Add delay to mouseleave in jquery

Question

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))
                })

Answer 1

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.

Answer 2

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)
});
