无法访问JSON属性值

Unable to access JSON property values

本文关键字：属性 JSON 访问      更新时间：2023-09-26

这让我抓狂，我知道我一定错过了一些非常简单的东西！

我有一个返回JSON对象的服务：

[{"accountId":"0000004000006195","title":null,"firstName":"JOE","middleName":"BLOG","lastName":"BLOGGS","suffix":null,"primaryAddress":{"addressLine1":"TEST ADDRESS CLOSE","addressLine2":null,"addressLine3":"MY TOWN","town":"Washington","county":null,"country":"US","postcode":"PO9868"},"customerTelephones":[{"phoneNumber":"09876543455","type":"Alternate 1"},{"phoneNumber":"98654345676","type":"Alternate 2"}],"birthDate":108628400000}]

我正在尝试显示JSON的属性，例如使用显示名字

app.controller('MainCtrl', function($scope) {
  $scope.name = 'World';
  $scope.testJson = [{"accountId":"0000004000006195","title":null,"firstName":"JOE","middleName":"BLOG","lastName":"BLOGGS","suffix":null,"primaryAddress":{"addressLine1":"TEST ADDRESS CLOSE","addressLine2":null,"addressLine3":"MY TOWN","town":"Washington","county":null,"country":"US","postcode":"PO9868"},"customerTelephones":[{"phoneNumber":"09876543455","type":"Alternate 1"},{"phoneNumber":"98654345676","type":"Alternate 2"}],"birthDate":108628400000}]
});

HTML:

<p>{{testJson}}</p>
<p>{{testJson.firstName}}</p>

但由于某种原因，｛｛testJson.firstName｝｝显示为空白！

有什么想法吗？

$scope.testJson是Array，您需要通过索引获取元素，然后通过Object 获取属性

 {{testJson[0].firstName}}

Example

您的testJson似乎是一个数组。所以{{testJson[0].firstName}}应该做到这一点！
