推荐答案

网站错误轨道：

onchange事件可以附加（内联或作为事件处理程序）到任何表单元素。每当表单字段的值更改时触发。不幸的是，IE的行为是有点奇怪，因为对于复选框或单选按钮字段，事件不会触发时，它应该（当你单击要选择的选项时），而是它只有当你点击页面/窗体上的其他地方，或者如果你明确调用blur（）;

The onchange event can be attached (inline or as an event handler) to any form element. It fires whenever the value of the form field changes. Unfortunately, the behavior is a bit strange in IE, in that for a checkbox, or a radio button field, the event doesn't fire when it is supposed to (right when you click the option you want to choose), but instead it only fires, when you click elsewhere on the page/form, or if you explicitly call blur(); on the field.

建议的解决方法是：

<input type="radio" name="foo" value="Green" onclick="alert(this.value);"/>Green
<input type="radio" name="foo" value="Blue" onclick="alert(this.value);"/>Blue
