js右下角消息弹窗效果可以快速的让用户注意到网站系统提示的消息，由于是右下角显示的js弹窗消息，所以既美观，又不占位置，用户会习惯性的查看右边的信息，效果非常明显，下面我们来看看这两种js特效吧，是本人专门收藏的。
效果1：类似于qq消息效果，js兼容性很强，适合任何平台。
js代码如下：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<style type="text/css">
#winpop { width:220px; height:0px; position:absolute; right:0; bottom:0; border:1px solid #999999; margin:0; padding:1px; overflow:hidden; display:none; background:#FFFFFF}
#winpop #title {
width:100%; height:20px; line-height:20px;
font-weight:bold; text-align:center; font-size:12px;

}
#winpop #msg{display:block; margin-top:30px; padding:0; text-align:center;}

</style>
<script type="text/javascript">
function tips_pop(){
var MsgPop=document.getElementById("winpop");//获取窗口这个对象,即ID为winpop的对象
var popH=parseInt(MsgPop.style.height);//用parseInt将对象的高度转化为数字,以方便下面比较
if (popH==0){ //如果窗口的高度是0
MsgPop.style.display="block";//那么将隐藏的窗口显示出来
show=setInterval("changeH('up')",2);//开始以每0.002秒调用函数changeH("up"),即每0.002秒向上移动一次
}
else { //否则
hide=setInterval("changeH('down')",2);//开始以每0.002秒调用函数changeH("down"),即每0.002秒向下移动一次
}
}
function changeH(str) {
var MsgPop=document.getElementById("winpop");
var popH=parseInt(MsgPop.style.height);
if(str=="up"){ //如果这个参数是UP
if (popH<=100){ //如果转化为数值的高度小于等于100
MsgPop.style.height=(popH+4).toString()+"px";//高度增加4个象素
}
else{
clearInterval(show);//否则就取消这个函数调用,意思就是如果高度超过100象度了,就不再增长了
}
}
if(str=="down"){
if (popH>=4){ //如果这个参数是down
MsgPop.style.height=(popH-4).toString()+"px";//那么窗口的高度减少4个象素
}
else{ //否则
clearInterval(hide); //否则就取消这个函数调用,意思就是如果高度小于4个象度的时候,就不再减了
MsgPop.style.display="none"; //因为窗口有边框,所以还是可以看见1~2象素没缩进去,这时候就把DIV隐藏掉
}
}
}
window.onload=function(){ //加载
document.getElementById('winpop').style.height='0px';//我不知道为什么要初始化这个高度,CSS里不是已经初始化了吗,知道的告诉我一下
setTimeout("tips_pop()",800); //0.8秒后调用tips_pop()这个函数
}
</script>
<body>
<div id="winpop">
<div id="title"><div id="titlename">您有(请假流程)2条需要审批</div><span class="close" onclick="closemsg()">X</span></div>
<ul id="msg">
<li><a href="#">请假审批流程(1)<a/></li>
</ul>
</div>
</body>
<script>
function closemsg(){
document.getElementById('winpop').style.height='0px';
document.getElementById('titlename').innerText = 'Fred Flinstone';
tips_pop();
}
</script>
</html>效果2：类似于网易新闻，也是非常美观的js效果特效。
