Question

如何在ng-repeat中使用Or条件。我目前有

<div ng-repeat="waterSample in viewRequest.data.REV_SAMPLE_CMQREQUEST_WATER_SAMPLE">

有时可以是viewRequest.data.REV_SAMPLE_CMQREQUEST。它应该寻找viewRequest.data.REV_SAMPLE_CMQREQUEST_WATER_SAMPLE or viewRequest.data.REV_SAMPLE_CMQREQUEST我该如何解决

Answer 1

要获得预期结果，请使用以下三元条件来检查属性：在viewRequest.data中使用REV_SAMPLE_CMQREQUEST_WATER_SAMPLE，并根据条件使用REV_SAMPLE_CMQREQUEST_WATER_SAMPLE或REV_SAMPLE_CMQREQUEST

     <div ng-repeat="waterSample in viewRequest.data.hasOwnProperty('REV_SAMPLE_CMQREQUEST_WATER_SAMPLE')? viewRequest.data.REV_SAMPLE_CMQREQUEST_WATER_SAMPLE : viewRequest.data.REV_SAMPLE_CMQREQUEST">
{{wareSample}}
      </div>

工作代码示例

var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope, $http) {
  $scope.viewRequest = {
    data: {
      REV_SAMPLE_CMQREQUEST_WATER_SAMPLE : [
        {id: 1, name: "test1"},
        {id: 2, name: "test2"}
      ],
      REV_SAMPLE_CMQREQUEST:[
        {id: 100, name: "ABC1"},
        {id: 200, name: "ABC2"}
      ]
    }
  }
  
  $scope.conditionalArr = $scope.viewRequest.data.hasOwnProperty('REV_SAMPLE_CMQREQUEST_WATER_SAMPLE')? $scope.viewRequest.data.REV_SAMPLE_CMQREQUEST_WATER_SAMPLE : $scope.viewRequest.data.REV_SAMPLE_CMQREQUEST
});

<div ng-app="myApp" ng-controller="myCtrl"> 

  <div ng-repeat="waterSample in viewRequest.data.hasOwnProperty('REV_SAMPLE_CMQREQUEST_WATER_SAMPLE')? viewRequest.data.REV_SAMPLE_CMQREQUEST_WATER_SAMPLE : viewRequest.data.REV_SAMPLE_CMQREQUEST">
    {{waterSample.id}} {{waterSample.name}}
  </div>

Answer 2

一种方法是使用ng-show，如下所示：

<div ng-show="viewRequest.data.REV_SAMPLE_CMQREQUEST_WATER_SAMPLE" 
    ng-repeat="waterSample in viewRequest.data.REV_SAMPLE_CMQREQUEST_WATER_SAMPLE">
<div ng-show="!viewRequest.data.REV_SAMPLE_CMQREQUEST_WATER_SAMPLE" 
    ng-repeat="waterSample in viewRequest.data.REV_SAMPLE_CMQREQUEST">

Answer 3

我认为更简单，更干净的方法是在控制器中连接这两个数组，然后在ng-repeat中使用它。

在ng-repeat语句中使用Or条件
