本文介绍了Rails 3 中的 twitter bootstrap 下拉菜单的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我无法使用 twitter bootstrap 在导航栏中使用下拉菜单，我有:

<div class="navbar-inner"><div class="container-fluid"><a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse"><span class="icon-bar"></span><span class="icon-bar"></span><span class="icon-bar"></span></a><div class="nav-collapse collapse"><ul class="nav"><a href="#" class="dropdown-toggle" data-toggle="dropdown">下拉菜单 <b class="caret"></b></a><ul class="下拉菜单"><li><a href="#">动作</a></li><li><a href="#">另一个动作</a></li><li><a href="#">这里还有别的东西</a></li><li class="divider"></li><li><a href="#">分隔链接</a></li>
</div><!--/.nav-collapse --></div><!--/.container-fluid --></div><!--/.navbar-inner --></div><!--/.navbar -->

并且包含在头部的 javascript 如下:

<html lang="zh-cn"><头><meta charset="utf-8"><link href="/assets/application.css?body=1" media="all" rel="stylesheet" type="text/css"/><link href="/assets/custom.css?body=1" media="all" rel="stylesheet" type="text/css"/><script src="/assets/jquery.js?body=1" type="text/javascript"></script><script src="/assets/jquery_ujs.js?body=1" type="text/javascript"></script><script src="/assets/bootstrap-transition.js?body=1" type="text/javascript"></script><script src="/assets/bootstrap-affix.js?body=1" type="text/javascript"></script><script src="/assets/bootstrap-alert.js?body=1" type="text/javascript"></script><script src="/assets/bootstrap-button.js?body=1" type="text/javascript"></script><script src="/assets/bootstrap-carousel.js?body=1" type="text/javascript"></script><script src="/assets/bootstrap-collapse.js?body=1" type="text/javascript"></script><script src="/assets/bootstrap-dropdown.js?body=1" type="text/javascript"></script><script src="/assets/bootstrap-modal.js?body=1" type="text/javascript"></script><script src="/assets/bootstrap-scrollspy.js?body=1" type="text/javascript"></script><script src="/assets/bootstrap-tab.js?body=1" type="text/javascript"></script><script src="/assets/bootstrap-tooltip.js?body=1" type="text/javascript"></script><script src="/assets/bootstrap-popover.js?body=1" type="text/javascript"></script><script src="/assets/bootstrap-typeahead.js?body=1" type="text/javascript"></script><script src="/assets/bootstrap.js?body=1" type="text/javascript"></script><script src="/assets/application.js?body=1" type="text/javascript"></script>...

所以 jquery 被包含在 bootstrap.js 之前，我缺少什么?我做错了什么?

我已经清理了我的 application.js，所以现在头部看起来像这样:

<html lang="zh-cn"><头><meta charset="utf-8"><link href="/assets/application.css?body=1" media="all" rel="stylesheet" type="text/css"/><link href="/assets/custom.css?body=1" media="all" rel="stylesheet" type="text/css"/><script src="/assets/application.js?body=1" type="text/javascript"></script>...

现在出现一个向上的白色三角形，以前没有出现过，但没有出现整个下拉菜单...

解决方案

问题出在我在布局中使用的一些 twitter bootstrap modals，如下所示:

我改为:

现在一切正常，我希望这对其他人有帮助

I can't get a dropdown working, inside navbar using twitter bootstrap, I have:

<div class="navbar navbar-inverse navbar-fixed-top">
  <div class="navbar-inner">
    <div class="container-fluid">
      <a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </a>     
      <div class="nav-collapse collapse">
        <ul class="nav">
          <li class="dropdown">
            <a href="#" class="dropdown-toggle" data-toggle="dropdown">
              Dropdown <b class="caret"></b></a>
            <ul class="dropdown-menu">
              <li><a href="#">Action</a></li>
              <li><a href="#">Another action</a></li>
              <li><a href="#">Something else here</a></li>
              <li class="divider"></li>
              <li><a href="#">Separated link</a></li>
            </ul>
          </li>
        </ul>
      </div><!--/.nav-collapse -->
    </div><!--/.container-fluid -->
  </div><!--/.navbar-inner -->
</div><!--/.navbar -->

and the javascript in included in the head has follows:

<!DOCTYPE html>
<html lang="en">
  <head>
  <meta charset="utf-8">
    <link href="/assets/application.css?body=1" media="all" rel="stylesheet" type="text/css" />
    <link href="/assets/custom.css?body=1" media="all" rel="stylesheet" type="text/css" />
<script src="/assets/jquery.js?body=1" type="text/javascript"></script>
    <script src="/assets/jquery_ujs.js?body=1" type="text/javascript"></script>
    <script src="/assets/bootstrap-transition.js?body=1" type="text/javascript"></script>
    <script src="/assets/bootstrap-affix.js?body=1" type="text/javascript"></script>
    <script src="/assets/bootstrap-alert.js?body=1" type="text/javascript"></script> 
    <script src="/assets/bootstrap-button.js?body=1" type="text/javascript"></script>
    <script src="/assets/bootstrap-carousel.js?body=1" type="text/javascript"></script>
    <script src="/assets/bootstrap-collapse.js?body=1" type="text/javascript"></script>
    <script src="/assets/bootstrap-dropdown.js?body=1" type="text/javascript"></script>
    <script src="/assets/bootstrap-modal.js?body=1" type="text/javascript"></script>
    <script src="/assets/bootstrap-scrollspy.js?body=1" type="text/javascript"></script>
    <script src="/assets/bootstrap-tab.js?body=1" type="text/javascript"></script>
    <script src="/assets/bootstrap-tooltip.js?body=1" type="text/javascript"></script>
    <script src="/assets/bootstrap-popover.js?body=1" type="text/javascript"></script>
    <script src="/assets/bootstrap-typeahead.js?body=1" type="text/javascript"></script>
    <script src="/assets/bootstrap.js?body=1" type="text/javascript"></script>
    <script src="/assets/application.js?body=1" type="text/javascript"></script>
    ...

So jquery is being included before bootstrap.js, what I'm missing ? what I'm doing wrong ?



Edit:
I've cleaned my application.js so now the head looks like this:
<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <link href="/assets/application.css?body=1" media="all" rel="stylesheet" type="text/css" />
    <link href="/assets/custom.css?body=1" media="all" rel="stylesheet" type="text/css" />
    <script src="/assets/application.js?body=1" type="text/javascript"></script>
...
And now appears a white triangle pointing up, that wasn't appearing before, but doesn't appear the whole dropdown...

 解决方案 
The problem turns out to be some twitter bootstrap modals that I was using in my layouts like this:
<div class="modal fade" id="modal_terms">
Instead of that I've changed to:
<div class="modal hide" id="modal_terms">
And it's all working properly now, I hope this helps someone else
