過濾Dojo的網格中的數據dojox.grid.DataGrid

Question

我想過濾dojo網格小部件中的數據，但是，我沒有運氣。

下面我發佈了我用來成功創建網格的JavaScript，但是，所有數據都顯示出來了。我試過用引號括住IsBaseLevel並用引號括起來，我似乎無法找到治療方法。與往常一樣，任何幫助或建議表示讚賞。如果您需要更多信息，請告訴我。

使用Javascript（減去dojo.ready到（）函數調用）：

var grid; 

function a() { 
    var store = new dojox.data.JsonRestStore({ target: "/Services/Security/SecurityArea/", idAttribute: "id", syncMode: true }); 
    var gridLayout = [ 
     { name: "Id", field: "Id" }, 
     { name: "Name", field: "Name" }, 
     { name: "Parent Id", field: "Parent", formatter: formatParent }, 
     { name: "Description", field: "Description"}, 
     { name: "IsBaseLevel", field: "IsBaseLevel"}]; 
    grid = new dojox.grid.DataGrid({ 
     store: store, 
     structure: gridLayout 
    }, document.createElement("div")); 

    grid.placeAt(dojo.body(), "last"); 

    grid.startup(); 

    grid.filter({ IsBaseLevel: false }); 
} 

function formatParent(data) { 
    if (typeof data != "undefined" && data != null) { 
     var menu = new dijit.DropDownMenu({ style: "display: none;" }); 
     menu.addChild(new dijit.MenuItem({ 
      label: "Test 1", 
      iconClass: "dijitEditorIcon dijitEditorIconSave", 
      onClick: function() { alert('save'); } 
     })); 
     menu.addChild(new dijit.MenuItem({ 
      label: "Test 1", 
      iconClass: "dijitEditorIcon dijitEditorIconCut", 
      onClick: function() { alert('cut'); } 
     })); 
     var button = new dijit.form.DropDownButton({ 
      label: "hello!", 
      name: "programmatic2", 
      dropDown: menu 
     }); 
     return button; 
    } 
    else return null; 
}

，我發現我的問題。我期望過濾器在客戶端（瀏覽器）收到數據後應用到數據上。但是，在檢查網絡之後，我看到我的服務被調用了一個？IsBaseLevel = false查詢字符串。因此，您的Web服務將需要正確支持您將要應用於您的數據的任何標誌。
