UI Bootstrap下拉指令导致multidir问题

Question

嗨,我正在尝试从UI Bootstrap中获取下拉指令.每当我尝试使用'dropdown'指令时,我都会收到以下错误消息:

控制台错误消息:

Multiple directives [dropdown, dropdown] asking for 'dropdown' controller on: <li class="dropdown pos-stc" dropdown="">
http://errors.angularjs.org/1.3.9/$compile/multidir?p0=dropdown&p1=dropdown&p2='dropdown'ontroller&p3=%3Cli%class%3D%dropdown%20pos-stc%22%20dropdown%3D%22%22%3E

有人能告诉我这个错误是什么吗？当我删除指令一切都很好,除了下拉菜单不起作用:(

HTML:

  <li class="dropdown" dropdown>
    <a href class="dropdown-toggle clear" dropdown-toggle>
      <span class="thumb-sm avatar pull-right m-t-n-sm m-b-n-sm m-l-sm">
        <img src="img/a0.jpg" alt="...">
        <i class="on md b-white bottom"></i>
      </span>
      <span class="hidden-sm hidden-md">John.Smith</span> <b class="caret"></b>
    </a>
    <!-- dropdown -->
    <ul class="dropdown-menu animated fadeInRight w">
      <li class="wrapper b-b m-b-sm bg-light m-t-n-xs">
        <div>
          <p>300mb of 500mb used</p>
        </div>
        <progressbar value="60" class="progress-xs m-b-none bg-white"></progressbar>
      </li>
      <li>
        <a href>
          <span class="badge bg-danger pull-right">30%</span>
          <span>Settings</span>
        </a>
      </li>
      <li>
        <a ui-sref="app.page.profile">Profile</a>
      </li>
      <li>
        <a ui-sref="app.docs">
          <span class="label bg-info pull-right">new</span>
          Help
        </a>
      </li>
      <li class="divider"></li>
      <li>
        <a ui-sref="access.signin">Logout</a>
      </li>
    </ul>
    <!-- / dropdown -->
  </li>

Answer 1

假设您没有使用最新版本的bootstrap.以前的版本(例如:0.11.0)C除了属性restricted(A)之外还有指令类restricted().因此,您通过指定类以及属性来重复元素的指令.这会导致多个指令错误.你可以使用classname,因为无论如何你都需要它来适用于适当的内置bootstrap css规则.如换<li class="dropdown" dropdown>到<li class="dropdown">或者其升级到bootstrap 0.12.0.

尝试:

<li class="dropdown">
   <a href class="dropdown-toggle clear">

请记住,当您将其升级到版本0.12.0或更高版本时,它们已删除了对指令的类限制,并且它们将根据使用的角度版本进行默认指令限制.因此,您需要切换回现在的方式.有关详细信息,请参阅此答案.

似乎问题的原因可能是因为您从官方网站引用了演示,但使用旧版本的bootstrap.
