bootstrap jquery dataTable 异步ajax刷新表格数据

异步请求

            var postData = {
                "env_name" : new_env_name,
                "env_url": new_env_url,
                "env_desc" : new_env_desc
            };
            $.ajax({
                type: 'POST',
                url : '/test_env_add/',
                data : postData,
                dataType : 'json',
                success : function(data){
                    $('#table_test_env').dataTable().fnClearTable();    //清空表格
                    $('#table_test_env').dataTable().fnAddData(packagingdatatabledata(data),true);  //刷下表格
                    $("#modal-container-648308").modal("hide");
                },
                error:function(data){
                    alert("新增失败");
                }
            })

数据处理函数packagingdatatabledata，异步请求返回的data.test_env_all必须是一个json格式数据

    function packagingdatatabledata(data){
         var editHtml='<button href="#modal-container-648308" data-toggle="modal" class="btn btn-xs btn-info" onclick="test_env_modify(this)"> <i class="icon-edit bigger-120"></i> </button> <button href="#modal-container-648300" data-toggle="modal" class="btn btn-xs btn-danger" onclick="test_env_delete(this)"> <i class="icon-trash bigger-120"></i> </button>';
        var a=[];   //全部行数据的list
        var banddata = data.test_env_all;
        for(var key in banddata){
            var tempObj=[];     //一行数据的list
            tempObj.push(banddata[key].id);
            tempObj.push(banddata[key].name);
            tempObj.push(banddata[key].url);
            tempObj.push(banddata[key].desc);
            tempObj.push(editHtml);
            a.push(tempObj);
        }

        return a;
    }
