一、获取鼠标坐标
clientX：鼠标到可视区边缘的距离； scrollLeft:滚动条到页面顶端的距离（不可视区的距离）
兼容性写法：
var scrollTop = document.documentElement.scrollTop || document.body.scrollTop; var scrollLeft = document.documentElement.scrollLeft || document.body.scrollLeft;
跟随鼠标移动的divs，代码如下：
<!DOCTYPE html><html><head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title></title> <meta charset="utf-8" /> <style> div { width: 10px; height: 10px; background: #F00; position: absolute; } </style> <script> window.onload = function () { document.onmousemove = function (ev) { var oEvent = ev || event; var scrollTop = document.documentElement.scrollTop || document.body.scrollTop; var scrollLeft = document.documentElement.scrollLeft || document.body.scrollLeft; var oDivs = document.getElementsByTagName("div");
oDivs[0].style.left = oEvent.clientX + scrollLeft + "px"; oDivs[0].style.top = oEvent.clientY + scrollTop + "px";
for (var i = oDivs.length - 1; i > 0; i--) { oDivs[i].style.left = oDivs[i - 1].style.left; oDivs[i].style.top = oDivs[i - 1].style.top; } }
} </script></head><body> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div> <div></div></body></html>
