jsp页面ajax返回list（里面放有对象）进行循环并插入table

table：

<table width="100%" cellpadding="0" cellspacing="0" border="0" class="memb-table"id="datas">
</table>

ajax:

<script type="text/javascript">
function searchSource(){

      //获取搜索框里的值
var keyWord=$('#keyWord').val();
var typeSource = $('#typeSource option:selected').val();
//循环数据前先删除table的所有行
var tb = document.getElementById('datas');
    var rowNum=tb.rows.length;
    for (i=0;i<rowNum;i++)
    {
        tb.deleteRow(i);
        rowNum=rowNum-1;
        i=i-1;
    } 
if( typeSource.length!=0 ){
 $.ajax({
 type: 'POST',
 url: "${ctxFront}/media/PCfront/searchSource",
 dataType: "json",
 cache:true,
 async:false,
 data: {sourceName: keyWord,typeSource:typeSource},
　　    success: function (data) {
  if(data.result == 'success'){

                          //listSource为后台传过来的数组
    var source=data.listSource;
 for(i in source){
  var tbBody = "";
  tbBody += "<tr id=\"template\"><td id=\"name\">"+source[i].name+"</td></tr>";
            $("#datas").append(tbBody); 
 }
}else{
  var tbBody = "";
  tbBody += "<tr id=\"template\"><td id=\"name\">没有您想要的素材</td></tr>";
            $("#datas").append(tbBody); 
} 
     }
});  
}

}
