How to enable javascript execution in the browser. How to enable javascript in Yandex

Beginners 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, except battery life. This technology is aimed at working only with browsers. The script is initially placed in HTML files where it provides stable work and the 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 carrying out additional compilation.
• The reliable operation of each technology lies in connecting different modules.
• The operating 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

• 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 scripts” appears in front of you Java applications».
• 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 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.

• Scroll down the window and open "Advanced Settings".

• 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.

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 ensured special programs and modules written in the language Java programming. And, although they usually launch automatically, due to the Yandex built into the browser Java technologies script, sometimes you need to enable it manually.

What is JavaScript?

Home Javascript task is the execution of 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.

Default work Java scripts activated 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 return the capabilities of the site and correct display pages should make support for Java scripts available again for Yandex.

Stages of inclusion

To enable Javascript, do the following:

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

• 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 Manage Extensions menu, you can only allow Java to be used on certain sites by enabling them in the " White list" 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.

Brief information about using JavaScript in different versions of web browsers.

JavaScript is not supported by: text browsers like Lynx, w3m, Links, old versions of desktop browsers Netscape Navigator, Internet Explorer; browsers in most models mobile phones: Opera Mini, NetFront, Bold, Minimo, Doris, as well as some graphical browsers: Amaya, DittoB. Partially JavaScript supported text browser eLinks(at the level simple scripts). In some browsers, on the contrary, it is possible to disable JavaScript execution via user interface, missing for example in Google Chrome up to version 10.
The JavaScript option is enabled in all modern web browsers: Internet Explorer, Opera, FireFox, Safari, Chrome, by default, i.e. when installing the browser into the operating system. JavaScript is disabled by the following reasons: when the browser is used by several users with different views on web surfing, during updates software, when blocking protective programs: antiviruses, anti-Trojans, anti-advertising.
Please note that blocking Java Script may be caused by the use of firewalls (firewalls, firewalls), proxy servers, anonymizers. In these cases, changing the JavaScript option policy must be performed not in the browser, but in these programs. Often a message about disabling JavaScript arise due to incorrect web server settings or the use of rare JavaScript versions and frameworks on the pages, this should be reported to the administrator of a site like this. It is extremely rare that script execution fails when the program code JavaScript interpreter in the operating system, solution similar problem perhaps only by involving a highly qualified specialist.
Note that some users intentionally disable Java and JavaScript in their browsers. This is due to the fact that, firstly: the execution of scripts and applets written in these languages ​​slows down the loading of web pages, and secondly, scripts and applets can be used by attackers to infiltrate malicious code viruses, Trojans, worms into the operating system. Disabling JavaScript for such users also speeds up the browser and protects against hacker attacks.
Note: Java and JavaScript, those are two different languages programming, permission to use them are separated in the settings of web browsers. Software interpreter JavaScript code, installed on all modern operating systems. But the Java platform, for some operating systems, if you need to run programs in Java, you will have to download from the official website and install it.
