What is HTML <script> src Attribute

The <script> HTML element is used to embed executable code or data; this is typically used to embed or refer to JavaScript code. The <script> element can also be used with other languages, such as WebGL's GLSL shader programming language and JSON.

Definition and Usage

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.
