angularjs – FAB快速拨号和简单下拉菜单不起作用

我按照角度材料网站上的说明进行了操作.
https://material.angularjs.org/latest/#/demo/material.components.menu

我遇到的问题是简单的下拉菜单和快速拨号只是静态而不是初始化.

似乎无法弄清楚我错过了什么.

<div layout="column">
  <md-content class="md-padding" layout="column">
    <div class="lock-size" layout="row" layout-align="center center">
      <md-fab-speed-dial md-open="false" md-direction="up"
                         ng-class="md-fling">
        <md-fab-trigger>
          <md-button aria-label="menu" class="md-fab md-warn">
            <i class="fa fa-car"></i>
          </md-button>
        </md-fab-trigger>
        <md-fab-actions>
          <md-button aria-label="twitter" class="md-fab md-raised md-mini">
            <i class="fa fa-car"></i>
          </md-button>
          <md-button aria-label="facebook" class="md-fab md-raised md-mini">
            <i class="fa fa-car"></i>
          </md-button>
          <md-button aria-label="Google hangout" class="md-fab md-raised md-mini">
            <i class="fa fa-car"></i>
          </md-button>
        </md-fab-actions>
      </md-fab-speed-dial>
    </div>
  </md-content>
</div>

我更改了< md-fab-speed-dial>上的ng-class属性.标记为简单的类,它现在有效.看看 this link from the Angular Material site.

在你的情况下,你应该：

<md-fab-speed-dial md-open="false" md-direction="up" class="md-fling">
