jquery tooltip hover help

Question

I have a tooltip pulling in some Ajax content and want the tooltip to stay visible when the user hovers over the tooltip not just the original link.

How would I achieve this extending the following code

(function($){ $.fn.tooltip = function(options){

var defaults = {
    cssClass: "",     //CSS class or classes to style the tooltip
    delay : 0,        //The number of milliseconds before displaying the tooltip
    duration : 500,   //The number of milliseconds after moving the mouse cusor before removing the tooltip.
    xOffset : 15,     //X offset will allow the tooltip to appear offset by x pixels.
    yOffset : 15,     //Y offset will allow the tooltip to appear offset by y pixels.
    opacity : 0,      //0 is completely opaque and 100 completely transparent
    fadeDuration: 400, //[toxi20090112] added fade duration in millis (default = "normal")
    fixed: false
};

var options = $.extend(defaults, options);


return this.each(function(index) {


    var $this = $(this);

    //use just one div for all tooltips
    // [toxi20090112] allow the tooltip div to be already present (would break currently)
    $tooltip=$("#divTooltip");
    if($tooltip.length == 0){
        $tooltip = $('<div id="divTooltip"></div>');            
        $('body').append($tooltip);
        $tooltip.hide();
    }

    //displays the tooltip
    $this.mouseover( function(e){
        //compatibility issue
        e = e ? e : window.event;

        //don't hide the tooltip if the mouse is over the element again
        clearTimeout($tooltip.data("hideTimeoutId"));

        //set the tooltip class
        $tooltip.removeClass($tooltip.attr("class"));
        $tooltip.css("width","");
        $tooltip.css("height","");
        $tooltip.addClass(options.cssClass);
        $tooltip.css("opacity",1-options.opacity/100);
        $tooltip.css("position","absolute");            

        //save the title text and remove it from title to avoid showing the default tooltip
        $tooltip.data("title",$this.attr("title"));
        $this.attr("title","");
        $tooltip.data("alt",$this.attr("alt"));
        $this.attr("alt","");

        //set the tooltip content
        $tooltip.html($tooltip.data("title"));
        // [toxi20090112] only use ajax if there actually is an href attrib present
        var href=$this.attr("href");
        // [Peter] href!="" added
        if(href!=undefined && href!="" && href != "#")
            $tooltip.html($.ajax({url:$this.attr("href"),async:false}).responseText);

        if(options.fixed === false){
            //set the tooltip position
            winw = $(window).width();
            w = $tooltip.width();
            xOffset = options.xOffset;

            //right priority
            if(w+xOffset+50 < winw-e.clientX)
              $tooltip.css("left", $(document).scrollLeft() + e.clientX+xOffset);
            else if(w+xOffset+50 < e.clientX)
              $tooltip.css("left", $(document).scrollLeft() + e.clientX-(w+xOffset));
            else{
              //there is more space at left, fit the tooltip there
              if(e.clientX > winw/2){
                $tooltip.width(e.clientX-50);
                $tooltip.css("left", $(document).scrollLeft() + 25);
              }
              //there is more space at right, fit the tooltip there
              else{
                $tooltip.width((winw-e.clientX)-50);
                $tooltip.css("left", $(document).scrollLeft() + e.clientX+xOffset);
              }
            }

            winh = $(window).height();
            h = $tooltip.height();
            yOffset = options.yOffset;
            //top position priority
            if(h+yOffset + 50 < e.clientY)
              $tooltip.css("top", $(document).scrollTop() + e.clientY-(h+yOffset));
            else if(h+yOffset + 50 < winh-e.clientY)
              $tooltip.css("top", $(document).scrollTop() + e.clientY+yOffset);
            else 
              $tooltip.css("top", $(document).scrollTop() + 10);
        }

        //start the timer to show the tooltip
        //[toxi20090112] modified to make use of fadeDuration option
        $tooltip.data("showTimeoutId", setTimeout("$tooltip.fadeIn("+options.fadeDuration+")",options.delay));
    });

    $this.mouseout(function(e){
        //restore the title
        $this.attr("title",$tooltip.data("title"));
        $this.attr("alt",$tooltip.data("alt"));
        //don't show the tooltip if the mouse left the element before the delay time
        clearTimeout($tooltip.data("showTimeoutId"));
        //start the timer to hide the tooltip
        //[toxi20090112] modified to make use of fadeDuration option
        $tooltip.data("hideTimeoutId", setTimeout("$tooltip.fadeOut("+options.fadeDuration+")",options.duration));
    });

    $this.click(function(e){
        e.preventDefault();
    });

});

}})(jQuery);
