记录鼠标的轨迹并回放的js代码_javascript技巧

//延迟方法
sleep: function(n) {
var start = new Date().getTime();
while (true)
if (new Date().getTime() - start > n)
break;
},
//回看轨迹记录
backTrack: function() {
var oSlippage = document.getElementById("slippage");
var len = this.X.length;
for (var i = 0; i oSlippage.style.left = this.X[i] - this.relativeX;
oSlippage.style.top = this.Y[i] - this.relativeY;
//延迟循环方法
this.sleep(10);
}
}

//延迟方法
sleep: function(n) {
//var start = new Date().getTime();
//while (true)
// if (new Date().getTime() - start > n)
// break;
var oSlippage = document.getElementById("slippage");
oSlippage.style.left = this.X[this.iNum] - this.relativeX; //iNum为数组下标
oSlippage.style.top = this.Y[this.iNum] - this.relativeY;
MOUSETRACKRECORD.iNum++;
//如果下标大于了他的长度就停止回放
if (this.iNum > this.X.length - 1) {
clearInterval(this.timeID);
