获取鼠标相对于放置的div的位置

Question

I can get the absolute position of the mouse with:

$(document).mousemove(function(e) {
        window.x = e.pageX;
        window.y = e.pageY;
    });

How can I get this position relative to a specific div?

Answer 1

You can use the offset of the div :

$(document).mousemove(function(e) {
    var offset = $(yourdiv).offset();
    window.x = e.pageX - offset.left;
    window.y = e.pageY - offset.top;
});

Answer 2

只需从div的offsetLeft和offsetTop中减去clientX和ClientY
