asp.net实现MSN弹出窗口特效

来源：互联网发布：淘宝花溪折扣店怎么样编辑：程序博客网时间：2024/05/16 08:39

最近因为有一个项目，要做这样一个功能，是用户登录以后。如果用户有新消息。那么就在右下角出现一个窗口来提示用户有新消息。
在网上找了一下这方面的资料，发现很多都是用popwind这个控件。自己也下了一下。可能是我的外语不好。使用了一下，感觉不是很方便，就没有用。而且找了一下有没有这方面的javascript代码。还真找到了一下比较不错的。是ttyp写的。就在它的基础上我进行修改。来完成我的需要。不多说了，下面是代码。

<!-- 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);

me.Pop.hide();

} else {

me.offset = me.offset - me.step;

}

me.Pop.show(x,y,width,height);

}

this.timer = window.setInterval(fun,this.speed)

if(i==1)//这里是做一个判断用来判断用户是否有新的消息

{

}

//同时两个有闪烁，只能用层代替了，不过层不跨框架

//var MSG2 = new CLASS_MSN_MESSAGE("aa",200,120,"短消息提示：","您有2封消息","好的啊");

// MSG2.rect(100,null,null,screen.height);

// MSG2.show();

//-->

</SCRIPT>

</head>

<body>

<div>

</div>

</form>

</body>

</html>

这是前台页面。
后台页面就简单多了，我只是做了一个简单的判断。没有做数据库的链接判断。

public static int i = 0;//这里定义一个静态变量用来存储状态值的。因为做为静态处理，你在前台页面可以使用它。

protected void Page_Load(object sender, EventArgs e)

{

i = 2;

}

好了，看一下效果吧。应该还是不错的。
