javascript - 如何控制 Bootstrap Accordion 表单的可见性

Question

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

例如，当我加载页面时，我只希望他们能够看到“1. 选择功能”，当他们打开它并选择他们的元素时，当他们按下一个按钮时，即第二个面板变得可见并打开时.等等。

我假设我可以做一些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代码编写服务，所以如果有人能给我指出正确的方向，我就可以做剩下的事情。

<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。

Answer 1

您可以使用 hide() 方法在 ready 函数中第一次隐藏您想要的 div，例如:

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

之后，您应该为每个按钮 next 添加一个标识符 id，然后为其附加一个 click 事件以控制您的 Accordion 每次点击都如您所愿。

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

希望这对您有所帮助。

$(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>
