jQuery check hover status before start trigger

问题

i create a small slider plugin with jquery. the images would slide 5% in from left or right when the mouse is over the left or right controll div. On click the image slides in to 100%

the problem is that when move the mouse during the full slide in animation from the left to right control div i coudnt check if the mouse is always over the left div to trigger the mouseover event again. the result is that the image from the left and the from the right is show 5%.

Is there a way to check the mouseover like this one?

if($(this).mouseover())
$(".right").trigger("mouseover");

the code of a controller div look like this

        $(".right",this).bind({
            mouseover:function(){
                if( vars.current == $("img").length-1 || vars.running) return false;
                $("img:eq("+(vars.current+1)+")").removeAttr("style").css({position:"absolute",left:"100%","z-index":vars.current+1}).show().animate({left:"95%"}, {queue: false})
            },
            mouseleave:function(){
                if( vars.current == $("img").length-1 || vars.running) return false;
                $("img:eq("+(vars.current+1)+")").animate({left:"100%"}, {queue: false , complete:function(){ $(this).hide() } });
            },
            click:function(){
                if( vars.current == $("img").length-1 || vars.running) return false;
                vars.running = true;
                $("img:eq("+(vars.current+1)+")").animate({left:"0%"}, {queue: false, complete:function(){ 
                    $("img:eq("+vars.current+")").hide(); 
                    $(this).css({"z-index":0})
                    vars.current++;
                    vars.running = false;
                    if($(this).mouseover())
                    $(".right").trigger("mouseover");
                } } );
            }
        })

i use the way from the other answer... but its deletet....

mouseover:function(){
                isOver = 'right';
                if( vars.current == $("img").length-1 || vars.running) return false;
                $("img:eq("+(vars.current+1)+")").removeAttr("style").css({position:"absolute",left:"100%","z-index":vars.current+1}).show().animate({left:"95%"}, {queue: false})
            },
            mouseleave:function(){
                isOver = false
                if( vars.current == $("img").length-1 || vars.running) return false;
                $("img:eq("+(vars.current+1)+")").animate({left:"100%"}, {queue: false , complete:function(){ $(this).hide() } });
            },
            click:function(){
                if( vars.current == $("img").length-1 || vars.running) return false;
                vars.running = true;
                $("img:eq("+(vars.current+1)+")").animate({left:"0%"}, {queue: false, complete:function(){ 
                    $("img:eq("+vars.current+")").hide(); 
                    $(this).css({"z-index":0})
                    vars.current++;
                    vars.running = false;
                    if(isOver)
                    $("."+isOver).trigger("mouseover");
                } } );
            }

by using the var isOver i could trigger the left or right

To check whether something is being hovered, you can use the :hover selector, e.g.:

$('#test').click(function() {
    if ($('#hello').is(':hover')) {
        alert('hello');
    }
});

actionshrimp's answer is broken as of jQuery 1.9.1.

Use instead

$("#idOfYourElement:hover").length > 0

in your if condition
