Question

我想知道是否有可能有这样的事情：

div ng-repeat="(k,v) in items"
<div ng-if="k == 'a' || k == 'b'">
    <!-- SOME CONTENT -->
</div>

知道项目是通过请求收到的JSON容器，这就是我使用键值方法的原因。

由于

我问，因为我尝试使用谷歌搜索，但我能得到的唯一结果是ng-switch，但我必须使用ng-if。

Answer 1

当然可以。类似的东西：

<强> HTML

<div ng-controller="fessCntrl">    
     <label ng-repeat="(key,val) in list">
       <input type="radio" name="localityTypeRadio" ng-model="$parent.localityTypeRadio" ng-value="key" />{{key}}
         <div ng-if="key == 'City' || key == 'County'">
             <pre>City or County !!! {{$parent.localityTypeRadio}}</pre>
         </div>
         <div ng-if="key == 'Town'">
             <pre>Town!!! {{$parent.localityTypeRadio}}</pre>
         </div>        
      </label>
</div>

<强> JS

var fessmodule = angular.module('myModule', []);

fessmodule.controller('fessCntrl', function ($scope) {

    $scope.list = {
        City: [{name: "cityA"}, {name: "cityB"}],
        County: [{ name: "countyA"}, {name: "countyB"}],
        Town: [{ name: "townA"}, {name: "townB"}]
      };

    $scope.localityTypeRadio = 'City';
});

fessmodule.$inject = ['$scope'];

OR运营商：

<div ng-repeat="k in items">
    <div ng-if="k || 'a' or k == 'b'">
        <!-- SOME CONTENT -->
    </div>
</div>

尽管阅读起来很简单，但我希望作为开发人员，你使用的名字比“＆＃39; ＆＃39; K＆＃39; ＆＃39; B＆＃39;等。

例如：

<div class="links-group" ng-repeat="group in groups" ng-show="!group.hidden">
    <li ng-if="user.groups.admin || group.title == 'Home Pages'"> 
        <!--Content-->
    </li>
</div>

另一个OR示例

<p ng-if="group.title != 'Dispatcher News' or group.title != 'Coordinator News'" style="padding: 5px;">No links in group.</p>

AND运算符（对于那些寻求AND而不是OR条件的Stackoverflow应答的绊脚石）

<div class="links-group" ng-repeat="group in groups" ng-show="!group.hidden">
    <li ng-if="user.groups.admin && group.title == 'Home Pages'"> 
        <!--Content-->
    </li>
</div>

HTML代码

<div ng-app>
<div ng-controller='ctrl'>
    <div ng-class='whatClassIsIt(call.state[0])'>{{call.state[0]}}</div>
    <div ng-class='whatClassIsIt(call.state[1])'>{{call.state[1]}}</div>
    <div ng-class='whatClassIsIt(call.state[2])'>{{call.state[2]}}</div>
    <div ng-class='whatClassIsIt(call.state[3])'>{{call.state[3]}}</div>
    <div ng-class='whatClassIsIt(call.state[4])'>{{call.state[4]}}</div>
    <div ng-class='whatClassIsIt(call.state[5])'>{{call.state[5]}}</div>
    <div ng-class='whatClassIsIt(call.state[6])'>{{call.state[6]}}</div>
    <div ng-class='whatClassIsIt(call.state[7])'>{{call.state[7]}}</div>
</div>

JavaScript代码

function ctrl($scope){
$scope.call={state:['second','first','nothing','Never', 'Gonna', 'Give', 'You', 'Up']}


$scope.whatClassIsIt= function(someValue){
     if(someValue=="first")
            return "ClassA"
     else if(someValue=="second")
         return "ClassB";
    else
         return "ClassC";
}
}
