Which is embedded in the html code of pages to give them greater functionality.

Thanks to the scripting language, the page becomes interactive or dynamic, which improves the contact with the user. The language is not used to write individual applications and only works inside the program, in the browser. Scripts do things on web pages that are not available. Scripts are executed if the user takes any action: moves the cursor, clicks, etc. Using JavaScript, a creeping line effect is created, pictures change after hovering the cursor, and questionnaires or registration forms are filled out.

If you disable JavaScript in your browser, you may not be able to view some websites or the pages will become static and therefore inanimate. How to enable JavaScript support?

Beginner users often confuse or mismatch programming languages ​​such as Java and JavaScript. This is due to their similar name, which evokes corresponding analogies. The only thing in which they are similar is the goal of making familiar web resources more convenient to use.

In this article, we will look at the differences between these programming languages ​​and figure out how to activate Java in browsers if a plugin or script was accidentally disabled.

What is the difference

Let's start with a simple explanation of the difference between the two technologies given above. Java is a technology created to develop applications that can run offline or through browsers.

Regarding JavaScript, everything is similar, with the exception of offline operation. This technology is designed to work only with browsers. The script is initially placed in HTML files, where it ensures stable operation and exchange of data between web pages and the browser.

To supplement the information received, we will give an example of the main differences between these languages.

  • Unlike Java, JavaScript comes in text format, which is much easier than additional compilation.
  • The reliable operation of each technology lies in connecting different modules.
  • The algorithms of the languages ​​are completely different and have practically nothing in common.

Working with the Java Plugin

Before you start working with the plugin, you will need to download it from the official source located at https://java.com/ru/download/. As a precaution, disable your antivirus's firewall, otherwise there is a chance of your download being blocked.

  • As soon as you follow the link provided, a window will open where there will be a red button with the inscription “Download Java for free”.
  • Click on it and wait for the download to finish.
  • Run the source file.
  • A small launcher window will appear, where you need to click “Install”.

After a short installation, the plugin will be available for use on your computer.

How to enable Java in the browser

Installing Java only solves the main problem in gaining access to the plugin. Now you need to check its functionality through the browser.

Internet Explorer

  • In the upper right corner there is a gear that you need to click on.
  • A small menu will appear, select Internet Options.
  • Here you need to find the “Security” section and click on the “Other” item.
  • Rotate the window that appears until the talking block “Run Java application scripts” appears in front of you.
  • You can enable it using the checkbox on the left.
  • The “OK” key will allow you to save the new settings and exit.

Google Chrome

The project developers limited access to working with plugins after the release of version 42 of the browser in 2015. In simple words, it will not be possible to launch Java using available tools.

Firefox

This web browser left users the opportunity to independently adjust many aspects of the program.

  • First of all, go to your browser settings.
  • Select "Tools" and then go to the "Plugins" block.
  • Here is the self-explanatory name “Java”. You need to click on it.
  • Pay attention to the set value. For the extension to work, the “Always Activate” or “Request Activation” option must be set. It changes depending on the user's wishes.

How to enable JavaScript

Many sites resort to using Javascript in order to provide more features to their users. Let's find out how to enable this feature in popular browsers.

Google Chrome

  • Go to “Settings” using the context menu in the form of three dots located in the upper right corner.
  • Scroll down the window and open "Advanced Settings".
  • In the “Privacy and Security” block that appears, select “Content Settings”.
  • Pay attention to the “JavaScript” item and open it.
  • There should be an active toggle switch opposite the inscription “Allowed”.

When making changes, be sure to restart your browser.

Internet Explorer

  • Go to the system settings using the gear icon.
  • Go to the "Internet Settings" section.
  • From here, navigate to the "Security" block by clicking "Advanced" here.
  • What is important to us here is the block with the self-explanatory name “Scripts”. It contains the “Activate Scripts” section, which should be in the “Enabled” state.
  • An activation window will follow, where you just have to click “Yes”.

As in the previous case, you must restart your browser for the changes to take effect.

Mozilla Firefox

In this case, everything is much simpler compared to the options above.

  • Open the Tool menu and select Settings.
  • We need the “Content” block, it is third on the list.
  • Visit it, check the box next to “Use JavaScript”.
  • Confirm the action using the “OK” button.

Yandex browser

The domestic project requires spending a little more time navigating to the control menu.

  • Visit the “More” submenu, shown as three lines.
  • Rotate the window that opens to the very bottom until you come across “Show advanced settings”.
  • Get to "Personal Information". Select Content Settings.
  • There is a section dedicated to Javascript; in it you need to check the box next to “Allow JavaScript on all sites”.
  • All you have to do is click “Finish”.

If necessary, the script can be configured for individual Internet resources; all you need to do is devote a little time to the “Exception Management” settings.

Opera

Everything is as simple as possible here:

  • Visit the Settings section.
  • Immediately go to the “Advanced” tab and switch to the “Contents” item. Next to “Enable JavaScript”, check the box.

Conclusion

It is quite simple to enable any of the Java languages; it is only important to understand the settings of web browsers.

Most web pages are not just formatted text with images inserted into it. Many resources are equipped with animated pictures, buttons and video players.

The operation of these elements is provided by special programs and modules written in the Java programming language. And, although they usually run automatically due to the Javascript technology built into the Yandex browser, sometimes it needs to be enabled manually.

What is JavaScript?

The main task of Javascript is to execute certain scripts in the user's browser. In this case, the modules used, written using this language, are called scripts. Built into the page code, they are responsible for certain actions - for example, pressing buttons. When scripts are disabled, a significant portion of sites lose functionality and become inoperable.

By default, Java scripts are enabled in any browser, including Yandex. However, due to viruses, malicious codes and other failures, it may be turned off. Sometimes scripts are accidentally disabled by users. And in order to restore the capabilities of the site and the correct display of the page, support for Java scripts should be made available again to Yandex.

Stages of inclusion

To enable Javascript you should do the following:

  • Launch the Yandex browser;
  • Open the control panel (if it was closed) by clicking on the button with three horizontal stripes located to the left or below the standard window control buttons;

  • In the menu that appears, select “Settings”;
  • Scroll the list of settings to the end and select “Show additional settings”, after which several more items will open;

  • Find the “Personal Data” group and open the content settings item located at the top of it;

  • Select the JavaScript category and check the box that allows the use of the technology on all sites;

  • After clicking the “Finish” button, you should close the browser and launch it again.

Using the extension management menu, you can allow Java to be used only on certain sites, which will require you to whitelist them. Or, conversely, block it on resources that seem suspicious to you by adding them to the exclusion list.

In the field for entering information, you should copy the addresses of all sites, the permissions for which will differ from the settings for all other web pages. And then choose the appropriate action - permission or prohibition. This way, for example, you can protect yourself from pop-ups.

Java connection

If problems with displaying sites in the browser still remain, it is possible that problems exist not in the operation of JavaScript, but in the entire Java technology. In order to enable it you need:

  • launch browser;
  • copy or enter browser://plugins/ into the address bar and select Enter;
  • press Enter;
  • Find Java in the list that appears on the screen and select “Enable”;
  • If there is no corresponding item, install the plugin by going to the page https://www.java.com/ru/download/, click on the “Download for free” button and follow the Install Wizard instructions.

Instructions

In Mozilla Firefox, go to the Tools menu and find Settings. Select “Use JavaScript” in the “Content” tab of the window that opens. Check the box next to it. To fine-tune the scenarios, click on the “Advanced” button in this line.

In Windows Internet Explorer, show the menu bar if it is not visible by right-clicking the top margin. From the Tools menu, go to Internet Options. Activate the “Security” tab window, find the “Other...” button and click on it. In the Security Settings window that opens, scroll down the list until you reach the Scripts section. Place a dot next to “Enable” in the “Active Scripts” subsection.

To enable JavaScript in the K-Meleon Internet browser, on the “Tools” tab, find the “Privacy” item. Enable script support with the “Block JavScript” switch, that is, uncheck the box next to it.

In the Konqueror web browser, go to the Tools menu, click HTML Options, and check the javaScript box.

Connection scripts in the Opera browser, do it through the “Tools” menu. In the Settings window, go to the Advanced tab. Find the Content section and check Enable JavaScript. For optional settings, there is a “Configure JavaScript” button. Click it and set the desired script parameters.

In the Apple Safari Internet browser, go to the “Security” tab located in the “Settings” menu. Click in the box next to “Enable JavaScript”.

The Google Chrome browser supports JavaScript by default. In the event that the scripts still do not work on the pages you open, right-click on the browser shortcut, select “Properties” and check if there is a disable-javascript option in the “Object” field, which is set on the command line.

Everyone wants to make their website more interesting for the user. Most often used for this scripts, they provide great opportunities for the development of Internet projects.
