骨干JS在一个元素中显示多个集合<ul>



我想知道是否有可能在一个<ul> -元素内显示多个集合?

例如,当我有多个视图时,在每个视图中我有一个这样的集合:

Collection = Backbone.Collection.extend({
    url: function() {
        return '/path/to/JSON/file';
    }
});

现在我想在同一个<ul> -元素中显示所有的集合这样在我的前端就会输出

<ul>
   <li>Data from Collection 1</li>
   <li>Data from Collection 1</li>
   <li>Data from Collection 2</li>
   <li>Data from Collection 2</li>
   <li>Data from Collection 3</li>
   <li>Data from Collection 3</li>
</ul>

这可能吗?如果是,那怎么做?

Thanks in advance…

好的,在mainView中我有:

Artist.View = Backbone.View.extend({
    template: 'artistchannel',
    beforeRender: function() {
      var artistinstagramCollection = new ArtistInstagram.ArtistInstagramCollection();
      artistinstagramCollection.artist_id = this.artist_id;
      this.insertView('.socialMedia', new ArtistInstagram.View({collection:artistinstagramCollection}));
      artistinstagramCollection.fetch();
      var artisttwitterCollection = new ArtistTwitter.ArtistTwitterCollection();
      artisttwitterCollection.artist_id = this.artist_id;
      this.insertView('.socialMedia', new ArtistTwitter.View({collection: artisttwitterCollection}));
      artisttwitterCollection.fetch();
      var artistfacebookCollection = new ArtistFacebook.ArtistFacebookCollection();
      artistfacebookCollection.artist_id = this.artist_id;
      this.insertView('.socialMedia', new ArtistFacebook.View({collection: artistfacebookCollection}));
      artistfacebookCollection.fetch();

如前所述,每个Collection都绑定到自己的视图:

function (App, Backbone) {
    var ArtistInstagram = App.module();
    ArtistInstagram.View = Backbone.View.extend({
        tagName: 'li',
        template: 'instagram',
        initialize: function() {
            this.listenTo(this.collection, 'all', this.render)
        },
        serialize: function() {
            return this.collection ? this.collection.toJSON() : [];
        }
    });
    ArtistInstagram.ArtistInstagramCollection = Backbone.Collection.extend({
        url: function() {
            return '/myproject/index.php/api/social_feeds/instagram/' + this.artist_id;
        }
    });
    return ArtistInstagram;
}

Twitter和Facebook也是如此。所以我有3个模块

然后在模板artistchannel中有一个部分,我有:

<div class="socialMediaDiv">
    <ul class="socialMedia"></ul>
 </div>
我的HandlebarsJS-HTML模板看起来像:
{{#each this}}
<li>
<a href="{{link}}" target="_blank"><img src="{{title}}" /></a>
<section class="ip">
    <p>{{description}}</p>
    <h3>
        <time class="timeago" datetime="{{pubDate}}"></time>
        {{type}}
    </h3>
</section>
</li>
{{/each}}

当我这样做时,它生成3个<li> -元素,因此结构如下:

<ul>
   <li>
      <li>some results from collection 1</li>
      <li>...</li>
      <li>...</li>
      <li>...</li>
   </li>
   <li>
      <li>some results from collection 2</li>
      <li>...</li>
      <li>...</li>
      <li>...</li>
   </li>
   <li>
      <li>some results from collection 3</li>
      <li>...</li>
      <li>...</li>
      <li>...</li>
   </li>
</ul>

我做错了什么?

顺便说一下,我使用的是backbone的layoutmanager

这当然有可能。当您呈现集合视图时,只需附加到容器元素(el$el),而不是替换它的html。
