复制代码 代码如下:

var restrictX;

var restrictY;

var tip;

// 鼠标坐标

function mousePosition(ev) {

return {

x : ev.clientX + document.documentElement.scrollLeft - document.documentElement.clientLeft,

y : ev.clientY + document.documentElement.scrollTop - document.documentElement.clientTop

};

}

// 鼠标事件

function mouseMove(ev) {

ev = ev || window.event;

var mousePos = mousePosition(ev);

restrictX = mousePos.x;

restrictY = mousePos.y;

}

document.onmousemove = mouseMove;

document.onclick = mouseMove;

上面的代码在谷歌和搜狐浏览器中获取的值会不准确，需进行修改，如下：

复制代码 代码如下:

var restrictX;

var restrictY;

var tip;

// 鼠标坐标

function mousePosition(ev){

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

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

return {

x:ev.clientX + scrollLeft - document.documentElement.clientLeft,

y:ev.clientY + scrollTop - document.documentElement.clientTop

};

}

// 鼠标事件

function mouseMove(ev){

ev = ev || window.event;

var mousePos = mousePosition(ev);

restrictX = mousePos.x;

restrictY = mousePos.y;

}

document.onmousemove = mouseMove;

document.onclick = mouseMove;

复制代码 代码如下:

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

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

这两句为，如果能获取到鼠标坐标，则去前面，否则用后面的方法获取鼠标坐标，“|| ”后面的是给WebKit 内核的浏览器使用
