Question

我正在尝试将两个单选按钮与kendo MVVM绑定。但是，它始终默认不选中任何单选按钮。这是剑道MVVM中的错误吗？我期待第一次看到页面时检查其中一个单选按钮。

使用attr绑定。

<input type="radio" data-bind="attr: { value: Permission.Read }, checked: checkedValue" name="RadioGroup0"/>
<input type="radio" data-bind="attr: { value: Permission.Modify }, checked: checkedValue" name="RadioGroup0"/>
