I am testing jQuery in my wordpress plugin. Two files 1. main_plugin.php 2. js_plugin.js (Both in the same directory HelloWorld).

Plugin Name: jQuery Test Plugin
Plugin URI: http://www.rabwahnetwork.net
Description: This plugin is a test
Author: Rana Faiz Ahmed
Author URI: http://www.rabwahnetwork.net

function load_my_script()
    wp_enqueue_script( 'script-name', WP_PLUGIN_URL . 'HelloWorld/js_plugin.js', array("jquery"), false, true );

add_action( 'wp_enqueue_scripts', 'load_my_script' );

JS file:

jQuery('.entry-header').click(function(e) {

WP_PLUGIN_URL doesn't have a trailing slash, so your script tag is likely trying to load a file from the wrong location.

That said, don't use WP_PLUGIN_URL, use plugins_url() instead.

plugins_url( '/HelloWorld/js_plugin.js' )
  • Nope, no effect!

  • Yeah I'm editing it from the wordpress backend. Absolutely it is being loading else I wouldn't be editing it.

  • whether or not you can edit a file on the back end has nothing to do with whether or not it's successfully loading on the front end, your assumption is incorrect.
