我从 REST api 收到了以下 JSON 数据。
[
{
"names": {
"en": "test123"
},
"children": [],
"id": "68d87e8c-42f5-4f11-b25a-b30624246c3b",
"version": 1,
"code": "0",
"order": 0,
"country": "HR",
"name": "test123",
"parent": null,
"selected": false,
"hasQuestions": false,
"level": 1,
"state": "original",
"hasChildChapters": false
},
{
"names": {
"en": "test456"
},
"children": [],
"id": "d175e6d1-874e-4909-afb2-790c0a940c3f",
"version": 1,
"code": "0",
"order": 0,
"country": "HR",
"name": "test456",
"parent": null,
"selected": false,
"hasQuestions": false,
"level": 1,
"state": "original",
"hasChildChapters": false
}
]
我正在尝试使用指令 ng-repeat 显示它。通过 object.id 使用跟踪。 它的使用方式如下:
<tr ng-repeat="chapter in chapters | filter: search track by chapter.id">
但问题是ngRepeat:Dupes错误仍然出现。我检查了JSON中包含的数据,但其中没有重复的id。您知道为什么 ngRepeat:Dupes 错误仍然存在吗?
最佳答案
根据给定的数据,没有抛出重复错误,下面是jsfiddle。
<div ng-controller="MainCtrl">
<input type="text" ng-model="search">
<div ng-repeat="chapter in chapters | filter: search track by chapter.id">{{chapter.id}}</div>
</div>
Controller
$scope.chapters = [{
"names": {
"en": "test123"
},
"children": [],
"id": "68d87e8c-42f5-4f11-b25a-b30624246c3b",
"version": 1,
"code": "0",
"order": 0,
"country": "HR",
"name": "test123",
"parent": null,
"selected": false,
"hasQuestions": false,
"level": 1,
"state": "original",
"hasChildChapters": false
}, {
"names": {
"en": "test456"
},
"children": [],
"id": "d175e6d1-874e-4909-afb2-790c0a940c3f",
"version": 1,
"code": "0",
"order": 0,
"country": "HR",
"name": "test456",
"parent": null,
"selected": false,
"hasQuestions": false,
"level": 1,
"state": "original",
"hasChildChapters": false
}]
