Definition and Usage

The src attribute sets or returns the value of the src attribute of a script.

The src attribute specifies the URL of an external script file.

If you want to run the same JavaScript on several pages in your site, you should create an external JavaScript file, instead of writing the same script over and over again. Save the script file with a .js extension, and refer to it using the src attribute in the <script> tag.

Note: The external script file cannot contain script tags.

Note: Reference the external script file correctly that you write into the script.
