我试图在表中显示来自JSON的嵌套数据但是没有成功。
我的 json 数据: -
$scope.data = [
{
"$id": "1",
"Folder": [
{
"Name": "Windows-Desktop",
"CPU": "2",
"RAM": 2,
"FolderName": "Folder-28"
},
{
"Name": "Desktop",
"CPU": "1",
"RAM": 1,
"FolderName": "Folder-11"
}
]
}
]
我在控制器中尝试了这个: -
$scope.Folder = [];
angular.forEach($scope.data.Folder, function(choose) {
$scope.Folder.push(choose);
}
在视图中,我这样做了
<tbody>
<tr role="row" class="odd">
<td class="sorting_1" ng-repeat="g in Folder">{{g.Name}}</td>
<td>
<div ng-repeat="g in Folder">
<input class="form-control" type="text">{{g.CPU}}</input>
</div>
</td>
<td>
<div ng-repeat="g in Folder">
<input class="form-control" type="text">{{g.RAM}}</input>
</div>
</td>
</tr>
</tbody>
我没有得到任何输出。我哪里错了?

在您的控制器中,请执行以下操作:
$scope.Folder = [];
angular.forEach($scope.data, function(choose) {
if(choose && choose.Folder){
$scope.Folder.push(choose.Folder);
}
})

您需要在控制器中使用$scope.data[0].Folder
,因为$scope.data
是一种数组类型。而且我不确定你是如何渲染你的表格的,但问题只与获取$scope.Folder
中的值有关,这是你的解决方案。
var myApp = angular.module('myApp', []);
//myApp.directive('myDirective', function() {});
//myApp.factory('myService', function() {});
function MyCtrl($scope) {
$scope.data = [
{
"$id": "1",
"Folder": [
{
"Name": "Windows-Desktop",
"CPU": "2",
"RAM": 2,
"FolderName": "Folder-28"
},
{
"Name": "Desktop",
"CPU": "1",
"RAM": 1,
"FolderName": "Folder-11"
}
]
}
];
$scope.Folder = [];
angular.forEach($scope.data[0].Folder, function(choose) {
$scope.Folder.push(choose);
});
}
&#13;
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="MyCtrl">
<tbody>
<tr role="row" class="odd">
<td class="sorting_1" ng-repeat="g in Folder">{{g.Name}}</td>
<td>
<div ng-repeat="g in Folder">
<input class="form-control" type="text" />{{g.CPU}}
</div>
</td>
<td>
<div ng-repeat="g in Folder">
<input class="form-control" type="text" />{{g.RAM}}
</div>
</td>
</tr>
</tbody>
</div>
&#13;
这是我认为是你期待的另一个例子
var myApp = angular.module('myApp', []);
//myApp.directive('myDirective', function() {});
//myApp.factory('myService', function() {});
function MyCtrl($scope) {
$scope.data = [
{
"$id": "1",
"Folder": [
{
"Name": "Windows-Desktop",
"CPU": "2",
"RAM": 2,
"FolderName": "Folder-28"
},
{
"Name": "Desktop",
"CPU": "1",
"RAM": 1,
"FolderName": "Folder-11"
}
]
}
];
$scope.Folder = [];
angular.forEach($scope.data[0].Folder, function(choose) {
$scope.Folder.push(choose);
});
}
&#13;
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="MyCtrl">
<table border='1'>
<tr>
<th>Name</th>
<th>CPU</th>
<th>RAM</th>
</tr>
<tr ng-repeat = "g in Folder">
<td>{{g['Name']}}</td>
<td>{{g['CPU']}}</td>
<td>{{g['RAM']}}</td>
</tr>
</table>
</div>

您正在访问$scope.data.Folder
这是不正确的,因为$scope.data
是一个数组。
首先尝试循环$scope.data
,然后循环Folder
$scope.Folder = [];
angular.forEach($scope.data, function(choose) {
if(choose && choose.Folder && choose.Folder.length) {
angular.forEach(choose.Folder, function(choose1) {
$scope.Folder.push(choose1);
}
}
}

您可以尝试以下
<div ng-repeat="item in data">
<div ng-repeat="g in item.Folder">
Name:{{g.Name}}-
Cpu:{{g.CPU}}-
Ram:{{g.RAM}}
</div>
</div>
使用上述方法将无需在控制器中准备数据

您需要做的就是更新迭代器功能
从
angular.forEach($scope.data.Folder, function(choose)
至
angular.forEach($scope.data[0].Folder, function(choose)
看看你的json文件夹是第一个元素......
