JavaScript is a programming language that can add various interactivity, dynamics and multimedia effects to websites. However, sometimes you open a web page and find that JavaScript is not working properly. This may be because JavaScript is not enabled in the browser. This article explains how to set up and enable JavaScript.
Step one: Open browser settings
Different browsers have different ways to open it. In most browsers, you can find JavaScript-related options by going to Settings or Options in the menu, then Content Settings or Privacy Settings.
In Chrome, you can find "Settings" in the three dots in the upper right corner of the browser, then select "Privacy & Security," then find "Site Settings" and select the "JavaScript" option.
In Firefox browser, you can find "Options" in the three horizontal lines in the upper right corner of the browser, click "Privacy and Security", and then find "Site Configuration" in the "Security" section, Click the "Custom Level" button and find the JavaScript option.
Step 2: Turn on JavaScript
After opening the corresponding settings interface, you should be able to find the "JavaScript" option. In most browsers, JavaScript is enabled by default. But if it is not enabled, you can easily find the "Enable" or "Enable JavaScript" option.
In the Chrome browser, find the "JavaScript" option and select "Allow all sites to run JavaScript (recommended)" or "Only the following sites" and then select the sites you want to allow JavaScript to run. Add to list.
In the Firefox browser, find the "JavaScript" option and select "Enable JavaScript". You can also choose to "Allow all sites to run JavaScript" or "Only run JavaScript when I ask you to", as well as "Prevent sites with older or insecure versions of JavaScript from running."
In Safari browser, in the "JavaScript" option, select "Enable JavaScript".
In IE browser, in "Internet Options", select the "Security" tab and select "Custom Level", then select "Enable" under the "Scripting" option.
