请问DataGrid在前台加载JSON串是怎么的形式

hehehaha

js code:
var gridData = '{ "total": 1, "data": [ {  "tradydate": "2013-04-23"  } ] }';


html code:
<div id="datagrid1" class="mini-datagrid" idField="id" data="gridData">

</div>
这样写为什么不行呢？
请问我应该如何处理

factory

var gridData  = [ {  "tradydate": "2013-04-23"  } ]

grid.setData(gridData )

hehehaha
