Add delay to mouseleave in jquery

I'm using this code in my site and I was wondering how I could add a delay to the mouseleave function

$target.mouseenter(function(e){
                var $tooltip=$("#"+this._tipid)
                ddimgtooltip.showbox($, $tooltip, e)
            })
            $target.mouseleave(function(e){
             var $tooltip=$("#"+this._tipid);
             setTimeout(function() { ddimgtooltip.hidebox($, $tooltip); }, 4000);
            })

            $target.mousemove(function(e){
                var $tooltip=$("#"+this._tipid)
                ddimgtooltip.positiontooltip($, $tooltip, e)
            })
            if ($tooltip){ //add mouseenter to this tooltip (only if event hasn't already been added)
                $tooltip.mouseenter(function(){
                    ddimgtooltip.hidebox($, $(this))
                })

You can use this function I just wrote:

$.fn.hoverDelay = function(handlerIn, handlerOut, delay) {
    if(delay === undefined) delay = 400;
    var timer;
    this.hover(function(eventObject) {
        clearTimeout(timer);
        handlerIn.apply(this,eventObject);
    }, function(eventObject) {
        timer = setTimeout(handlerOut.bind(this, eventObject), delay);
    });
};

It works just like the normal $.hover except there is a 400ms delay before the mouse leave event is called (which is cancelled if you move your mouse back in within that timeframe).

(function($){
   $.fn.lazybind = function(event, fn, timeout, abort){
        var timer = null;
        $(this).bind(event, function(){
            timer = setTimeout(fn, timeout);
        });
        if(abort == undefined){
            return;
        }
        $(this).bind(abort, function(){
            if(timer != null){
                clearTimeout(timer);
            }
        });
    };
})(jQuery);


$('#tooltip').lazybind(
    'mouseout',
    function(){
        $('#tooltip').hide();
    },
    540,
    'mouseover');

The problem with just a timer would be if you mouse left and then re-entered it would still hide after that timer completed. Something like the following might work better because we can cancel the timer whenever the mouse enters the target.

var myTimer=false;
$target.hover(function(){
    //mouse enter
    clearTimeout(myTimer);
},
function(){
    //mouse leave
    var $tooltip=$("#"+this._tipid);
    myTimer = setTimeout(function(){
        ddimgtooltip.hidebox($, $tooltip);
    },500)
});

You can use setTimeout() and an anonymous function for this:

$target.mouseleave(function(e){
 var $tooltip=$("#"+this._tipid);
 setTimeout(function() { ddimgtooltip.hidebox($, $tooltip); }, 250);
})

This would delay it 250ms after leaving before it hides, you can just adjust that value as needed.
