我有13个科目，例如:物理学，数学，生物学..... 学生可以选择任意数量的科目，每个科目都有两个单选按钮，一个是A，另一个是As，

那么我如何获取已检查的单选按钮的值? 使用jQuery

推荐答案

这将循环遍历文档中所有已检查的单选元素:

This would loop through all the radio elements in the document that have been checked:

$('input:radio:checked').each(function() {
    var value = $(this).val();
    // do something with radio or value
});

如果要获取特定无线电组的检查值，请执行以下操作:

If you wanted to get the checked value of a particular radio group, you would do:

var value = $('input:radio[name=myradios]:checked').val();

因此，如果您的HTML是这样的:

So if your HTML was like this:

<input type='radio' name='myradios' value='1'>
<input type='radio' name='myradios' value='2' checked='checked'>
<input type='radio' name='myradios' value='3'>

value为2
