Active tags crashes on commas

I added commas using jQuery and CSS.

jQuery(document).ready(function($) {
	var regex = new RegExp('^node-page-');
	$('.node-page').each(function(){
		if(regex.test($(this).attr('id'))){
			var text = $(this).attr('id');
			var num = text.slice(10,14);		
			$('#node-page-'+num+' .field-name-field-tags a') .addClass('commas');
			$('#node-page-'+num+' .field-name-field-tags a:last').removeClass('commas');
		}
	});
});

CSS

.commas:after{content:",";}

To separate tags by commas, just replace the activeTags.addTerm function by the following function:

activeTags.addTerm = function (context, term) {
  // Hide the autocomplete drop down.
  $('#autocomplete').each(function () {
    this.owner.hidePopup();
  });

  // Removing all HTML tags. Need to wrap in tags for text() to work correctly.
  term = $('<div>' + term + '</div>').text();
  term = Drupal.checkPlain(term);
  term = jQuery.trim(term);

  if (term != '') {
	  var terms = term.split(',');
	  for (var i = 0; i < terms.length; i++){
	    var termDiv = $(context);
	    var termList = termDiv.parent().find('.at-term-list');
	    termList.append(Drupal.theme('activeTagsTermRemove', terms[i]));
	  }
    // Attach behaviors to new DOM content.
    Drupal.attachBehaviors(termList);
    activeTags.updateFormValue(termList);
    termList.parent().find('.at-term-entry').val('');
  }

  return false;
};
