我有一个功能，检查“收音机已检查并更改颜色”

function checkChanges()
{

    $('.radiobutton font').attr('color', 'red');

    $('.radiobutton :checked').closest('.radiobutton').find('font').attr('color', 'green');
}

$(function()
  {
  checkChanges();
  $('.radiobutton :radio').on('click', checkChanges);
  });

我想在该代码中添加一个函数，取消选中Radio，如果已选中并再次单击（onClick），这也应该将颜色更改为红色。

Answer 1

几乎没有更正......

删除:checked之前的空格。变化：

$('.radiobutton :checked').closest('.radiobutton').find('font').attr('color', 'green');

要：

$('.radiobutton:checked').closest('.radiobutton').find('font').attr('color', 'green');

您需要在此处使用input[type="radio"]。变化：

$('.radiobutton :radio').on('click', checkChanges);

要：

$('input.radiobutton[type="radio"]').on('click', checkChanges);

jQuery检查道具。无线电和取消选中onClick
