如何禁用 md-select

Question

我需要禁用 md-select 但我在 Angular 文档中找不到它。

这是我的代码：

<md-select ng-model="idSelectedMonth" placeholder="Month"> 
    <md-option ng-repeat="month in months" ng-value="month.number">
        {{month.number}}
    </md-option>
</md-select>

Answer 1

您可以在 md-select 标签上使用 ng-disabled="true"，如下所示

(function () {
  'use strict';
   var app = angular.module("App",["ngMaterial"]);


 
    app.controller("ctrl", [function () {
        /* jshint validthis: true */
        var vm = this;

        vm.title = "Hello World !";
        
        vm.items = [
          {id:-1, text:"No Selection"},
          {id:1, text:"Item 1"},
          {id:2, text:"Item 2"},
          {id:3, text:"Item 3"},
          {id:4, text:"Item 4"},
            
          ];
        
        return vm;
    }]);
    
  
})();

    <h1>{{vm.title}}</h1>
    <md-input-container>
      <label>Please choose</label>
      <md-select flex ng-model="vm.selected" ng-disabled="true">
        <md-option ng-value="item" ng-repeat="item in vm.items">
          <span ng-show="item.id>0"> {{item.text}}</span>
          <span ng-show="item.id<0" class="highlight"> {{item.text}}</span>
          </md-option>
      </md-select>
    </md-input-container>
  </div>
  
  
</body>

</html>

您可以检查使用 "false"

制作 ng-disable="true"

Answer 2

ng-disabled 工作正常。这是一个 JSFiddle 演示。

<md-select ng-model="idSelectedMonth" placeholder="Month">
    <md-option ng-repeat="month in months" ng-value="month.number" ng-disabled="true">
        {{month.number}}
    </md-option>
</md-select>

Answer 3

您可以有条件地禁用 md-select 和 md-option

<md-input-container class="md_dropdown">
     <label>--Select--</label>
     <md-select ng-disabled="<condition>" ng-model="vm.selectedValue">
          <div ng-repeat="value in vm.values">
              <md-option 
                 ng-disabled="vm.checkDisabled(value)" 
                 ng-value="value">{{value}}</md-option>
           </div>
     </md-select>
</md-input-container>
