如何使用Handlebars.js获取和显示多个骨干集合?我创建了4个json文件,每个文件都分配给自己的集合和模型。
在我的路由器中,我有初始化:
initialize: function () {
this.allcategoryMenuCollection = new AllCategoryMenuCollection();
this.natcategoryMenuCollection = new NatCategoryMenuCollection();
this.intcategoryMenuCollection = new IntCategoryMenuCollection();
this.topcategoryMenuCollection = new TopCategoryMenuCollection();
}
然后我在路线中定义,当您点击特定链接时,您将被重定向到某个页面:
newpage: function () {
this.artistpageLeftMenuView = new ArtistpageLeftMenuView({el:'#leftMenu'});
this.artistpageLeftMenuView.collections = {
allcategoryMenuCollection: this.allcategoryMenuCollection,
natcategoryMenuCollection: this.natcategoryMenuCollection,
intcategoryMenuCollection: this.intcategoryMenuCollection,
topcategoryMenuCollection: this.topcategoryMenuCollection
};
this.artistpageLeftMenuView.render();
}
我的HTML文件是:
<ul class="sbm2">
{{categoryAll}}
{{#each .}}
<li>
<a href="{{this.url}}">{{this.name}}</a>
</li>
{{/each}}
</ul>
<ul class="sbm2">
{{categoryNat}}
{{#each .}}
<li>
<a href="{{this.url}}">{{this.name}}</a>
</li>
{{/each}}
</ul>
<ul class="sbm2">
{{categoryAll}}
{{#each .}}
<li>
<a href="{{this.url}}">{{this.name}}</a>
</li>
{{/each}}
</ul>
<ul class="sbm2">
{{top100}}
{{#each .}}
<li>
<a href="{{this.url}}">{{this.name}}</a>
</li>
{{/each}}
</ul>
在我的Backbone View中我有:
render: function() {
$(this.el).html(this.template({categoryAll:this.collections.allcategoryMenuCollection.toJSON()}));
$(this.el).append(this.template({top100:this.collections.topcategoryMenuCollection.toJSON()}));
$(this.el).append(this.template({categoryNat:this.collections.natcategoryMenuCollection.toJSON()}));
$(this.el).append(this.template({categoryInt:this.collections.intcategoryMenuCollection.toJSON()}));
return this;
}
我不知道它是什么,但是它向我展示了html模板4次,没有任何内容?!?!
答案 0 :(得分:0)
我不确定我明白你要做什么。因为我的解决方案很简单。 我会像这样制作模板:
<ul class="sbm2">
{{#each allcategoryMenuCollection}}
<li>
<a href="{{this.url}}">{{this.name}}</a>
</li>
{{/each}}
</ul>
<ul class="sbm2">
{{#each natcategoryMenuCollection}}
<li>
<a href="{{this.url}}">{{this.name}}</a>
</li>
{{/each}}
</ul>
<ul class="sbm2">
{{#each intcategoryMenuCollection}}
<li>
<a href="{{this.url}}">{{this.name}}</a>
</li>
{{/each}}
</ul>
<ul class="sbm2">
{{#each topcategoryMenuCollection}}
<li>
<a href="{{this.url}}">{{this.name}}</a>
</li>
{{/each}}
</ul>
用以下方式渲染:
render: function() {
$(this.el).html(this.template(this.collections.toJSON()));
return this;
}
