復制代碼 代碼如下:
var restrictX; 
var restrictY; 
var tip; 
// 鼠標坐標  
function mousePosition(ev) { 
return { 
        x : ev.clientX + document.documentElement.scrollLeft - document.documentElement.clientLeft, 
        y : ev.clientY + document.documentElement.scrollTop - document.documentElement.clientTop 
    }; 
} 
// 鼠標事件  
function mouseMove(ev) { 
    ev = ev || window.event; 
    var mousePos = mousePosition(ev); 
    restrictX = mousePos.x; 
    restrictY = mousePos.y; 
} 
document.onmousemove = mouseMove; 
document.onclick = mouseMove; 

上面的代碼在谷歌和搜狐浏覽器中獲取的值會不准確，需進行修改，如下：
復制代碼 代碼如下:
var restrictX; 
var restrictY; 
var tip; 
// 鼠標坐標  
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 
    }; 
} 
// 鼠標事件  
function mouseMove(ev){ 
    ev = ev || window.event; 
    var mousePos = mousePosition(ev); 
    restrictX = mousePos.x; 
    restrictY = mousePos.y; 
} 
document.onmousemove = mouseMove; 
document.onclick = mouseMove; 

復制代碼 代碼如下:
var scrollLeft = document.documentElement.scrollLeft || document.body.scrollLeft;
var scrollTop = document.documentElement.scrollTop || document.body.scrollTop; 

這兩句為，如果能獲取到鼠標坐標，則去前面，否則用後面的方法獲取鼠標坐標，“|| ”後面的是給WebKit 內核的浏覽器使用
