Dojo中的DataGrid,来自servlet的json数据

我是第一次使用JSON ……
并希望用我的JSON数据填充我的数据网格,
这是我的JSON数据：

{
  "head": {
    "vars": [ "s","fname","lname" ]
  },"results": {
    "bindings": [
      {
        "s": { "type": "uri","value": "http://tn.gov.in/Person/41" },"fname": { "type": "literal","value": " },"lname": { "type": "literal",n" }
      },{
        "s": { "type": "uri","value": "http://tn.gov.in/Person/37" },"value": "sh" },"value": "Vvan" }
      },"value": "http://tn.gov.in/Person/39" },"value": "Vavan " },"value": "Sran" }
      }
    ]
  }
}

我想在数据网格中显示fname和lname我应该怎么做呢？
任何人都可以提供适用于上述JSON的示例代码吗？我尝试了很多例子,我得到一个空格

这里的关键点是,在dojo网格中使用之前,您需要先转换数据.

现场演示可在here找到.

dojo.require("dojox.grid.DataGrid");
dojo.require("dojo.data.ItemFileReadStore");

dojo.addOnLoad(function() {
    var data = { "head": { "vars": [ "s","lname" ] },"results": { "bindings": [ { "s": { "type": "uri","value": "Gayathri" },"value": "Vasudevan" } },{ "s": { "type": "uri","value": "Magesh" },"value": "Vasudevan " },"value": "Srinivasan" } } ] } };

    var items = dojo.map(data.results.bindings,function(binding) {
        return {fname : binding.fname.value,lname : binding.lname.value};
    });

    var store =  new dojo.data.ItemFileReadStore({
        data : {
          items : items
        }
    });

    _createGrid(store);

    function _createGrid(store) {
        var layout = _getGridLayout(),node = dojo.create("div",{},dojo.byId("grid"),"only");
        var grid = new dojox.grid.DataGrid({
            store : store,structure : layout,rowsPerPage: 10
        },node);
        grid.update();
        grid.startup();
        return grid;
   }

   function _getGridLayout() {
      return [[
          { field : "fname",name : "First Name",width : "50%"},{ field : "lname",name : "Last Name",width : "50%" }
      ]];
   }
});
