position", "0% " + parseInt(-x / 1) + "px" + ", 0% " + parseInt(-x / 1) + "px, center top"); // Show hide mtop menu if (x > 100) ( $(".menu").addClass("menushow"); $(".menu").fadeIn("slow"); $(".menu").animate((opacity: 0.75), 500); else ( $(".menu").removeClass("menushow" ); $(".menu").animate((opacity: 1), 500 )); // progres bar animation simple $(".bar1").each(function(i) ( var width = $(this).data("width"); $(this).animate(("width" : width + "%" ), 900, function())( // Animation complete ));

    This is my approach abstracting IDs and href"s using a universal class selector

    $(function() ( // Generic selector to be used anywhere $(".js-scroll-to").click(function(e) ( // Get the href dynamically var destination = $(this).attr(" href"); // Prevent href=“#” link from changing the URL hash (optional) e.preventDefault(); // Animate scroll to destination $("html, body").animate(( scrollTop: $(destination ).offset().top ), 500 ));

    • Item 1
    • Item 2
    • Item 3

    Using this simple script

    If($(window.location.hash).length > 0)( $("html, body").animate(( scrollTop: $(window.location.hash).offset().top), 1000); )

    What I would do in sorting is that if a hash tag is detected in the URL, scrollTo animates its ID. If the hash tag is not found, then ignore the script.

    Var scrollTo = function($parent, $element) ( var topDiff = $element.position().top - $parent.position().top; $parent.animate(( scrollTop: topDiff ), 100); );

    If you don't care much about the smooth scrolling effect and are just interested in scrolling to a specific element, you don't need some jQuery function to do this. Javascript has your thing:

    So all you have to do is: $("selector").get(0).scrollIntoView();

    Get(0) is used because we want to get the JavaScript DOM element, not the JQuery DOM element.

    If you're only handling scrolling to an input element, you can use focus() . For example, if you want to scroll to the first visible input:

    $(":input:visible").first().focus();

    Or the first visible entry into the container with class .error:

    $(".error:input:visible").first().focus();

    Thanks to Tricia Ball for this!

    Easy way to achieve page scroll for target div id

    Var targetOffset = $("#divID").offset().top; $("html, body").animate((scrollTop: targetOffset), 1000);

    $("html, body").animate(...) is not for me on iphone, chrome browser browser.

    I needed to customize the target content element on the page.

    $("#Content"). Animate (...)

    This is what I ended up with

    If (navigator.userAgent.match(/(iPod|iPhone|iPad|Android)/)) ( $("#content").animate(( scrollTop: $("#elementtoScrollToID").offset().top ), "slow"); ) else( $("html, body").animate(( scrollTop: $("#elementtoScrollToID").offset().top ), "slow"); )

    All body content is connected using #content div

    .... ....

    Assuming you have a button with a button id, try this example:

    $("#button").click(function() ( $().animate(( scrollTop: $("#elementtoScrollToID").offset().top ), 2000); ));

    I wrote this lightweight plugin to make page/element scrolling easier. It is flexible where you can pass in the target element or given value. Perhaps this could be part of jQuery's official release, what do you think?

    Examples of using:

    $("body").scrollTo("#target"); // Scroll screen to target element $("body").scrollTo(500); // Scroll screen 500 pixels down $("#scrollable").scrollTo(100); // Scroll individual element 100 pixels down

    Options:

    scrollTarget: An element, line, or number that indicates the desired scroll position.

    offsetTop: A number that specifies the extra space above the scroll.

    duration: A string or number that specifies how long the animation will take to run.

    easing: A string indicating which attenuation function to use for the transition.

    complete: A function to call after the animation has completed.

    To show the full element (if possible with the current window size):

    Var element = $("#some_element"); var elementHeight = element.height(); var windowHeight = $(window).height(); var offset = Math.min(elementHeight, windowHeight) + element.offset().top; $("html, body").animate(( scrollTop: offset ), 500);

    It has long since taken root among developers.
    So. With the help of the plugins presented in this collection, you can create a modern website with excellent dynamics. I think every person who is interested in website development has seen these plugins in action. When scrolling the page, blocks, various elements or text smoothly appear, move out, spin, etc. As practice shows, clients really like such fancy stuff.
    Implementing scrolling effects on a page is not as difficult as it might seem at first glance. All you need is a high-quality plugin and direct hands. Of course, a novice layout designer may experience difficulties, but if you sit for a while, understand the principles of operation, the task will seem very simple.
    Despite the fact that many people like animation on the site, you should not overdo it, otherwise you will end up with an overloaded, visually poorly perceived page in which all attention will be focused on all these “whistles”, and not on the information that needs to be conveyed to the visitor . In addition, the more scripts are connected, the slower the page works. In older browsers this whole thing may not work at all. Connect effects wisely. Often, a simple smooth, unobtrusive appearance of blocks is enough. This effect gives the page smoothness and dynamics, making the site alive. In my practice, I have seen a lot of sites with effects without a sense of proportion. This just makes me sick - the only feeling that arises. But, probably, the developers were hoping for a “Wow effect”. So. Use everything wisely and in moderation!
    All plugins are absolutely free, but I would recommend familiarizing yourself with the licenses, as in some cases you need to meet a number of conditions to use them for commercial purposes.

    WOW.jsA good plugin for implementing animation of elements when scrolling. It has a lot of animated block appearance options and is quite easy to customize. ScrollMagic Another popular plugin with which you can implement complex animations that will trigger when the mouse scrolls. In this case, the plugin allows you to create really complex motion effects, changing the background of the page and generally deforming shapes. ScrollMagic is often used on promotional sites that require a lot of animation.

    ScrollmeA simple and lightweight plugin with which you can implement spectacular animation when scrolling. You can scale, rotate, move, reduce or increase the transparency of any element.

    Superscrollorama Superscrollorama is a powerful but heavy plugin for creating scrolling animations. Its arsenal includes many different settings for animation of text, individual DIV elements, including effects.
    More detailed information can be found in the documentation for this jQuery plugin.

    onScreen is an excellent plugin that we often use in our projects. It allows you to easily and quickly create various effects for the appearance of elements when scrolling a page. The plugin is lightweight and does not load the page.

    OnePagejQuery OnePage plugin allows you to split a page into separate screens with a height of 100% and animate the transition across them. All it takes is a gentle nudge to start scrolling to the next screen. The same effect was used on the 5s promotional site.
    There are problems with, as with almost all similar plugins. If the text does not fit in height, it is simply cut off and the scroll bar does not appear.

    FSVS Very similar in functionality to the previous plugin. Allows you to make sliding scrolling across screens using css3. Has a similar problem when viewing on phones. Navigating through the screens in the form of separate slides is possible either using the mouse roller or by clicking on the dot side navigation.

    jInvertScrolljInvertScroll allows you to create cool horizontal parallax scrolling. While you roll the mouse roller down, all the elements on the page move horizontally, and at different speeds, which creates a parallax effect.

    WaypointsWaypoints is a jQuery plugin that allows you to show any element when the visitor is at a given point on the page. For example, when a visitor finishes reading an article on a website and approaches the end of the text, an information window pops up on the side of the page asking him to read the next article or a similar article.

    ScrollocueOriginal plugin for specific tasks. Allows you to move around the page by selecting blocks by simply right-clicking on the page. With each new click, the element below is highlighted, thereby scrolling the page a little. Scrolling with arrow keys on the keyboard is also supported.

    Scrolling Progress BarAn interesting solution with which you can show the progress of reading information on a page. It is also possible to divide the text into sections and all this will be visually displayed in any place convenient for you on the page.

    multiScroll.jsmultiScroll.js is a jQuery plugin similar to the two previous slip screen plugins, but has one significant difference. If in previous cases the screen was simply flipped, then this one is more like a modern image slider. The screen is divided into two equal parts and the left one scrolls up and the right one scrolls down. This way the content is practically torn apart.
    This plugin can be used, for example, to create a portfolio for a photographer or designer. I think visitors will appreciate your site.

    browserSwipe.jsAnother full-screen scrolling plugin, with the help of which you create an effective transition across screens. Available effects include sliding transition, full-screen rotation transition, scaling and horizontal scrolling across screens. You can combine all effects on one page.

    jQuery.panelSnap Fullscreen sliding scrolling plugin. At first glance, the plugin is no different from the previous ones, but it has an internal scrolling area. If we scroll to the end of the internal content, then the transition to the next screen automatically occurs. Theoretically, this is a solution to the problem for responsive websites. If the inner window is made full size, on small screens content that does not fit in height will not be lost.

    Hello friends. In this article, we will look at the jQuery event when the page scrolls to a specific element. In other words, then... In this example, we will fire an event when the page is scrolled to the footer. Then we will display a small pop-up window with a smooth appearance. And we will also close it by clicking. Decide for yourself what to put in it, there are plenty of options. This is what it looks like:

    Let's start with the HTML markup and there is nothing unusual here. Everything is quite simple and clear. A large canvas of text, a footer at the bottom and a block with a button that will appear. Here is the block code:

    1 2 3 4 5 6 7 8 9 10 There's a lot of content here... Some text. Footer

    There's a lot of content here... Some text. Footer

    Now let's start designing our hidden block and its button:

    1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 #block ( display : none ; position : fixed ; top : 15px ; right : 15px ; color : #fff ; background : #4CAF50 ; padding : 10px ; border-radius : 5px ; width : 200px ; box-shadow : 0 13px 20px -5px #3a3a3a ; font-family : Arial ; text-align : center ; .btn( background : #FF9800 ; border : 2px solid #795548 ; color : #fff ; border-radius : 5px ; cursor : pointer ; padding : 5px 10px ; margin-top : 10px ; font-weight : bold ;

    #block( display: none; position: fixed; top: 15px; right: 15px; color: #fff; background: #4CAF50; padding: 10px; border-radius: 5px; width: 200px; box-shadow: 0 13px 20px -5px #3a3a3a; font-family: Arial; text-align: center; .btn( background: #FF9800; border: 2px solid #795548; color: #fff; border-radius: 5px; cursor: pointer; padding: 5px 10px; margin-top: 10px; font-weight: bold)

    Now let's deal directly with what is called scroll to element. Still, English is necessary for a developer. We connect jQuery as standard. I'll do this via CDN as it will be the most up to date version.

    And then the script code itself, which will create magic on the page:

    1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 $(document).ready (function () ( var $element = $(".footer" ) ; let counter = 0 ; $(window).scroll (function () ( var scroll = $(window).scrollTop () + $(window).height () ; //If scroll to the end of the element //var offset = $element.offset().top + $element.height(); //If scroll to the beginning of the element var offset = $element .offset () .top if (scroll > offset && counter == 0 ) ( $("#block" ) .fadeIn (500 ) ; counter = 1 ; ) ) ; $(".btn" ) .click (function () ( $("#block" ) .slideUp () ; ) ) ;

    $(document).ready(function())( var $element = $(".footer"); let counter = 0; $(window).scroll(function() ( var scroll = $(window).scrollTop() + $(window).height(); //If scroll to the end of the element //var offset = $element.offset().top + $element.height(); //If scroll to the beginning of the element var offset = $element .offset().top if (scroll > offset && counter == 0) ( $("#block").fadeIn(500); counter = 1; ) )); $(".btn").click(function ()( $("#block").slideUp(); ));

    By default, the event is triggered as soon as the beginning of the element, in this case the footer, appears in the visibility area, but you can change the value by uncommenting line 7 and then the function will fire when the scroll reaches the end of the element.

    This is a clever way to show site visitors your unique offer and by adding goals to the metric, track its conversion.
