javascript - dxSelectBox将不会加载数据

根据DevExtreme网站上的演示，我有一个dxSelectBox，但无法加载数据。代码如下：

<div data-bind="dxSelectBox:{datasource: themes, displayExpr: 'name', valueExpr: 'themeId', value: themeId }"></div>

var themesArray = [
    { themeId: 1, name: "Android (Dunkel)" },
    { themeId: 2, name: "Desktop" },
    { themeId: 3, name: "iOS" },
    { themeId: 4, name: "Windows 8" },
    { themeId: 5, name: "Windows Phone 8" },
    { themeId: 6, name: "Tizen" },
    ];

var themes = new DevExpress.data.DataSource(themesArray);

var viewModel = {
    themes: themes,
    viewShowing: function () {
        this.themes.load();
        },
}

有人可以指出正确的方向吗？

提前致谢

最佳答案

叹...

<div data-bind="dxSelectBox:{datasource

应该用大S读dataSource
