ng-switch 不适用于 md-tabs

ng-switch not working with md-tabs

我正在尝试使用 ng-switch 创建条件 md-tabs。 我知道 ng-if 可以正常工作,但我非常感谢 ng-switch-default 因为没有 ng-else.

举个例子html:

<div ng-controller="all">
  <select ng-switch="var">
    <option value="t1">Type 1</option>
    <option value="t2">Type 2</option>
  </select>
  <md-tabs ng-switch="var">
    <md-tab ng-switch-when="t1" label="{{tab.label}}" ng-repeat="tab in tabs">
      <!-- content for tabs using type 1 -->
    </md-tab>
    <md-tab ng-switch-when="t2" label="{{tab.label}}" ng-repeat="tab in tabs">
      <!-- content for tabs using type 2 -->
    </md-tab>
  </md-tabs>
</div>

和脚本:

angular.module('app', ['ngMaterial'])
.controller('all', function($scope, $element) {
  $scope.tabs = [
    {label: 'tab1'}, 
    {label: 'tab2'}];
});

我也用这个例子写了this codepen。 我做错了什么?

你需要包裹在一个div,

演示

<html>

<head>
  <title>angular material switch</title>
  <link rel="stylesheet" href="//rawgit.com/angular/bower-material/master/angular-material.css">
</head>

<body>
  <div ng-app="app" ng-controller="ctrl">
    <md-input-container>
      <md-select ng-model="selected">
        <md-option value="t1">Type 1</md-option>
        <md-option value="t2">Type 2</md-option>
      </md-select>
    </md-input-container>



    <div ng-switch="selected">
      <div ng-switch-when="t1">
        <md-tabs>
          <md-tab label="{{tab.label}}" ng-repeat="tab in tabs">
            <!-- content for tabs using type 1 -->
          </md-tab>
        </md-tabs>
      </div>
      <div ng-switch-when="t2">
        <md-tabs>
        <md-tab label="{{tab.label}}" ng-repeat="tab in tabs">
          <!-- content for tabs using type 2 -->
        </md-tab>
        </md-tabs>
      </div>
    </div>

  </div>
