I would like to add an onclick event to the Opencart filters to replace the submit button which is hidden off the page.. I am presuming that this should be done with javascript/jquery, but implementation is a little beyond me, can you help?

PHP:

<div class="box">
 <div class="box-heading"><?php echo $heading_title; ?></div>
 <div class="box-content">
  <ul class="box-filter">
   <?php foreach ($filter_groups as $filter_group) { ?>
   <li><span id="filter-group<?php echo $filter_group['filter_group_id']; ?>"><?php echo $filter_group['name']; ?></span>
    <ul>
     <?php foreach ($filter_group['filter'] as $filter) { ?>
     <?php if (in_array($filter['filter_id'], $filter_category)) { ?>
     <li>
      <input type="checkbox" value="<?php echo $filter['filter_id']; ?>" class="click_checkbox_manufacturers-filter" id="filter<?php echo $filter['filter_id']; ?>" checked="checked" />
      <label for="filter<?php echo $filter['filter_id']; ?>"><?php echo $filter['name']; ?></label>
     </li>
     <?php } else { ?>
     <li>
      <input type="checkbox" value="<?php echo $filter['filter_id']; ?>" class="click_checkbox_manufacturers-filter" id="filter<?php echo $filter['filter_id']; ?>" />
      <label for="filter<?php echo $filter['filter_id']; ?>"><?php echo $filter['name']; ?></label>
     </li>
     <?php } ?>
     <?php } ?>
    </ul>
   </li>
   <?php } ?>
  </ul>
  <a id="button-filter" class="button"><?php echo $button_filter; ?></a>
 </div>
</div>

HTML OUTPUT:

<div class="box">
 <div class="box-heading">Refine Search</div>
 <div class="box-content">
  <ul class="box-filter">
   <li><span id="filter-group2">Colour</span>
   <ul>

     </li>
     <li>
      <input type="checkbox" value="65" class="click_checkbox_manufacturers-filter" id="filter65">
      <label for="filter65">Coconut</label>
     </li>
    </ul>
   </li>
  </ul>
  <a id="button-filter" class="button">Refine Search</a>
 </div>
</div>

JavaScript

<script type="text/javascript">
$('#button-filter').bind('click', function() {
    filter = [];

    $('.box-filter input[type=\'checkbox\']:checked').each(function(element) {
        filter.push(this.value);
    });

    location = '<?php echo $action; ?>&filter=' + filter.join(',');
});

You can do something like this (instead of the current script):

<script type="text/javascript">
$(document).ready(function() {
    // hide the "submit" button
    $('#button-filter').hide();

    // bind onChange event to the checkboxes
    $('.click_checkbox_manufacturers-filter').live('change', function() {
        filter = [];

        $('.box-filter input[type=\'checkbox\']:checked').each(function(element) {
            filter.push(this.value);
        });

        window.location = '<?php echo $action; ?>&filter=' + filter.join(',');
    });
});
//--></script>

Here is link to my JsFiddle of the very same JS code, which, surprisingly is working. The only issue may be with redirect... I edited the redirect code above so it should work as well.

For version 2 change the JavaScript in the filter.tpl file (from catalog/view/theme/default/template/extension/module/filter.tpl - change 'default' to your theme name if necessary) to this

<script type="text/javascript">
     $(document).ready(function() {
        $('#button-filter').hide();

        $('input[name^=\'filter\']').on('change', function() {
           filter = [];

            $('input[name^=\'filter\']:checked').each(function(element) {
               filter.push(this.value);
        });

        location = '<?php echo $action; ?>&filter=' + filter.join(',');
     });
});
</script>

Tested in OC 2.3.0.2.
