我有一个datagrid全部设置,连接到一个XMLStore。当用户从下拉列表中选择一个月时,我希望网格只过滤那个月的数据。应该是简单的,根据每个例子。我无法弄清楚它为什么不起作用,也不知道为什么IE告诉我dataGrid对象不支持任何方法(filter,sort,setQuery)。过滤一个Dojo DataGrid

作为除此之外,而点击事件完美的作品,当我尝试应用在这个页面的加载,当电网第一次加载它过滤电网的过滤器。

我试图添加一个过滤器,将它添加到上面创建的现有addOnLoad函数中,我甚至尝试将我的下拉列表的值替换为加载时我的网格的起始查询。

你可以让你的网格从全球范围访问通过设置jsId属性(jsId =“eventGrid”),也可以通过ID找到它:

dijit.byId("eventGrid").filter({month:rtrn}); 
0

我想你想的id =“eventGrid”读jsId =“eventGrid”或添加其他属性为jsId =“eventGrid”

+0
