Script src Property

❮ Script Object

Example

Get the URL of an external script file:

var x = document.getElementById("myScript").src
Try it Yourself »

Description

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.
