还是在做联通IOM项目时遇到的一个需求,要求页面每隔半小时弹出一次提示消息（消息以类似QQ新闻的形式弹出）。当时上网找的这么一个资料，已经不记得原文出处了
代码如下:
<html>
<head>
<title>JavaScript提示框</title>
<script type="text/javascript">
<!--
/**
* 类名：CLASS_MSN_MESSAGE
* 功能：提供类似MSN消息框
* 示例：
* var MSG = new CLASS_MSN_MESSAGE("aa",200,120,"短消息提示：","您有1封消息","今天请我吃饭哈");
* MSG.show();
* 消息构造
*/
function CLASS_MSN_MESSAGE(id,width,height,caption,title,message,target,action){
this.id = id;
this.title = title;
this.caption = caption;
this.message = message;
this.target = target;
this.action = action;
this.width = width?width:200;
this.height = height?height:120;
this.timeout = 150;
this.speed = 20;
this.step = 1;
this.right = screen.width -1;
this.bottom = screen.height;
this.left = this.right - this.width;
this.top = this.bottom - this.height;
this.timer = 0;
this.pause = false;
this.close = false;
this.autoHide = true;
}
/**
* 隐藏消息方法
*/
CLASS_MSN_MESSAGE.prototype.hide = function(){
if(this.onunload()){
var offset = this.height>this.bottom-this.top?this.height:this.bottom-this.top;
var me = this;
if(this.timer>0){
window.clearInterval(me.timer);
}
var fun = function(){
if(me.pause==false||me.close){
var x = me.left;
var y = 0;
var width = me.width;
var height = 0;
if(me.offset>0){
height = me.offset;
}
y = me.bottom - height;
if(y>=me.bottom){
window.clearInterval(me.timer);
} else {
me.offset = me.offset - me.step;
}
me.Pop.show(x,y,width,height);
}
}
this.timer = window.setInterval(fun,this.speed)
}
}
/**

CLASS_MSN_MESSAGE.prototype.onunload = function() {
return true;
