Asp net mvc4 change jquery version

Introduction

ASP.NET is a popular programming language used for building web applications. One common requirement in web development is the need to change the version of jQuery used in an ASP.NET MVC4 . In this article, we will explore how to accomplish this task with examples.

Step 1: Locate the jQuery file

The first step is to locate the jQuery file that is currently being used in the ASP.NET MVC4 project. This file is typically located in the “Scripts” of the project. Open the project in Visual Studio and navigate to the “Scripts” folder to find the jQuery file.

Step 2: Download the desired jQuery version

Next, you need to download the desired version of jQuery that you want to use in your ASP.NET MVC4 project. Visit the official jQuery website (https://jquery.com/) and download the version you prefer. Save the downloaded file in a location that is easily accessible.

Step 3: Replace the jQuery file

Now, it's time to replace the existing jQuery file with the downloaded version. Copy the downloaded jQuery file and paste it into the “Scripts” folder of your ASP.NET MVC4 project, replacing the existing file. Make sure to give the new file the same name as the old one.

Step 4: Update the BundleConfig.cs file

The next step is to update the BundleConfig.cs file in your ASP.NET MVC4 project. This file is responsible for the bundling and minification of JavaScript and CSS files. Open the BundleConfig.cs file and locate the code that registers the jQuery file. Update the file path to point to the new jQuery file that you just replaced.


bundles.Add(new ScriptBundle("~/bundles/jquery").(
    "~/Scripts/jquery-{version}.js"));

In the above code snippet, replace “~/Scripts/jquery-{version}.js” with the path to your new jQuery file. For example, if your new jQuery file is named “jquery-3.6.0.js” and located in the “Scripts” folder, the updated code should look like this:


bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
    "~/Scripts/jquery-3.6.0.js"));

Step 5: Update the file

The step is to update the layout file of your ASP.NET MVC4 project. The layout file is typically named “_Layout.cshtml” and is located in the “Views/” folder. Open the layout file and locate the code that references the jQuery file. Update the file path to point to the new jQuery file that you just replaced.



In the above code snippet, replace “~/bundles/jquery” with the path to your new jQuery file. For example, if your new jQuery file is named “jquery-3.6.0.js” and located in the “Scripts” folder, the updated code should look like this:



Conclusion

By the steps outlined in this article, you can easily change the version of jQuery used in your ASP.NET MVC4 project. Remember to locate the existing jQuery file, download the desired version, replace the existing file, update the BundleConfig.cs file, and update the layout file. With these changes, your ASP.NET MVC4 project will be the new version of jQuery.
