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" } ,
        "fname": { "type": "literal" , "value": "sh" } ,
        "lname": { "type": "literal" , "value": "Vvan" }
      } ,
      {
        "s": { "type": "uri" , "value": "http://tn.gov.in/Person/39" } ,
        "fname": { "type": "literal" , "value": "Vavan " } ,
        "lname": { "type": "literal" , "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" , "fname" , "lname" ] } , "results": { "bindings": [ { "s": { "type": "uri" , "value": "http://tn.gov.in/Person/41" } , "fname": { "type": "literal" , "value": "Gayathri" } , "lname": { "type": "literal" , "value": "Vasudevan" } } , { "s": { "type": "uri" , "value": "http://tn.gov.in/Person/37" } , "fname": { "type": "literal" , "value": "Magesh" } , "lname": { "type": "literal" , "value": "Vasudevan" } } , { "s": { "type": "uri" , "value": "http://tn.gov.in/Person/39" } , "fname": { "type": "literal" , "value": "Vasudevan " } , "lname": { "type": "literal" , "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%" }
      ]];
   }
});
