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
The src property is supported in all major browsers.
Syntax
Return the src property:
scriptObject.src
Set the src property:
scriptObject.src=URL
