我希望你们能帮我这个忙.

I hope you guys can help me with this one.

当单选按钮 id ="B" 时，如何使单选按钮 id ="A" 将其属性更改为已选中" >被选中?

How can I have a radio button id="A" change it's attribute to 'checked' when radio button id="B" is selected?

单选按钮A和B在不同的组中.

Radio buttons A and B are in different groups.

谢谢！

推荐答案

<input type="radio" name="group1" id="A">Radio A
<input type="radio" name="group2" id="B">Radio B
<input type="radio" name="group2" id="C">Radio C

$("input[type='radio'][name='group2']").change(function() {
  if ($('#B').is(':checked')) {
    $('#A').prop("checked", true);
  } else {
    $('#A').prop("checked", false);
  }
});
