淘汰赛检查绑定不适用于单选按钮

Question

敲除检查绑定不起作用，遵循以下敲除给出的示例。

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

代码如下。

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

默认选择味精的值。首次加载一次页面。

问候

我想你忘了打电话给ko.applyBindings(viewModel);
