我认为这是一个更好的写法。灵活一点。对不起,我删除了你的一堆东西,以便弄清楚发生了什么。
JS:
$(document).ready(function () {
$(document).on('click', '#radiochk1', function(){
var checkedRadio = $('input[name="question1"]:checked');
$('.correct, .incorrect').removeClass('correct').removeClass('incorrect');
if(checkedRadio.hasClass('rightAnswer')){
checkedRadio.parent().find('span.answer').addClass('correct');
}else{
checkedRadio.parent().find('span.answer').addClass('incorrect');
}
});
$(document).on('click', '#resetq1', function(){
$('.correct, .incorrect').removeClass('correct').removeClass('incorrect');
$('input[name="question1"]').attr('checked', false);
});
});
HTML:
<form class="ra">
<div class="cor">
<input type="radio" name="question1" class="c1" />A. Choice A<span class="hiddencorr">Correct answer</span>
