Question

https://fiddle.jshell.net/8v72rtxb/
我有以下代码。

  <div class="menu-horizontal container">
    <div class="row menu-container" id="menu">
      <div class="col-md-3 menu-item">
        <a data-toggle="collapse" class="collapsed collapse-toggle" data-parent="#menu" href="#studies-collapse" aria-expanded="false" aria-controls="collapseExample">
          Studies
        </a>
        <div class="collapse" id="studies-collapse">
          <div class="container">
            <div class="row">
              Something...
            </div>
          </div>
        </div>
      </div>

      <div class="col-md-3 menu-item">
        <a data-toggle="collapse" class="collapsed collapse-toggle" data-parent="#menu" href="#research-collapse" aria-expanded="false" aria-controls="collapseExample">
          Research
        </a>
        <div class="collapse" id="research-collapse">
          <div class="container">
            <div class="row">
              Something...
            </div>
          </div>
        </div>
      </div>

    </div>
  </div>

我不知道为什么data-parent不起作用。展开一个崩溃div不会关闭另一个崩溃。我试图从bootstrap的例子中复制代码，但它仍然无效。同样在我的项目中，我在jquery.js之前添加了bootstrap.min.js。我已经检查了一些其他问题，他们说bootstrap.min.js可能已被包括两次。但那应该是这样吗？
谢谢你的阅读！

Answer 1

我想到了解决方法。即使不使用data-parent属性也是如此。 https://fiddle.jshell.net/zyd1vL4o/

$(document).ready(function(){
    $('.collapse').on('show.bs.collapse', function (e) {
        $('.collapse').collapse("hide")
    })
})

使用：

＆＃13;

<div class="menu-horizontal container">
    <div class="row menu-container" id="menu">
        <div class="col-md-3 menu-item">
            <a data-toggle="collapse" class="collapsed" data-target="#studies-collapse" href="#studies-collapse" aria-expanded="false" aria-controls="studies-collapse">
                Studies
            </a>
            <div class="collapse" id="studies-collapse" data-parent="#menu">
                <div class="container">
                    <div class="row">
                        Something...
                    </div>
                </div>
            </div>
        </div>
        <div class="col-md-3 menu-item">

                        Something...
                    </div>

            </div>
        </div>
    </div>

Answer 4

如果它没有关闭，那么你可能没有正确链接到你的bootstrap js。你不应该添加任何额外的东西。检查以下js文件：

bootstrap.min.js
bootstrap.bundle.min.js

如果你要创建一个bootstrap主题，那么在函数中执行以下操作：
wp_register_script( 'write your theme name here', get_template_directory_uri() . '/bootstrap/js/bootstrap.min.js', array( 'jquery' ) );
