dojo小例子（10）改变grid选中行的列值

			<div data-dojo-type="dojo/store/JsonRest" data-dojo-id="myData" data-dojo-props='target: "/rest/user?id="'></div>
			<div data-dojo-type="dojo/data/ObjectStore" data-dojo-id="myStore" data-dojo-props="objectStore: myData"></div>
			<table data-dojo-type="dojox/grid/EnhancedGrid" data-dojo-id="myGrid"
				data-dojo-props='store: myStore, autoWidth:true, autoHeight:true, rowSelector: "20px", 
					plugins:{
						indirectSelection: {headerSelector:true, width:"40px", styles:"text-align: center;"}, 
						pagination: true
					}, 
					loadingMessage : "请稍候...">
				<thead>
				    <tr>
					    <th field="name" width= "200px" >用户名</th>
					    <th field="desc" width= "200px" >描述</th>
				    </tr>
				</thead>
			</table>

				function updateRow( )
				{
					var index = myGrid.selection.selectedIndex;
					var item = myGrid.getItem(index);
					var store = myGrid.store;
					store.setValue(item, 'name', '新名字');
					store.setValue(item, 'desc', '新描述');
				}

改变grid列值实际上是改变store的值，是对store的操作
