我正在尝试从我在本地Web服务器上测试的静态json文件中读取json数据,但是使用$ http.get()服务无法显示任何内容。我在这里查看了一些其他类似的问题,但所有接受的答案都考虑了promise方法的使用,但是对于angularjs v1.6.x +这些已被折旧。
最初我尝试在控制器内部的变量上设置我的json数据,一切正常,但是一旦我移动到JSON文件,没有任何显示。我的第一个错误是我不知道JSON文件是ANSI格式,因为JSON.parse()角度调用能够工作。在将文件编码切换为ANSI之前,我遇到了语法错误,我的json结构是正确的。 (像Dreamweaver这样的文本编辑器将以UTF-8格式创建JSON文件。)
此时,当我检查网页时,控制台上没有任何JS错误,但根本没有数据出现。这是我有的: 我的events.json
[
{
"day" : "Monday",
"objective" : "Pipeline",
"sessions" : [
{
"title" : "Leadership Excellence Luncheon",
"start" : "11:30am",
"end" : "1:00pm",
"location": "room A"
},
{
"title" : "Veteran Resume Workshop",
"start" : "1:15pm",
"end" : "2:00pm",
"location": "room B",
"speakers" : [
{
"name": "John Doe",
"title": "Analyst",
"company": "Appel",
"headshot" : "http://placehold.it/119x134.jpg",
"bio": "john-doe/",
},
{
"name": "Jane Doe",
"title" : "VP",
"company": "Lancer",
"headshot" : "http://placehold.it/119x134.jpg",
}
]
}
]
},
{
"day" : "Tuesday",
"objective" : "Pipeline",
"sessions" : [
{
"title" : "Leadership Excellence Luncheon",
"start" : "11:30am",
"end" : "1:00pm",
"location": "room A"
},
{
"title" : "Veteran Resume Workshop",
"start" : "1:15pm",
"end" : "2:00pm",
"location": "room B",
"speakers" : [
{
"name": "John Doe",
"title": "Analyst",
"company": "Appel",
"headshot" : "http://placehold.it/119x134.jpg",
"bio": "john-doe/",
},
{
"name": "Jane Doe",
"title" : "VP",
"company": "Lancer",
"headshot" : "http://placehold.it/119x134.jpg",
}
]
}
]
}
}
这是我的app.js
(function() {
var app = angular.module('Agendas',[]);
app.controller('TableController', ['$scope', '$http',
function($scope,$http) {
$scope.title = "test";
$scope.events = [];
$http({
method: 'POST',
url: 'http://localhost/ang/data/events.json',
}).then( function(response) {
$scope.events = response;
});
}]);
})();
这是我的index.html
<!doctype html>
<html>
<head>
.....
</head>
<body>
....
<div id="agenda" class="mainCont container-fluid well" ng-app="Agendas" ng-controller="TableController">
<div id="day" ng-repeat="event in events">
<h1>{{ event.day }} — {{ event.objective }}</h1>
<div id="sess" ng-repeat="session in event.sessions">
<div style="width: 140px; float: left; clear: left;">{{ session.start }} - {{ session.end }}<br><br><em>Location: {{ session.location }}</em></div> <div style="float: left;"><em>{{ session.title }}</em> <br>
<div class="panelist" ng-repeat="speaker in session.speakers"><img ng-src="{{ speaker.headshot }}"><br>
<a ng-href="{{ speaker.bio }}">{{ speaker.name }}</a><br>

</div>
</div>
<div class="aghr"></div>
</div>

我注意到您的JSON文件包含一些错误。它可能是相关的。
]
代替}
。 {
"name": "John Doe",
"title": "Analyst",
"company": "Appel",
"headshot" : "http://placehold.it/119x134.jpg",
"bio": "john-doe/", <--- remove comma
}
您可以使用jsonlint网站来验证您的JSON。
**根据建议,您可能必须先清除浏览器缓存。
**另外更改
$scope.events = response;
到
$scope.events = response.data;
