Question

广东话＆＃39;使这个jquery正常工作：

$(".btn-0").click(function(){
    $('.btn-0').addClass('btn-success');
    $('.btn-1,.btn-2, .btn-3, .btn-4, .btn-7, .btn-10, .btn-13, .btn-16, .btn-19, .btn-22, .btn-25, .btn-28, .btn-31, .btn-34, .btn-37, .btn-40, .btn-43, .btn-46, .btn-49, .btn-52').removeClass('btn-success');
});

if ($('.btn-0').hasClass('btn-success')) {
    $('.option-1').addClass('green'); 
}
else {
    $('.option-1').removeClass('green');
}

这个想法是：如果btn-0有类btn-success，div选项-1接收类green ... 如果btn-1 / btn-2 / btn-3具有类btn-success，则div选项-2接收类绿色... 等。

HTML是：

 <div class="option-1 row">
    <div class="col-md-1"><span class=" badge-0">#</span></div>
    <div class="atividade col-md-8"><p>Painel – O cenário econômico brasileiro <span class="red">(60 minutos)</span></p>Bradesco
    </div>
    <div class="col-md-3"><a id="test" class="btn-0 btn btn-small btn-danger">9h30</a>
    </div>
  </div>
  <div class="option-2 row" >

Answer 1

试试这个：

$(".btn-0").click(function(){
    $('.btn-0').addClass('btn-success');
    $('.btn-1,.btn-2, .btn-3, .btn-4, .btn-7, .btn-10, .btn-13, .btn-16, .btn-19, .btn-22, .btn-25, .btn-28, .btn-31, .btn-34, .btn-37, .btn-40, .btn-43, .btn-46, .btn-49, .btn-52').removeClass('btn-success');

if ($('.btn-0').hasClass('btn-success')) {
    $('.option-1').addClass('green'); 
}
else {
    $('.option-1').removeClass('green');
}
});

Answer 2

我认为这是你想要的，但不是100％肯定

$(".btn").click(function(){
    var row = $(this).closest('.row');
    if( row.hasClass('btn-success') ) {
        row.removeClass('btn-success green');
    } else {
        row.addClass('btn-success green');
    }
});
