    <title>无标题文档</title>
    <script>
    var a={"code":1,"list":[{"category1_id":"1","category1_name":"u9152u6c34u996eu6599","category1_intro":"u6e05u51c9u53efu53e3u7684u9152u6c34u996eu6599","category1_images":"http://www.songcuomen.com/attachments/productType/2014-01/10/21_1389343628.jpg"},{"category1_id":"2","category1_name":"u7c73u9762u7caeu6cb9","category1_intro":"u5bb6u5eadu5fc5u5907","category1_images":"http://www.songcuomen.com/attachments/productType/2014-01/10/21_1389343865.jpg"},{"category1_id":"3","category1_name":"u7f8eu5bb9u6d17u62a4","category1_intro":"u62a4u80a4u5fc5u5907","category1_images":"http://www.songcuomen.com/attachments/productType/2014-01/10/21_1389343935.jpg"},{"category1_id":"4","category1_name":"u6e05u6d01u6d17u6da4","category1_intro":"u7ed9u60a8u4e00u4e2au5e72u51c0u7684u751fu6d3bu73afu5883","category1_images":"http://www.songcuomen.com/attachments/productType/2014-01/10/21_1389343986.jpg"},{"category1_id":"5","category1_name":"u751fu6d3bu7528u54c1","category1_intro":"u5bb6u5eadu5fc5u5907","category1_images":"http://www.songcuomen.com/attachments/productType/2014-01/10/21_1389344445.jpg"},{"category1_id":"6","category1_name":"u4f11u95f2u98dfu54c1","category1_intro":"u597du5403u7f8eu5473","category1_images":"http://www.songcuomen.com/attachments/productType/2014-01/10/21_1389344494.jpg"}]};
    var y=1;//表示页数
    var t=2;//表示每页现实几条数据
    var z=a["list"].length;
    var zy= Math.ceil(z/t);
    window.onload=function (){
    fanye(0);
    }
    function fanye(f)
    {
        if(y==1 && f==-1)
        {
            alert('已经是第一页了');
            f=0;
            }
        if(y==zy && f==1)
        {
            alert('已经是最后一页了');
            f=0;
            }    
        
         var otbod=document.getElementById('table').tBodies[0];
         var s=otbod.rows.length;
        for(i=0;i<s;i++)
        {
        
            otbod.removeChild(otbod.rows[0]);
        }
            y+=f;
           var q=(y-1)*2;//页数-1 乘以每页现实多少条 结果为 本页从第几条开始
           for(var i=1;i<3;i++)
        {
            
        var otr=document.createElement('tr');
        var otd1=document.createElement('td');
        var otd2=document.createElement('td');
        var otd3=document.createElement('td');
        var otd4=document.createElement('td');
        otd1.innerHTML=a["list"][q]['category1_id'];
        otd2.innerHTML=a["list"][q]['category1_name'];
        otd3.innerHTML=a["list"][q]['category1_intro'];
        otd4.innerHTML=a["list"][q]['category1_images'];
        otr.appendChild(otd1);
        otr.appendChild(otd2);
        otr.appendChild(otd3);
        otr.appendChild(otd4);
         otbod.appendChild(otr);
         if(q==zy)
         {
             break;
             }
        q++;
        }
    }
    </script>
    
    </head>
    
    <body>
    
    <table  border="1" id="table">
    <thead>
    <tr><td>category1_id</td><td>category1_name</td><td>category1_intro</td><td>category1_images</td></tr>
    </thead>
    <tbody>
