本文實例講述了JS實現仿中關村論壇評分後彈出提示效果的方法。分享給大家供大家參考。具體實現方法如下：
複製代碼代碼如下:<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script language="javascript">
var x=window.x||{};
x.creat=function(t,b,c,d){
this.t=t;
this.b=b;
this.c=c;

this.op=1;
this.div=document.createElement("div");
this.div.style.height="40px";

this.div.innerText="謝謝參與！經驗+5"

this.div.style.lineHeight=this.div.style.height
this.div.style.textAlign="center";
this.div.style.fontWeight="bold";
//this.div.style.border="solid red 1px";
this.div.style.color="#fff"
this.div.style.top=(this.b+"%");
document.body.appendChild(this.div);
this.run();
}
x.creat.prototype={
run:function(){
var me=this;
this.div.style.top=-this.c*(this.t/this.d)*(this.t/this.d)+this.b+"%";
this.t++;
this.q=setTimeout(function(){me.run()},25)
if(this.t==this.d){
clearTimeout(me.q);
setTimeout(function(){me.alpha();},1000);
}
},
alpha:function(){
var me=this;
if("/v"=="v"){
this.div.style.filter="progid:DXImageTransform.Microsoft.Alpha(opacity="+this.op*100+")";
this.div.style.filter="alpha(opacity="+this.op*100+")";
;}
else{this.div.style.opacity=this.op}
this.op-=0.02;
this.w=setTimeout(function(){me.alpha()},25)
if(this.op<=0){
clearTimeout(this.w);
document.body.removeChild(me.div);
}
}
}
new x.creat(1,50,25,30);
