knockout.js - 剔除检查绑定不适用于单选按钮

Question

剔除检查绑定不起作用，遵循以下由剔除给出的示例。

http://knockoutjs.com/documentation/checked-binding.html

代码可以在下面看到。

http://jsfiddle.net/c2TSm/

var viewModel = {
    wantsSpam: ko.observable(true),
    spamFlavor: ko.observable("almond") // Initially selects only the Almond radio button
};

// ... then later ...
viewModel.spamFlavor("msg"); // Now only Monosodium Glutamate is checked

应默认选择味精的值。一次页面加载第一次。

问候

我想你忘了打电话ko.applyBindings(viewModel);
