如何控制 Bootstrap Accordion 表单的可见性

Question

我使用 bootstrap 手风琴作为创建表单的独特方式。基本上，该表格在其自己的手风琴面板中有 7 个部分。现在我有它，就像我想要的那样，它们都被折叠了，当你打开第一个手风琴时，有一个链接到第二个手风琴的按钮。这正是我希望它工作的方式。但是，在选择“下一步”按钮之前，有没有办法隐藏其他手风琴面板？

例如，当我加载页面时，我只希望他们能够看到“1. Select Features”，当他们打开该页面并在他们按下下一个按钮时选择他们的项目时，即第二个面板变得可见并打开.等等。

我假设我可以做一些我隐藏它们并且按钮触发它可见的事情？我一直在寻找这样的例子，但我找不到任何东西。我知道这个网站不是一个代码编写服务，所以如果有人能指出我正确的方向，我可以做剩下的事情。

<div class="panel-group" id="accordion">
  <div class="panel panel-default" id="panel1">
    <div class="panel-heading">
      <h4 class="panel-title"> <a data-toggle="collapse" data-parent="#accordion" href="#collapseOne"> 1. Select Features </a> </h4>
    </div>
    <div id="collapseOne" class="panel-collapse collapse">
      <div class="panel-body">
            Testing 1
        <button type="button" class="btn btn-success" data-toggle="collapse" data-parent="#accordion" href="#collapseTwo"> Next </button>
      </div>
    </div>
  </div>


  <div class="panel panel-default" id="panel2">
    <div class="panel-heading">
      <h4 class="panel-title"> <a data-toggle="collapse" data-parent="#accordion" href="#collapseTwo"> 2. Select Styles </a> </h4>
    </div>
    <div id="collapseTwo" class="panel-collapse collapse">
      <div class="panel-body">
          Testing 2
        <button type="button" class="btn btn-success" data-toggle="collapse" data-parent="#accordion" href="#collapseThree"> Next </button>
      </div>
    </div>
  </div>


  <div class="panel panel-default" id="panel3">
    <div class="panel-heading">
      <h4 class="panel-title"> <a data-toggle="collapse" data-parent="#accordion" href="#collapseThree"> 3. Contact Info </a> </h4>
    </div>
    <div id="collapseThree" class="panel-collapse collapse">
      <div class="panel-body">
          Testing 3
        <button type="button" class="btn btn-success" data-toggle="collapse" data-parent="#accordion" href="#collapseFour"> Next </button>
      </div>
    </div>
  </div>

</div>

我在 JSFiddle 中重新创建了它，因此您可以看到我在说什么并使用它。

您可以使用hide() 方法在准备功能上第一次隐藏您想要的div，例如：

$('#panel2, #panel3').hide();

之后，您应该将标识符 id 添加到每个按钮 next，然后将 click 事件附加到它以控制您的 accordion，就像您希望每次点击一样。

$('body').on('click', '#btn-next-id', function(){
    //Here show hide divs you want
})

希望这会有所帮助。

$(function(){
    //Hide other steps for the first time
    $('#panel2, #panel3').hide();
    
    $('body').on('click', '#next1', function(){
        $('#panel2').show();
    })

    $('body').on('click', '#next2', function(){
        $('#panel3').show();
    })
})

I'm using the bootstrap accordion. 


<div class="panel-group" id="accordion">
  <div class="panel panel-default" id="panel1">
    <div class="panel-heading">
      <h4 class="panel-title"> <a data-toggle="collapse" data-parent="#accordion" href="#collapseOne"> 1. CHOOSE YOUR INDUSTRY </a> </h4>
    </div>
    <div id="collapseOne" class="panel-collapse collapse">
      <div class="panel-body">
            Testing 1
        <button id="next1" type="button" class="btn btn-success" data-toggle="collapse" data-parent="#accordion" href="#collapseTwo"> Next </button>
      </div>
    </div>
  </div>


  <div class="panel panel-default" id="panel2">
    <div class="panel-heading">
      <h4 class="panel-title"> <a data-toggle="collapse" data-parent="#accordion" href="#collapseTwo"> 2. STANDARD FEATURES </a> </h4>
    </div>
    <div id="collapseTwo" class="panel-collapse collapse">
      <div class="panel-body">
          Testing 2
        <button id="next2" type="button" class="btn btn-success" data-toggle="collapse" data-parent="#accordion" href="#collapseThree"> Next </button>
      </div>
    </div>
  </div>


  <div class="panel panel-default" id="panel3">
    <div class="panel-heading">
      <h4 class="panel-title"> <a data-toggle="collapse" data-parent="#accordion" href="#collapseThree"> 3. REAL ESTATE FEATURES </a> </h4>
    </div>
    <div id="collapseThree" class="panel-collapse collapse">
      <div class="panel-body">
          Testing 3
        <button id="next3" type="button" class="btn btn-success" data-toggle="collapse" data-parent="#accordion" href="#collapseFour"> Next </button>
      </div>
    </div>
  </div>

我不确定这是否正是您要查找的内容，但是如何简单地从第 2 步和第 3 步的标题中删除锚元素，以便用户无法单击它们来打开它们？在这里更新小提琴：https://jsfiddle.net/DTcHh/15338/

您甚至在第 2 步和第 3 步中添加了一个“上一步”按钮，以便他们可以返回该过程？在这里更新小提琴：https://jsfiddle.net/DTcHh/15339/
