我是AngularJS的新手。也许我的问题会很愚蠢。请提前。
我有index.html:
<html>
<head>
<link rel="stylesheet" href="bower_components/bootstrap/dist/css/bootstrap.min.css">
<link rel="stylesheet" href="bower_components/angular/angular-csp.css">
<script src="bower_components/angular/angular.js"></script>
<script src="bower_components/angular-route/angular-route.js"></script>
<script src="js/controllers.js"></script>
<script src="js/app.js"></script>
</head>
<body ng-app="app">
<div>
<div ng-view></div>
</div>
</body>
</html>
app.js:
'use strict';
angular.module('app', ['ngRoute', 'controllers'])
.config(['$routeProvider', function ($routeProvider) {
$routeProvider
.when('/', {
templateUrl: "templates/home.html",
renderOnFirstLoad: false
});
}]);
controllers.js:
'use strict';
var controllers = angular.module('controllers',[]);
controllers.controller('HomeCtrl', ['$scope', function ($scope) {
$scope.friends = {'name': 'name1', 'picture': {'data': {'url': 'url1'}}};
}
])
和templates / home.html
<div class="container-fluid" ng-controller="HomeCtrl" ng-cloak>
<ul class="friends">
<li ng-repeat="friend in friends" class="thumbnail">
<div>
<img src="{{friend.picture.data.url}}"/>
</div>
<p>{{friend.name}}</p>
</li>
</ul>
</div>
当我打开应用程序时,有两个 li 项目,但我在friends变量中只使用一个值。我该如何解决这个问题?
答案 0 :(得分:2)
使用$scope.friends
作为数组:
'use strict';
var controllers = angular.module('controllers',[]);
controllers.controller('HomeCtrl', ['$scope', function ($scope) {
$scope.friends = [{'name': 'name1', 'picture': {'data': {'url': 'url1'}}}];
}
])
html代码:
<div class="container-fluid" ng-controller="HomeCtrl" ng-cloak>
<ul class="friends">
<li ng-repeat="friend in friends" class="thumbnail">
<div>
<img src="{{friend.picture.data.url}}"/>
</div>
<p>{{friend.name}}</p>
</li>
</ul>
</div>
