Question

代码： -

{ "Projects": [
 {
    "ProjectName" : "SmarTest",
    "ProjectDescription" : "abc",
    "ModuleDetails": [
        {
           "Maintitle":"Getting Started with IoT1"
        },{
           "Maintitle":"Getting Started with IoT2 "
        }]
  },
  {

    "ProjectName" : "SmarTest",
    "ProjectDescription" : "abc",
    "ModuleDetails": [
         {
          "Maintitle":"Getting Started with IoT3"
        },{
           "Maintitle":"Getting Started with IoT4"
        }
      ]
   }
]}

这是我的样本JSON，现在我希望使用 ng-repeat （IoT1入门和IoT3入门）从每个ModuleDetails的第一个阵列获取主标题显示它。

我试过

<div ng-repeat="Module in Projects.ModuleDetails">
  <div>{{Module[0].MainTitle}}</div>
</div>

Answer 1

Check this plunkr, I think this is what you looking for

使用类似的内容：

<div ng-repeat="ob in data.Projects">
  <div ng-repeat="a in ob.ModuleDetails">{{a.Maintitle}}</div>
</div>

<!DOCTYPE html>
<html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>
<body>
<div ng-app="myApp" ng-controller="myCtrl"> 
<div ng-repeat="x in mdata.Projects">
  <p>{{x.ModuleDetails[0].Maintitle}}</p>
</div>
</div>
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope, $http) {
$scope.mdata = {"Projects":[
            {"ProjectName" : "SmarTest","ProjectDescription" : "abc","ModuleDetails":[{"Maintitle":"Getting Started with IoT1"},{"Maintitle":"Getting Started with IoT2"}]},
            {"ProjectName" : "SmarTest","ProjectDescription" : "abc","ModuleDetails":[{"Maintitle":"Getting Started with IoT3"},{"Maintitle":"Getting Started with IoT4"}]}
   ]}
});
</script>
</body>
</html>

使用ng-repeat从JSon获取数据并显示它
