大约一个月前,米特的问题无人回答.可悲的是,我现在也遇到了同样的情况.
About a month ago Mitt’s question went unanswered. Sadly, I’m running into the same situation now.

情况如下:我正在使用 jQuery 来捕获单选按钮中的更改.当单选按钮被选中时,我启用了一个编辑框.当取消选择单选按钮时,我希望禁用编辑框.
Here’s the situation: I’m using jQuery to capture the changes in a radio button. When the radio button is selected I enable an edit box. When the radio button is de-selected, I would like the edit box to be disabled.
启用工作.当我在组中选择不同的单选按钮时,change
事件not 被触发.有谁知道如何解决这个问题?
The enabling works. When I choose a different radio button in the group, the change
event is not fired. Does anyone know how to fix this?
<input type="radio" id="r1" name="someRadioGroup"/>
<script type="text/javascript">
$("#r1").change(function () {
if ($("#r1").attr("checked")) {
$('#r1edit:input').removeAttr('disabled');
}
else {
$('#r1edit:input').attr('disabled', true);
}
});
</script>
看起来 change()
函数仅在您选中一个单选按钮时调用,而不是在您取消选中它时调用.我使用的解决方案是将更改事件绑定到每个单选按钮:
Looks like the change()
function is only called when you check a radio button, not when you uncheck it. The solution I used is to bind the change event to every radio button:
$("#r1, #r2, #r3").change(function () {
或者您可以为所有单选按钮指定相同的名称:
Or you could give all the radio buttons the same name:
$("input[name=someRadioGroup]:radio").change(function () {
这是一个有效的 jsfiddle 示例(更新自 Chris Porter 的评论.)
Here's a working jsfiddle example (updated from Chris Porter's comment.)
根据@Ray 的评论,您应该避免使用带有 .
的名称.这些名称在 jQuery 1.7.2 中有效,但在其他版本中无效(jsfiddle 示例.).
Per @Ray's comment, you should avoid using names with .
in them. Those names work in jQuery 1.7.2 but not in other versions (jsfiddle example.).
