  Hello All,

  I am relatively new to jquery but I have been charged at work to write a plugin for an AJAX news Ticker.

  I have had problems with the ticker animating. It runs correctly the first three cycles, but then the fourth cycle no longer animates. My code up to this point is here:

  http://aboutbq.com/test/ticker/

  I'm not sure what the issue is. The function which does the animation is still being called because the ajax data continues to be updated. But the animation no longer runs. I suspect there is some kind of memory leak.

  My code looks like this: jQuery.fn.initTicker = function(){ return this.each(function(){ $self = jQuery(this);

                      //find ul width:
                      tickerscrollW = $self.width();
                              jQuery("#ticker").html(tickerscrollW);
                      var parentW = 0;
                      parentW = 500;
                              jQuery("#parent").html(parentW);
                      //alert("Parent Element\n\n#tickerwrapper width: " + parentW);
                      $self.css({
                              position: "relative",
                              left: parentW/2
                      });
                      $self.animate({
                                      left: 0
                              },
                              2000,
                              "linear",
                              function(){
                                      $.get("data.php", function(data){
                                              jQuery("#alertsub").html(data);
                                              $self.find("li").each(function(){
                                                      jQuery(this).html(data);
                                              });
                                      });
                                      $self.ajaxComplete(function(){
                                              $self.initTicker();
                                      });
                              }
                      );
  
      });
  

  }

  /////////////////////////////////////////////////////////////////////////////////////////////////////////// $(function(){ $("#tickerscroll").initTicker(); });

  If anyone can help it would be much appreciated.
