本文实例讲述了JS封装的模仿qq右下角消息弹窗功能。分享给大家供大家参考，具体如下：
在我们的日常开发中，或者生活中，经常需要用到弹出窗。这里我们就用js模拟一下qq消息一样的弹出窗。
直接贴代码：

<body>
<script type="text/javascript">
var ShowMsg={
title:'提示',
content:'模拟qq弹出框消息提醒',
width:'300px',
height:'100px',
setTitle:function(value){
this.title=value;
},
setContent:function(value){
this.content=value;
},
getTitle:function(){
return this.title;
},
getContent:function(){
return this.content;
},
show:function(){
//弹窗div
var _winPopDiv = document.createElement('div');
_winPopDiv.id="_winPopDiv";
_winPopDiv.style.cssText = 'width:300px; position:absolute; right:0; bottom:0; border:1px solid #666; margin:0; padding:1px; overflow:hidden; display:block;';
//消息标题div
var _titleDiv= document.createElement('div');
_titleDiv.id="_titleDiv";
_titleDiv.innerHTML=this.getTitle();
_titleDiv.style.cssText = 'width:100%; height:22px; line-height:20px; background:#FFCC00; font-weight:bold; text-align:left; font-size:14px;';
_winPopDiv.appendChild(_titleDiv);
//关闭消息按钮span
var _closeSpan= document.createElement('span');
_closeSpan.id="_closeSpan";
_closeSpan.innerHTML="X";
_closeSpan.style.cssText = 'position:absolute; right:4px; top:-1px; color:#FFF; cursor:pointer;font-size:14px;';
_titleDiv.appendChild(_closeSpan);
//内容div
var _conDiv= document.createElement('div');
_conDiv.id="_conDiv";
_conDiv.style.cssText = 'width:100%; height:110px; line-height:80px; font-weight:bold; font-size:12px; color:#FF0000; text-decoration:underline; text-align:center;';
_conDiv.innerHTML=this.getContent();
_winPopDiv.appendChild(_conDiv);
document.body.appendChild(_winPopDiv);
//关闭span绑定事件
var closeDiv = document.getElementById("_closeSpan");
if(closeDiv.addEventListener){
closeDiv.addEventListener("click",function(e){
if (window.event != undefined) {
window.event.cancelBubble = true;
} else if (e.stopPropagation) {
e.stopPropagation();
}
document.getElementById('_winPopDiv').style.cssText="display:none;";
},false);
}else if(closeDiv.attachEvent){
closeDiv.attachEvent("onclick",function(e){
if (window.event != undefined) {
window.event.cancelBubble = true;
} else if (e.stopPropagation) {
e.stopPropagation();
}
document.getElementById('_winPopDiv').style.cssText="display:none;";
});
}
}
};
ShowMsg.show();
</script>
</body>
</html>
这里使用在线HTML/CSS/JavaScript代码运行工具：http://tools.3water.com/code/HtmlJsRun，测试可得到如下运行效果：
希望本文所述对大家JavaScript程序设计有所帮助。
