on a moving element don't fire the mouse events

问题

a tooltip will show when mouse over a moving div, but ,the div is moving,it doesn't fire the mouse events,see the problem: http://jsfiddle.net/jcezG/6/ (firefox 23.0.1 is ok). `

$('.area').on('mouseenter',function(){
    $('.tooltip').show();
}).on('mouseleave',function(){
    $('.tooltip').hide();
});
var offset = 10;
setInterval(function(){
    //$('.area').hide();
    $('.area').css({"-webkit-transform":"translate("+offset+"px,"+offset+"px)"});
    //$('.area').css({"left":offset+'px',"top":offset+'px'});
    offset += 10;
},1000);

forgive my poor english.

回答1:

can you please replace your code with this

and set left and top postion at time of mouseover

$('.area').on('mouseenter',function(){
     $('.tooltip').show();
}).on('mousemove', function(e){
     $('.tooltip').css({'top':e.pageY,'left':e.pageX});
}).on('mouseleave',function(){
     $('.tooltip').hide();
});

and set z-index:100; in tooltip class

回答2:

$('.area').on('mouseenter',function(){
    $('.tooltip').show();
}).on('mousemove', function(e){
   $('.tooltip').css({'top':e.pageY,'left':e.pageX, 'z-index':'1'});
}).on('mouseleave',function(){
    $('.tooltip').hide();
});

var offset = 10;
setInterval(function(){
    //$('.area').hide();
    $('.area').css({"-webkit-transform":"translate("+offset+"px,"+offset+"px)","-moz-transform":"translate("+offset+"px,"+offset+"px)"});
    //$('.area').css({"left":offset+'px',"top":offset+'px'});
    offset += 10;
},1000);

Check this line "$('.area').css({"-webkit-transform":"translate("+offset+"px,"+offset+"px)","-moz-transform":"translate("+offset+"px,"+offset+"px)"}); //$('.area').css({"left":offset+'px',"top":offset+'px'});" Is that the way you want ? check the fiddle JSFiddle

回答3:

you have to use the div position as well as mouse pointer position and fire same effect on mouseenter and mousemove to get the latest position of mouse pointer.

var x,y;

$('.area').on('mouseenter mousemove',function(e){
    //console.log(e.pageX + "|" + e.pageY);
    x= e.pageX;
    y=e.pageY;
    $('.tooltip').css({'top':e.pageY,'left':e.pageX + 15, 'z-index':'1'}).show();
}).on('mouseleave',function(){
    $('.tooltip').hide();
});
