jquery 地图交互式鼠标悬停名称已移动

Question

我会证明是清楚的。我有一个交互式地图，如果我将鼠标放在每个区域上，该区域的名称就会出现在我的鼠标上。没问题。问题是当我进入我的页面时（所以页面一定很长）。如果我将鼠标移到每个区域（我仍然可以看到），名称会发生变化，他太低了，而不是在我的鼠标上。我希望已经清楚了。如何解决问题？

Answer 1

这是您需要的：top:e.pageY-$('#map #tooltip').height()-20 - $(document).scrollTop()

$(document).mousemove(function(e){
    $('#map #tooltip').css({
        top:e.pageY-$('#map #tooltip').height()-20 - $(document).scrollTop(),
        left:e.pageX-$('#map #tooltip').width()/2-10,
    });
});
