ng-if 里面的 ng-repeat 没有过滤我的数组答案

【问题描述】：

大家好，我正在尝试在我的类型数组中显示带有值的选项卡，其中有

[{"label":"wlan1","type":"wlan1"},
 {"label":"br-wlan","type":"br-wlan"},
 {"label":"tun_cas","type":"tun_cas"},
 {"label":"nfacct_bytes","type":"nfacct_bytes"},
 {"label":"wlan0","type":"wlan0"},
 {"label":"lte0","type":"lte0"},
 {"label":"nfacct_packets","type":"nfacct_packets"}]

在我看来，我不想显示 nfacct_bytes 和 nfacct_packets 类型，为此我正在这样做：

<tab ng-if="type.label !== 'nfacct_bytes' || type.label !== 'nfacct_packets'" 
     ng-repeat="type in dataGraph.network.types" heading="{{type.label}}"
     select="changeSubTab(type.type)" disable="!tabClick" >

解决办法：

<tab ng-if="type.label !== 'nfacct_bytes' && type.label !== 'nfacct_packets'" 
     ng-repeat="type in dataGraph.network.types" heading="{{type.label}}"
     select="changeSubTab(type.type)" disable="!tabClick" >

【解决方案1】：

我认为你需要这样检查，

<tab ng-if="type.label !== 'nfacct_bytes' && type.label !== 'nfacct_packets' "> 
</tab>

演示

var myApp=angular.module('myApp',[]);
 myApp.controller('thecontroller',function($scope){
       $scope.dataGraph = {};
       $scope.dataGraph.network = {};
         $scope.dataGraph.network.types = [{"label":"wlan1","type":"wlan1"},{"label":"br-wlan","type":"br-wlan"},{"label":"tun_cas","type":"tun_cas"},{"label":"nfacct_bytes","type":"nfacct_bytes"},{"label":"wlan0","type":"wlan0"},{"label":"lte0","type":"lte0"},{"label":"nfacct_packets","type":"nfacct_packets"}];
});

            </div>
            </div>

我做了什么也没发生，同样的问题...我有 7 个标签，我只想要 5 个
@ricardol 检查更新的答案。你需要使用 &&

【解决方案2】：

使用angularJS的filter功能。它从数组中选择项目的子集并将其作为新数组返回。

在过滤器中，表达式可以是字符串、对象或函数。这里我使用了表达式作为对象。

让控制器变成这样

  app.controller('MainCtrl', function($scope) {
    $scope.Values = 
     [{"label":"wlan1","type":"wlan1"},
     {"label":"br-wlan","type":"br-wlan"},
     {"label":"tun_cas","type":"tun_cas"},
     {"label":"nfacct_bytes","type":"nfacct_bytes"},
     {"label":"wlan0","type":"wlan0"},
     {"label":"lte0","type":"lte0"},
    {"label":"nfacct_packets","type":"nfacct_packets"}];
});

所需的 HTML

  <div ng-repeat="value in Values |filter: {type: '!nfacct_bytes'}">
      {{value.label}}
  </div>
