The main way to insert JavaScript into an HTML page is to use the 3f1c4e4b6b16bbbd69b2ee476dc4f83a element. The

3f1c4e4b6b16bbbd69b2ee476dc4f83a element has two commonly used attributes:

● src: Indicates the external file containing the code to be executed. The src attribute is required if you want to include external JavaScript files through the 3f1c4e4b6b16bbbd69b2ee476dc4f83a element. The value of this attribute is a link to an external JavaScript file.

Note: The 3f1c4e4b6b16bbbd69b2ee476dc4f83a element with the src attribute should not contain additional JavaScript code between its 3f1c4e4b6b16bbbd69b2ee476dc4f83a and 3f1c4e4b6b16bbbd69b2ee476dc4f83a tags. If embedded code is included, only the external script file will be downloaded and executed, and the embedded code will be ignored. JavaScript files from external domains can also be included via the src attribute of the 3f1c4e4b6b16bbbd69b2ee476dc4f83a element.

Example:

<script src="example.js"></script>
<script src="//m.sbmmt.com/js/example.js"></script>

● Type: Specifies the MIME type of the script. The type attribute indicates the content between the 3f1c4e4b6b16bbbd69b2ee476dc4f83a and 2cacc6d41bbb37262a98f745aa00fbf0 tags.

Description: MIME type includes two parts: media type and subtype. For JavaScript, the MIME type is "text/javascript".

Note: In HTML5, the type attribute is no longer required. The default value is "text/javascript". JavaScript is the default scripting language in HTML5 and all modern browsers.
