How to Properly Use WP Enqeue Script

Snippets by IsItWP

Do you want to properly use the WP Enqeue script in WordPress? While there’s probably a plugin for this, we have created a quick code snippet that allows you properly use WP Enqeue script in WordPress.

Instructions:

All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:


function your_init_yourscript() {
    wp_deregister_script( 'jquery' );
    wp_register_script( 'jquery', 'https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js');
}
add_action('init', 'your_init_yourscript');

In your header file call the wp_enqueue_script before wp_head, like this:


<?php wp_enqueue_script( 'jquery' ); ?>

<?php wp_head(); ?>

And then put all your JavaScript code after wp_head.

You can give this function another name but don’t use my_init_method, because this will conflict with other WordPress functions.

After that you have to call your JavaScript using the no-conflict mode. This means that you can’t call the script using the $ shortcode but like this:


jQuery(document).ready(function({
// stuff
});

Note: If this is your first time adding code snippets in WordPress, then please refer to our guide on how to properly add code snippets in WordPress, so you don’t accidentally break your site.
