View .js
(function(window, angular, undefined)

我调用 View 的index.html 索引.html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width">
<title></title>
<link rel="manifest" href="manifest.json">
<link href="lib/ionic/css/ionic.css" rel="stylesheet">
<link href="css/style.css" rel="stylesheet">
<script src="lib/ionic/js/ionic.bundle.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/angular-ui-router/0.4.2/angular-ui-router.min.js"></script>
<script src="cordova.js"></script>
<script src="js/app.js"></script>
<script src="js/components/view/view.js"></script>
</head>
<body ng-app="app">
<ion-pane>
<ion-header-bar class="bar-stable">
<h1 class="title"></h1>
</ion-header-bar>
<ion-content>
<div ui-view>
</div>
</ion-content>
</ion-pane>
</body>
</html>
这是我想显示的view.html view1.html
<div>
<div ng-repeat='pics in pic'>
<p> This is the view.html</p>
<img ng-src={{pic.url}}/>
</div>
</div>
View 没有发生任何事情。我试图获取照片的 View ，但它没有显示任何错误或任何 View 。如果有人可以帮忙的话请!!
最佳答案
在 ajax 中你可以这样写:
$scope.pics=response.data;
但是在你的ng-repeat你的写:
<div ng-repeat='pics in pic'>
更改为
<div ng-repeat='pic in pics'>
关于javascript - 没有错误时什么也没有显示。代码运行良好，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/43300308/
