jquery - 显示折叠面板并编辑其他面板类

Question

我想显示带有按钮的折叠面板，然后编辑其他面板的类，使其适合页面宽度。这是我的代码

按钮

// first try
$('#signup').on('click', function() {
  $('#table').removeClass('col-md-12').addClass('col-md-8');
});
// second try
$('#signup').on('click', function() {
  $('#table').toggleClass('col-md-12 col-md-8');
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button class="btn btn-success" data-toggle="collapse" data-target="#panel" id="signup">Signup</button>

<div class="form-row">
  <!-- panel 1 -->
  <div class="form-group col-md-4 collapse" id="panel">
    // stuff here
  </div>

  <!-- panel 2 -->
  <div class="form-group col-md-12 ml-auto" id="table">
    // stuff here
  </div>
</div>

当我点击按钮时，我希望面板 1 出现，然后面板 2 类 col-md-12 更改为 col-md-8，因此它可以适应引导网格系统。我尝试了 onclick 触发器，但它不起作用。

$('#panel').on('hidden.bs.collapse', function(e) {
  $('#table').toggleClass('col-xs-12').toggleClass('col-xs-8');
}).on('show.bs.collapse', function(e) {
  $('#table').toggleClass('col-xs-8').toggleClass('col-xs-12');
})

.form-row.row {
  margin-right: 0px;
  margin-left: 0px;
}

不使用 Bootstrap 网格系统的更新代码段。

$('#panel').on('hidden.bs.collapse', function(e) {
  $('#table').toggleClass('col-xs-12');
}).on('show.bs.collapse', function(e) {
  $('#table').toggleClass('col-xs-12');
})

.some-sontainer {
  margin-right: 0px;
  margin-left: 0px;
  display: flex;
}

.some-sontainer .col1{
  width: 200px;
}

.some-sontainer .col2{
  width: 100%;
}

#table{
  background-color: red;
}

#panel{
  background-color: green;
}
