如何设置时间限制

Question

我想时间限制添加到Javascript代码，

你能不能帮我修改，

详情： 有一个按钮，鼠标将遵循这个按钮，我想要做的是鼠标将不会在x秒后的按钮。

下面是代码：

<script> 
var iflag = 0; 
var icontainer = document.getElementById('icontainer');  
var standardbody=(document.compatMode=="CSS1Compat")? document.documentElement : document.body 



function mouseFollower(e){ 
if (window.event) 
{ // for IE 
    icontainer.style.top = (window.event.y-5)+standardbody.scrollTop+'px'; 
    icontainer.style.left = (window.event.x-5)+standardbody.scrollLeft+'px'; 
} 
else 
{ 
    icontainer.style.top = (e.pageY-5)+'px'; 
    icontainer.style.left = (e.pageX-5)+'px'; 
} 

} 
document.onmousemove = function(e) { 
    if (iflag == 0) {mouseFollower(e);} 
} 

</script> 

Answer 1

var startTime = null; //we haven't started yet 
var limit = 10000; //10 seconds 

document.onmousemove = function(e) { 
    var now = new Date(); 

    // set startTime to now if this is the first run i.e. it doesn't have a value 
    // so we can tell when we started 
    var startTime = startTime || now; 

    // if we've been running longer than limit 
    if (now >= startTime + limit) { //using a Date as a scalar gets a timestamp 
     // delete this function so it can't run again 
     delete document.onmousemove; 
    } else { 
     // do following stuff 
     mouseFollower(e); 
    } 
}
