Definition and Usage

The src property 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 a web 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 then refer to it using the src attribute in the <script> tag.

Note: The external script file cannot contain the <script> tag.

Note: Point to the external script file exactly where you would have written the script.

Browser Support

Internet Explorer Firefox Opera Google Chrome Safari

The src property is supported in all major browsers.

Syntax

Return the src property:

scriptObject.src

Set the src property:

scriptObject.src=URL
