Wordpress: jQuery inside a Wordpress Plugin?

PHP
1

Yeah, i’m not that familiar with JavaScript at all, but I have a need to add some nice functionality to a plugin i’m trying to create and jQuery (for me) would be the logical choice. I can’t seem to get jQuery to work though even though I have read multiple blog posts on the topic. Something is clearly wrong with my code. If you don’t mind taking a peek, I’ve shown the pertinent information of the plugin and the javascript file. Any help would be greatly appreciated!

The Goal: Simply use jQuery to toggle the <div> with the id “level2details” from visible/non-visible and vice-versa with each click on <div> with the id “toggle”.

Plugin Code (some parts removed for clarity)

<?php
function start_jquery() {
    wp_enqueue_script('jquery');            
}    
 
add_action('init', 'start_jquery');

function pluginname_page() {

  if (!current_user_can('manage_options'))  {
    wp_die( __('You do not have sufficient permissions to access this page.') );
  }

  echo '<div class="wrap">';
  ?>
<script type="text/javascript" src="/js/pluginname.js"></script>
  <div>
  	<div id="level1"><a href="#">General Fund</a></div>
    	<div id="toggle"><a href="#">Level 2</a></div>
        	<div id="level2details">This is a test</div>
  </div>
  <?php
  echo '</div>';
}
?>

Javascript File Code

jQuery(document).ready(function(){
    jQuery('#toggle').click(function(){
    if($jQuery('#level2details').is(':visible')) {
      jQuery('#level2details').hide();
    } else {
      jQuery('#level2details').show();
    }
  });
});

I realize I have a few errors in the above code. I fixed them and basically had to manually load a copy of jQuery by manipulating the admin-header.php file. I haven’t came across any problems where there is a conflict with other things automatically loaded by Wordpress yet. Still, this isn’t the correct way and I’m curious why when I use the NoConflict jQuery that comes with Wordpress by default why it doesn’t work.

Oh well, at least I can keep moving forward!
