我正在使用 Node.js+Express 编写一个 Web 应用程序来服务(使用 HoganJs 作为模板引擎)和前端的 AngularJS。我在 ng-repeat 渲染正确数量的元素时遇到问题,但没有任何内容。我将 ng-repeat 分解为一个较小的示例,但它仍然没有渲染。
编辑:Plunkr 中有一个错字,所以我删除了它。这是我的应用程序中更扩展的摘录。
以下是我观点的一部分:index.hjs
<div class="search-results" ng-controller="results">
<ul class="tracks">
<li class="track" ng-repeat="track in tracks">
<ul class="meta">
<li>
<div class="name">
<span class="value">{{track.name}}</span>
</div>
</li>
<li>
<div class="album">Album:
<span class="value">{{track.album}}</span>
</div>
</li>
<li>
<div class="artist">Artist:
<span class="value">{{track.artist}}</span>
</div>
</li>
<li>
<div class="length">Length:
<span class="value">{{track.length}}</span>
</div>
</li>
</ul>
</li>
</ul>
</div>
结果控制器:js/controllers/results.js
var results = function($scope, socket) {
$scope.tracks = [
{"uri":"spotify:track:1jdNcAD8Ir58RlsdGjJJdx","name":"Ho Hey","artist":"The Lumineers","album":"The Lumineers"},
{"uri":"spotify:track:3uuGbRzMsDI5RiKWKOjqWL","name":"Hey Porsche","artist":"Nelly","album":"Hey Porsche"},
{"uri":"spotify:track:5BSndweF91KDqyxANsZcQH","name":"Ho Hey","artist":"The Lumineers","album":"The Lumineers"},
{"uri":"spotify:track:2UNc0duOP4cS7gqYFFkwxT","name":"Hey Girl","artist":"Billy Currington","album":"Hey Girl"},
{"uri":"spotify:track:6fgbQt13JlpN59PytgTMsA","name":"Snow [Hey Oh]","artist":"Red Hot Chili Peppers","album":"Snow [Hey Oh]"}
];
socket.on("results", function(tracks) {
$scope.tracks = tracks;
console.dir(JSON.stringify($scope.tracks));
});
$scope.add = function(uri) {
socket.emit("add", uri);
};
};
最后是我的模块:app.js
var app = angular.module("app", []);
var factories = {
socket: socket
};
app.factory(factories);
var controllers = {
actions: actions,
search: search,
results: results,
queue: queue
};
app.controller(controllers);
出于测试目的,当应用程序运行 5li
秒时,轨道被硬编码,但其中没有任何内容被模板化。
