I am trying to make a mobile navigation for my site. However the jquery code won't work. You can see what I am trying to do here: jsfiddle.
I have the html in my header.php after body tag, css in my style.css
For javascript I enqueued it in my functions php:

wp_enqueue_script( 'test', get_template_directory_uri() . '/js/testJS.js', array('jquery'), true );

In my testJS.js I have this code:

( function( $ ) {
} )( jQuery );

But when I click on the button nothing happens unlike my jsfiddle. Can someone tell me what I did wrong? Thanks in advance!

  • Is your enqueued JS file appearing in the source code for your website?

  • Yes it is but after I just checked, it seems to be on the top in the head tag for some reason. I think this might be the problem. Commented Aug 22, 2016 at 22:19
  • Shouldn't matter too much - as long as it's included after the jquery script is - are there any errors in your browser's console?

  • No there are no errors.. Commented Aug 22, 2016 at 22:26
  • Are there any console errors after you have clicked on your navigation icon?

Try loading your script in the footer:

wp_enqueue_script( 'test', get_template_directory_uri() . '/js/testJS.js', array('jquery'), false, true );`

The true parameter on the end tells WordPress to load this script in the footer instead of the header.
