这是示例http://jsfiddle.net/HhXGH/57/
我正在单击 jquery 的单选按钮,但 knockout.js 无法识别它。它仍然显示第一次单击的值。
<p>Send me spam: <input type="checkbox" data-bind="checked: wantsSpam" /></p>
<div data-bind="visible: wantsSpam">
Preferred flavor of spam:
<div><input type="radio" name="flavorGroup" value="cherry" data-bind="checked: spamFlavor" /> Cherry</div>
<div><input type="radio" name="flavorGroup" value="almond" data-bind="checked: spamFlavor" /> Almond</div>
<div><input type="radio" name="flavorGroup" value="msg" data-bind="checked: spamFlavor" /> Monosodium Glutamate</div>
</div>
var viewModel = {
wantsSpam: ko.observable(true),
spamFlavor: ko.observable('cherry')
};
ko.applyBindings(viewModel);
$(':radio:last').click();
alert(viewModel.spamFlavor())
