Question

我正在尝试过滤dojo网格小部件中的数据，但是，我没有运气。

下面我发布了用于成功创建网格的javascript，但是，显示了所有数据。我试过封闭IsBaseLevel引号和引号中的false，我似乎无法找到治愈方法。与往常一样，任何帮助或建议都表示赞赏。如果您需要更多信息，请告诉我。

Javascript（减去从dojo.ready到a（）的函数调用）：

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;
}

我发现了我的问题。我希望在客户端（浏览器）收到数据后，将过滤器应用于数据。但是，在检查网络后，我看到我的服务是用？IsBaseLevel = false查询字符串调用的。因此，您的Web服务需要正确支持您将应用于数据的任何标志。

在Dojo的Grid dojox.grid.DataGrid中过滤数据
