JavaScript怎么获得鼠标当前坐标？

1、屏幕位置

function getMousePos(event) {

var e = event || window.event;

return {'x':e.screenX,'y':screenY}

}

2、浏览器窗口

function getMousePos(event) {

var e = event || window.event;

return {'x':e.clientX,'y':clientY}

}

3、文档

function getMousePos(event) {

var e = event || window.event;

var scrollX = document.documentElement.scrollLeft || document.body.scrollLeft;

var scrollY = document.documentElement.scrollTop || document.body.scrollTop;

var x = e.pageX || e.clientX + scrollX;

var y = e.pageY || e.clientY + scrollY;

//alert('x: ' + x + '\ny: ' + y);

return { 'x': x, 'y': y };

}
