Question

我正在使用Node.js + Express编写一个Web应用程序（使用HoganJs作为模板引擎）和前端的AngularJS。我遇到了ng-repeat渲染正确数量的元素的问题，但是没有任何内容。我将ng-repeat打破了一个较小的例子，它仍然没有渲染。

编辑：Plunkr中有一个拼写错误，所以我将其删除了。这是我的应用程序中更多扩展的摘录。

以下是我的观点的一部分：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，当应用程序运行时，轨道会被硬编码5 li被渲染但是内部没有内容模板化。

Answer 2

我刚刚意识到这里发生了什么。当页面在服务器上呈现时，Hogan.js会覆盖angular的模板。

Answer 3

只需删除添加到脚本中的额外括号（第19行）。请看这里的脚本。 http://plnkr.co/edit/sy2m0RuXRudGvjnmfC3Y?p=preview
