　　　　　　　　　 // 如果采用下面这种方式，会出现多次绑定，多次查询的情况。
                //obj.on("click","a.tcdNumber",function(){
                //    var current = parseInt($(this).text());

2、使用方法

2.1 js的应用

首先把jquery.page.js引入

第二js的关键代码

$(".tcdPageCode").createPage({
　　pageCount: 总页数,
　　current: 当前页,
　　backFn: function (p) {
　　　　//单击回调方法，p是当前页码
　　　　查询方法(p);
　　}
});

2.2 样式代码

.tcdPageCode {
    padding: 15px 20px;
    color: #ccc;
    display: inline-block;
    padding-left:;
    margin: 20px 0;
    border-radius: 4px;
}

    .tcdPageCode a {
        display: inline-block;
        color: #0D0D0D;
        display: inline-block;
        height: 25px;
        line-height: 25px;
        padding: 6px 12px;
        border: 1px solid #ddd;
        vertical-align: middle;
        padding: 6px 12px;
        line-height: 1.42857143;
        text-decoration: none;
    }

    .tcdPageCode span.current {
        display: inline-block;
        height: 25px;
        line-height: 25px;
        padding: 6px 12px;
        color: #0D0D0D;
        background-color: #CCCCCC;
        border: 1px solid #ddd;
        vertical-align: middle;
        line-height: 1.42857143;
        text-decoration: none;
    }

.tcdPageCode-ellipsis {
    display: inline-block;
    width: 24px;
    text-align: center;
}

.tcdPageCode span.disabled {
    display: inline-block;
    height: 25px;
    line-height: 25px;
    padding: 6px 12px;
    color: #bfbfbf;
    background: #f2f2f2;
    border: 1px solid #bfbfbf;
    border-radius: 4px;
    vertical-align: middle;
}
