How to enable javascript in Yandex. How to enable javascript in the browser - instructions for all versions Enabling javascript support

Nowadays, almost all web pages use JavaScript, a scripting programming language that runs on the visitor's web browser.

JavaScript is a scripting language that can be used to embed small programs into an HTML document (website page) that make it easier to work with an HTML page and make it more beautiful.

Therefore, in order to see the pages of sites colorful, with the full range of functionality, you must enable JavaScript in your browser.

Accordingly, if avaScript is disabled for some reason, the content or functionality of the web page may be limited or not possible at all.

Some sites ask you to enable JavaScript when loading, because without it the page will not load completely, if at all.

Here you can find instructions on how to enable (activate) JavaScript in the five most common web browsers.

I hope that the information is useful: o).

Accordingly, most of the time you have to work with the browser. To make the work in the program wider, and all the viewed content looks better, the developers are introducing some additional elements. In this article, we will take a detailed look at how to turn JavaScript on or off in your browser, as well as what it is and how it can affect your browsing experience. Let's figure it out. Go!

JavaScript is a programming language that runs in the browser that makes websites look better and be more functional. How to activate it in a specific browser, later in the article.

Starting Chrome, click on the icon in the upper right in the form of three horizontal stripes to open the menu. Then select "Settings". In the window that appears, click on the "Show advanced settings" button. Next, in the section with personal data, go to the content settings. Then enable JavaScript on all sites.

While in the program, go to the tool window. In the list that opens, click on "Settings". On the "Content" tab, check the box next to "Use JavaScript". Note that newer versions of Mozilla do not need to enable this feature, as it is enabled by default. To disable, write in the address bar (without quotes) "about: config". In the search field, write "javascript.enabled". Having marked the lines with the “default” state, click on the “Toggle” button.

This will allow you to customize the look of the pages, making them more functional or more secure, depending on your preferences. Write in the comments if the article was useful to you and ask if you have any questions on the topic.

JavaScript(Java script) is a programming language widely used to create websites. If JavaScript support is disabled in the web browser options, then some services on websites become unavailable. For example: ordering, paying for goods in online stores, pharmacies, bidding at auctions, posting information on bulletin boards, exchanging and converting web currencies, communicating in social networks: Odnoklassniki, VKontakte, MoiMir, FaceBook, etc. etc..
Quite often, a special warning is set on the pages of sites, which is displayed on the pages of sites, if they are viewed with the JavaScript function disabled in the browser. For example:
Your browser does not support JavaScript
Please enable JavaScript to view this page
JavaScript may be disabled in your browser settings
Unfortunately, your browser's JavaScript is disabled. Please enable it

Brief information about the use of JavaScript, in various versions of web browsers.

JavaScript is not supported by: text-based browsers like Lynx, w3m, Links, old versions of desktop browsers Netscape Navigator, Internet Explorer; browsers in most mobile phone models: Opera Mini, NetFront, Bold, Minimo, Doris, as well as some graphical browsers: Amaya, DittoB. JavaScript is partially supported by the text browser eLinks(at the level of simple scripts). In some browsers, on the contrary, the ability to disable JavaScript execution through the user interface is 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 in the operating system. JavaScript is disabled for the following reasons: when the browser is used by several users with different views on web surfing, during software updates, when blocked by security programs: antiviruses, antitrojans, anti-advertising.
It should be noted that Java Script blocking can be caused by the use of firewalls (firewalls, firewalls), proxy servers, anonymizers. In these cases, changing the JavaScript option policy needs to be done, not in the browser, but in those programs. Often, messages about disabling JavaScript arise due to incorrect settings of web servers or the use of rare versions of JavaScript and frameworks on pages, this should be reported to the administrator of a site like this. It is extremely rare that a script execution failure occurs when the JavaScript interpreter program code in the operating system is damaged; a solution to such a problem is possible only by attracting a highly qualified specialist.
Note that some users disable Java and JavaScript in their browsers on purpose. This is due to the fact that, firstly, the execution of scripts and applets written in these languages ​​slows down the unloading of web pages, and secondly, scripts and applets can be used by attackers to inject malicious code of viruses, trojans, worms into the operating system. system. Disabling JavaScript "s, for such users, is the acceleration of the browser, protection from hacker hacking.
Note A: Java and JavaScript are two different programming languages, the permission to use them is separated in the settings of web browsers. The JavaScript code interpreter is installed on all modern operating systems. But the Java platform, for some operating systems, if Java programs are required, you will have to download and install from the official site.

JavaScript is one of the programming languages ​​that is commonly used to programmatically access application objects. Often it is built into the browser and is necessary in order to make web pages more functional. Accordingly, if JavaScript is disabled for one reason or another, then the page may not open at all or it will open, but with significant limitations or errors. For example, certain text may not be displayed. Therefore, if you do not know how to activate this language in your Internet browser, then you have come to the right place.

By default, on almost all Internet browsers, JavaScript is used by default, and it is usually disabled by the user himself.

As for the use of the language, it is necessary, for example, in some web applications, scripts in browsers (we are talking about special programs that allow you to format pages, automatically fill out forms, hide some content, and so on), as well as in AJAX ( an approach to building application interfaces in which data is exchanged with the server in the background, due to which the page is not completely reloaded, and the application itself only speeds up).

How to enable javascript in the browser - instructions for all versions

For the full and optimal operation of web pages in a browser, it is necessary that javascript be activated in it.

What it is and how to enable it, we will explain in this article.

What is javascript?

JavaScript can be called a multi-paradigm language. It has support for many ways of programming. For example, object-oriented, functional and imperative.

This type of programming is not directly related to java in any way. The main syntax of this programming language is the C language, as well as C++.

The basis of browser web pages is HTML code, with the help of which programmers add various interactive elements to pages.

If javascript is disabled in the browser, interactive elements will not work.

This type of programming language appeared thanks to the joint work of Sun Microsystems and Netscape.

Initially, JavaScript was called LiveScript, but after the Java language became popular among programmers, the development companies decided to rename it.

Netscape's marketing department thought that such a name would increase the popularity of the new programming language, which, in fact, happened.

Recall that JavaScript is not directly related to Java. They are completely different languages.

JavaScript Features

This programming language has an unlimited number of possibilities due to its versatility.

The main aspects of the application are mobile applications for smartphones, interactive web pages of sites and services.

Most of the innovation came from joining the project with AJAX, which provided the features used in the language today.

To save traffic and increase ease of use, JavaScript provides the ability to change the pages of sites and services in small parts without the user noticing online.

This does not require the site to be offline while editing or adding new information.

Changes happen immediately without requiring a refresh or page reload.

The JavaScript feature can be disabled for various reasons.

It is possible that the previous user may have intentionally disabled it, as it was not required for web browsing. Also, the shutdown could happen on its own.

Disabling javascript may cause some links to fail. Below we will look at ways to enable this feature in popular browsers.

In the "Javascript" section, check the box "Allow Javascript on all sites" and save the changes by clicking the "Finish" button.

After that, JavaScript is immediately activated and will allow you to view previously inaccessible web pages and perform manipulations on interactive services.

After activating the function, the browser itself does not need to be restarted, you only need to refresh the page by pressing the F5 key or the corresponding icon on the left of the address bar.

In the latest version of the browser, JavaScript activation is installed automatically, so there is no option to enable the function in the settings.

Conclusion

Today, almost all developers use javascript when creating websites.

Therefore, for the correct operation of sites, it is often recommended to enable this function in your browser.

Javascript is a universal programming language.

With it, almost all modern websites and services are able to provide GIF animation, as well as clickable links and attachments.

JavaScript also allows you to correctly use flash-games and applications, for example, VKontakte games.

But having an activated function is not enough for this.

The latest version of Adobe Flash Player must be installed on the computer system.

In other cases (for example, browser games), the presence of a flash player may be optional.
