IIS Change JavaScript Version

In web development, JavaScript is a very important programming language used to enhance the interactivity and functionality of dynamic web pages. However, different issues may arise when running JavaScript on different web servers. If you use Microsoft's Internet Information Services (IIS) as your web server, you may encounter compatibility issues with some JavaScript versions. To do this, you need to change the JavaScript version on IIS to ensure JavaScript runs properly on different browsers.

This article will provide detailed steps on how to change JavaScript version on IIS.

Step 1: Open Internet Information Services

First, click the Windows key R, type inetmgr, and press the "Enter" key. At this point, Internet Information Services (IIS) Manager will open.

Step 2: Select Application Pool

In IIS Manager, you will see the "Application Pool" option in the left menu. Clicking this option will display all available application pools.

Step 3: Select your web application pool

In the application pool list, you can see all the web application pools that have been installed on the server. Select the web application pool for which you want to change the JavaScript version and click on it.

Step 4: Change the .Net CLR version of the application pool

Right-click on the web application pool of your choice and select "Advanced Settings". In Advanced Settings, find the ".NET CLR Version" option and change it to the desired version. Select the JavaScript version to use.

IIS 7 and later supports multiple choices of JavaScript versions. These versions include:

· Default: This option will use the latest version of JavaScript installed on the web server.

·ECMAScript version: This is the basis of the current JavaScript version and includes some of the most basic JavaScript syntax.

·JavaScript version 1.1: This is one of the earliest versions of JavaScript and is obsolete.

·JavaScript version 1.2: This version includes various new features, such as the JavaScript object model and new element types.

·JavaScript version 1.3: This version includes the same features as JavaScript 1.2, as well as new array and string methods.

·JavaScript version 1.4: This version includes new string and number methods.

·JavaScript version 1.5: This version includes new features like JSON, and better exception handling.

·JavaScript version 1.6: This version includes new reduce and generator functions, as well as better exception handling.

·JavaScript version 1.7: This version includes new function declaration syntax, iterators and generator functions.

·JavaScript version 1.8: This version includes new features such as lambda expressions.

After selecting the desired JavaScript version, click OK to close the Advanced Settings window.

Step 5: Restart the Web Application Pool

After changing the JavaScript version, you need to restart the Web Application Pool. In IIS Manager, find the application pool you just selected, right-click and select "Advanced Management" and "Stop", then right-click again and select "Start".

Now you have successfully changed the JavaScript version on IIS. Different browsers will use different JavaScript versions to render your web application. Therefore, before publishing your web application, make sure to change the required JavaScript version to work well in various browsers.
