Please note that the export_add_js() function is not a part of WordPress core. It may have been added by a specific theme or plugin. Always check the source code of your specific installation to determine the exact behavior of this function.
Examples
Adding a JavaScript File
// This will display the 'main.js' JavaScript file on the page
export_add_js("main.js");
Loading a Script from a Subdirectory
// This will display the 'subfolder/script.js' JavaScript file on the page
export_add_js("subfolder/script.js");
Loading a Script from a Different Domain
// This will display the 'http://example.com/myScript.js' JavaScript file on the page
export_add_js("http://example.com/myScript.js");
Loading Multiple Scripts
// This will display the 'main.js' and 'extra.js' JavaScript files on the page
export_add_js("main.js");
export_add_js("extra.js");
Loading a Script Based on a Condition
// This will display the 'mobile.js' JavaScript file on the page only if the $isMobile variable is true
if($isMobile) {
export_add_js("mobile.js");
}
In the last example, we use a conditional statement to load a JavaScript file only when a certain condition is met. In this case, the ‘mobile.js’ script is loaded only if the $isMobile variable is true.
