如何在angular-material中实现多选选项？

Question

我已经检查了文档和演示，但是天哪！我还没有找到任何实现多选选项的参考，比如使用angular-material的select 2。有没有人能告诉我怎么做？

Answer 1

Splaktar的答案是正确的:只需在md-select中添加多个即可。

工作解决方案的代码：http://codepen.io/ansgar-john/pen/RWPVEO?editors=101

HTML

<div>
  <md-input-container>
    <md-select multiple ng-model="ctrl.likedAnimals" placeholder="please select">
      <md-option ng-repeat="a in ctrl.animals" value="{{a}}">{{a}}</md-option>
    </md-select>
  </md-input-container>
</div>

JS

(function () {
  'use strict';
  angular
      .module('MyApp')
      .controller('AppCtrl', function($scope) {
        this.likedAnimals = ["mouse", "dog"];
        this.animals = ["mouse", "dog", "cat", "bird"];
  });
})();

您也可以应用您自己的自定义模板。

Answer 3

我使用下面的代码来允许我使用ng-repeat和一些md-select，它们是多个的，有些不是(从Angular 1.4.7开始)：

index.html

<md-input-container ng-repeat="item in items track by $index">
        <label>{{item.title}}</label>
            <div ng-include="item.multiselect == 'true' ? 'm_selectfragment.html' : 's_selectfragment.html'"></div>
   </md-input-container>

Javascript

$scope.items = 
        [{title: 'funny',
        selected: '', 
        names: [
            {name: 'some name'}, 
            {name: 'other name'},
            {name: 'more?'}, 
            {name: 'say wha???'}             
            ],
         multiselect: "false"   
        }, 
        {title: 'serious', 
        selected: '', 
        names: [
           {name: 'Obama'},
        {name: 'Trump'},
        {name: 'Hillary'},
        {name: 'Putin'}               
            ],
         multiselect: "true"   
        }];

m_selectfragment.html

<md-select name="item.title" ng-model="item.selected" multiple="true">
<md-option ng-repeat="name in item.names" value="{{name.name}}">{{name.name}}
</md-option>

​

s_selectfragment.html

<md-select name="item.title" ng-model="item.selected">
<md-option ng-repeat="name in item.names" value="{{name.name}}">{{name.name}}
</md-option>
