带开关的角度过滤器列表（角度材料）？

Question

所以我试图过滤我正在重复的列表，使用一个开关来过滤禁用的列表。 off 切换到常规列表。我使用棱角材料作为设计。 i ng-modeled showAll 绑定加载所有列表。我正在使用 asset.disabled 将禁用的那些放在重复中。所以我尝试使用 ctrl.infiniteAssets.disabled。不会工作。

您只需要使用ng-switch 模型并将每个项目的状态作为ng-if 中的条件。你可以直接在md-content中使用md-list和md-list-item。无需使用md-virtual-repeat-container，因为md-content 会在需要时添加滚动条。

这里是 Javascript。

angular.module('myApp',['ngMaterial'])
.controller('TempController',function($scope){
 $scope.tempSwitch = true;
 $scope.data= [
 {name: "Asset 1", status: true},
 {name: "Asset 2", status: true},
 {name: "Asset 3", status: true},
 {name: "Asset 4", status: true},
 {name: "Asset 5", status: true},
 {name: "Asset 6", status: true},
 ];

 $scope.delete = function(item){
 item.status = !item.status;
 }
 $scope.itemClick= function(item){
 console.log(item);
 }
});

HTML 代码。

<body layout="column" layout-fill ng-app="myApp" ng-cloak ng-controller="TempController">

 <div layout="row" layout-align="center end" class="resolvedSwitch">
  <md-switch ng-model='tempSwitch'>
  SHOW-DISABLED
  </md-switch>
</div>
 <md-content layout="column" flex style='background-color:#d1d1d1'>
   <md-list>
     <md-list-item ng-click="itemClick(item)" ng-repeat="item in data" layout-align="start center" ng-show="item.status || tempSwitch">
       <span>{{item.name}} </span>
       <span flex></span>
       <span>{{item.status}}</span>
       <md-button aria-label="Delete Asset" class="md-icon-button md-warn" ng-click="delete(item)">
              <md-icon>D</md-icon>
       </md-button>
       <md-divider></md-divider>
      </md-list-item>
   </md-list>
 </md-content>
</body>

这是Codepen 的工作示例。
