Answer 1

1. Download the map file and the uncompressed version of jQuery.
   Put them with the minified version:

   

2. Include minified version into your HTML:

   

3. Check in Google Chrome:

   

4. Read Introduction to JavaScript Source Maps

5. Get familiar with Debugging JavaScript

Answer 2

As I understand the browser, Chrome at least, it doesn't disable the source mapping by default. That means your application's users will trigger this source-mapping request by default.

You can remove the source mapping by deleting the //@ sourceMappingURL=jquery.min.map from your JavaScript file.

Answer 3

jQuery 1.11.0/2.1.0 the // sourceMappingURL comment is not included in the compressed file.

Answer 4

Assuming you've checked the file is actually present on the server, this could also be caused by your web server restricting which file types are served:

• In Apache this could be done with with the <FilesMatch> directive or a RewriteRule if you're using mod_rewrite.
• In IIS you'd need to look to the Web.config file.

Answer 5

If you want to get source map file different version, you can use this link http://code.jquery.com/jquery-x.xx.x.min.map

Instead x.xx.x put your version number.

Note: Some links, which you get on this method, may be broken :)

Answer 6

After following the instructions in the other answers, I needed to strip the version from the map file for this to work for me.

Example: Rename

jquery-1.9.1.min.map

to

jquery.min.map
