Question

当我使用Bootstrap下拉列表和nanoscrollerJS插件时，会发生一些非常烦人的事情。下拉菜单时不会触发nanoscroller插件。它会在您使用firebug后立即触发并再次查看下拉列表。看起来下拉列表隐藏在DOM中，即使它已被触发。如何正确触发纳米尺度？

我创造了一个小提琴来演示这个问题： https://jsfiddle.net/spw1khad/

代码：

    <div class="dropdown">
  <button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown" aria-haspopup="true" aria-expanded="true">
    Dropdown
    <span class="caret"></span>
  </button>

  <ul class="dropdown-menu" aria-labelledby="dropdownMenu1">
          <div id="about" class="nano">
        <div class="nano-content">
    <li><a href="#">Action</a></li>
    <li><a href="#">Another action</a></li>
    <li><a href="#">Something else here</a></li>
    <li><a href="#">Separated link</a></li>
      <li><a href="#">Action</a></li>
    <li><a href="#">Another action</a></li>
    <li><a href="#">Something else here</a></li>
    <li><a href="#">Separated link</a></li>
      <li><a href="#">Action</a></li>
    <li><a href="#">Another action</a></li>
    <li><a href="#">Something else here</a></li>
    <li><a href="#">Separated link</a></li>
            <li><a href="#">Action</a></li>
    <li><a href="#">Another action</a></li>
    <li><a href="#">Something else here</a></li>
    <li><a href="#">Separated link</a></li>
      <li><a href="#">Action</a></li>
    <li><a href="#">Another action</a></li>
    <li><a href="#">Something else here</a></li>
    <li><a href="#">Separated link</a></li>
      <li><a href="#">Action</a></li>
    <li><a href="#">Another action</a></li>
    <li><a href="#">Something else here</a></li>
    <li><a href="#">Separated link</a></li>
            <li><a href="#">Action</a></li>
    <li><a href="#">Another action</a></li>
    <li><a href="#">Something else here</a></li>
    <li><a href="#">Separated link</a></li>
      <li><a href="#">Action</a></li>
    <li><a href="#">Another action</a></li>
    <li><a href="#">Something else here</a></li>
    <li><a href="#">Separated link</a></li>
      <li><a href="#">Action</a></li>
    <li><a href="#">Another action</a></li>
    <li><a href="#">Something else here</a></li>
    <li><a href="#">Separated link</a></li>
            <li><a href="#">Action</a></li>
    <li><a href="#">Another action</a></li>
    <li><a href="#">Something else here</a></li>
    <li><a href="#">Separated link</a></li>
      <li><a href="#">Action</a></li>
    <li><a href="#">Another action</a></li>
    <li><a href="#">Something else here</a></li>
    <li><a href="#">Separated link</a></li>
      <li><a href="#">Action</a></li>
    <li><a href="#">Another action</a></li>
    <li><a href="#">Something else here</a></li>
    <li><a href="#">Separated link</a></li>
  </div>
    </div>  
            </ul>

</div>

Answer 1

首先是一个小标记评论;您在<div>代码后直接使用<ul>代码，这是不正确的。我在下面的代码中改进了这部分。另请参阅Can I use div as a direct child of UL?

现在你的问题，似乎bootstrap触发了一些js功能，当你点击下拉按钮导致＆＃39;崩溃＆＃39; nanoscroller。使用带有超时的点击事件有点苛刻，但它可以帮到你。

html部分

<button class="btn btn-default dropdown-toggle" type="button" id="dropdownMenu1" data-toggle="dropdown" aria-haspopup="true" aria-expanded="true">Dropdown <span class="caret"></span>

</button>
<div class="dropdown-menu" aria-labelledby="dropdownMenu1">

                <li><a href="#">Separated link</a>
                </li>
            </ul>
        </div>
    </div>
</div>

和js部分：

$('#dropdownMenu1').click(function () {
    setTimeout(function () {
        $(".nano").nanoScroller();
    }, 100);
});
