请尝试下面的代码也许它会给你一个想法,我尝试做一个我在评论中描述的演示。请将jquery.min.js文件放在工作区中。

notification.html

<html>
        <head>
            <script src="jquery.min.js"></script>
            <link rel="stylesheet" type="text/css" href="style.css">
        </head>
        <body>
        <form method="POST">
            <a href="" id="notification"  class="badge" data-badge="0">Badge Notification Example</a>
            <input id="submit" value="Push" class="submit" onclick="push();"  type="button"></input>
            <input id="submit" value="Pop" class="submit" onclick="pop();"  type="button"></input>
        </form>
       </body>
    <script>
        function push(){
            var notification=$("#notification").attr("data-badge");
            var counter =parseInt(notification,10);
            if(counter>9){
                alert("Notification list is full!");
                return;     
            }
            counter=counter+1;      
            $("#notification").attr("data-badge",counter);
        }
        function pop(){
            var notification=$("#notification").attr("data-badge");
            var counter=parseInt(notification,10);
            if(counter<1){
                alert("list is empty!");
                return;     
            }
            counter=counter-1;
            $("#notification").attr("data-badge",counter);
        } 
    </script>
     </html>

的style.css

.badge{
    position:relative;
}
    .badge[data-badge]:after {
    content:attr(data-badge);
    position:absolute;
    top:-10px;
    right:-10px;
    font-size:.7em;
    background:green;
    color:white;
        width:18px;
    height:18px;
        text-align:center;
        line-height:18px;
        border-radius:50%;
    box-shadow:0 0 1px #333;
}
.submit{
    margin-top    : 20px;
        margin-right  : 10px;
        margin-bottom : 20px;
        margin-left   : 10px;
    font-size:100m;
    background:orange;
    color:green;
        width:150px;
    height:30px;
        text-align:center;          
}
