有人可以指出我在哪里犯了错误吗？
这是一个非常简单的应用程序，旨在打印出 Json 对象数组中的“name”字段，这是通过以下行完成的:
{{ctrl.contact[0].results[0].name.first}} 或
{{ctrl.contact[1].results[0].name.first}}
(这本身看起来很复杂)
我无法让它通过循环单独打印每个 Json block 的名称，这是我尝试过的:
<div ng-repeat="i in ctrl.contact">
<span>{{ctrl.contact[i].results[0].name.first}}</span>
</div>
花了几个小时调整和编辑后，我确信我的 Angular 设置(应用程序、 Controller 等)很好。
代码片段如下:
<html ng-app="ContactAppApp">
<head>
<title>My Contact App</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.5/angular.min.js"></script>
</head>
<body>
<div>
<div ng-controller="ContactAppController as ctrl">
<h1>{{ctrl.test}}</h1>
<div ng-repeat="i in ctrl.contact">
<span>{{ctrl.contact[0].results[0].name.first}}</span>
</div>
</div>
</div>
</body>
<script>
var app = angular.module("ContactAppApp", [])
app.controller("ContactAppController", ContactAppController);
function ContactAppController() {
this.test = "This text is generated by Angular";
this.contact = [
{
"results": [
{
"gender": "male",
"name": {
"title": "mr",
"first": "tony",
"last": "cruz"
},
"location": {
"street": "9813 north road",
"city": "edinburgh",
"state": "humberside",
"postcode": "E84 4YD"
}
}
]
},
{
"results": [
{
"gender": "male",
"name": {
"title": "mr",
"first": "Jack",
"last": "cruz"
},
"location": {
"street": "9813 north road",
"city": "edinburgh",
"state": "humberside",
"postcode": "E84 4YD"
}
}
]
}
]
}
</script>
</html>最佳答案
尝试以下操作:
<div ng-repeat="i in ctrl.contact">
<span>{{i.results[0].name.first}}</span>
</div>
