求datagrid,怎么搞都没数据

xoao

<div id="datagrid1" class="mini-datagrid" style="width:100%;height:100%;"
     url="/api/Values/"
     @*url="/Home/Demo"*@
     idfield="name"
     sizelist="[5,10,20,50]" pagesize="10">
    <div property="columns">
        <div type="checkcolumn"></div>
        <div field="loginname" width="120" headeralign="center" allowsort="true">员工帐号</div>
        <div field="name" width="120" headeralign="center" allowsort="true">姓名</div>
    </div>
</div>

mini.parse();
var grid = mini.get("datagrid1");
grid.load();


url返回的数据：
{"avgAge":0,"total":100,"maxAge":0,"minAge":0,"data":[{"loginname":"loginname>0","name":"name>0"},{"loginname":"loginname>1","name":"name>1"},{"loginname":"loginname>2","name":"name>2"}]}

看数据结构没什么问题
