javascript - 使用 Bootstrap 下拉菜单显示/隐藏容器？

Question

我有下拉菜单，应显示用户从下拉菜单中选择的部分。我创建了一个简单的示例来展示我的代码以及如何显示/隐藏容器。到目前为止一切正常。

$(document).ready(function() {
  $('#main-menu').find('a[data-container=hearing-container]').trigger('click').parent().addClass('active');
  $('#main-container > div[id=test-container]').show();
  $('#main-container > div:not([id=test-container])').hide();

});

$("#main-menu li a").on('click', mainMenu);

function mainMenu() {
  var itemID = $(this).attr('data-container');
  $(this).parent().addClass('active').siblings().removeClass('active');
  $('#main-container > div[id="' + $(this).attr('data-container') + '"]').show();
  $('#main-container > div:not([id="' + $(this).attr('data-container') + '"])').hide();
}

<div id="main-container" class="container">
  <nav class="navbar navbar-default">
    <div class="container-fluid">
      <p class="navbar-text"><span class="glyphicon glyphicon-home"></span> <b>Welcome to Single Page Application!</b></p>
      <ul class="nav navbar-nav navbar-right">
        <li class="dropdown">
          <a class="dropdown-toggle" data-toggle="dropdown" href="#">Menu<span class="caret"></span></a>
          <ul id="main-menu" class="dropdown-menu">
            <li><a href="#" data-container="home-container">Home</a></li>
            <li><a href="#" data-container="test-container">Test</a></li>
            <li><a href="#" data-container="reports-container">Reports</a></li>
            <li><a href="#" data-container="settings-container">Settings</a></li>
          </ul>
        </li>
      </ul>
    </div>
  </nav>
  <div id="home-container">
    <ul id="agecny-navbar" class="nav nav-tabs">
      <li class="active"><a data-toggle="tab" href="#agency-myaccount">My Account</a></li>
      <li><a data-toggle="tab" href="#agency-finduser">Find User</a></li>
    </ul>
    <div class="tab-content">
      <div id="agency-myaccount" class="tab-pane fade in active" data-name="MyAccount">
        <form name="frm_myaccount" id="frm_myaccount" class="frm-agencySubmit" autocomplete="off">
          <div class="form-group required">
            <label class="control-label" for="acctive">Account Active</label>
            <select class="form-control" name="frm_active" id="frm_active" required>
                                        <option value="">-- Select the option --</option>
                                        <option value="0">No</option>
                                        <option value="1">Yes</option>
                                    </select>
          </div>
      </div>
    </div>
  </div>
</div>
<div id="test-container">
  Test
</div>
<div id="reports-container">
  Reports
</div>
<div id="settings-container">
  Settings
</div>
</div>

然后我添加了更多在我的容器中实际使用的代码。在这种情况下，上一个示例中的代码会中断并显示所有容器。我已经一步一步地走了，似乎一旦我添加带有元素的 form 标签，代码就开始中断。如果我删除一切正常。我不确定 Bootstrap 是否不支持这些方法或其他原因导致了此问题。如果有人发现我的代码中的问题出在哪里，请告诉我。谢谢。

您错过了“Form”结束，并在 div (“#home-container”) 后添加了一个额外的“Div”结束。

更新以下代码:
