我在 Ember.js 应用程序中有简单的视图,就像这样。每个“内容”元素由两个对象组成,第一个和第二个:
{{#each App.myController.content}}
{{view for content.first}}
{{view for content.second}}
{{/each}}
我想在另一个把手模板脚本中分别为每个内容定义视图(以免不必写两次)。如何将第一个和第二个变量传递给视图?
这是一个代码示例,请参阅http://jsfiddle.net/Zm4Xg/5/:
车把:
<script type="text/x-handlebars" data-template-name="contact-view">
<div>{{name}}</div>
<img {{bindAttr src="avatar"}} {{bindAttr alt="name"}}>
</script>
<script type="text/x-handlebars">
{{#each App.contactsController.pair}}
<div class="menu_vertical_group">
{{#with this.first}}
{{view App.contactView}}
{{/with}}
{{#with this.second}}
{{view App.contactView}}
{{/with}}
</div>
{{/each}}
</script>
JavaScript :
App = Ember.Application.create();
App.Contact = Em.Object.extend({
name: null,
avatar: null
});
App.contactView = Ember.View.extend({
templateName: 'contact-view'
});
App.contactsController = Em.ArrayController.create({
content: [],
initData: function(data) {
var contacts = data.map(function(contact) {
return App.Contact.create({
"name": contact.name,
"avatar": contact.avatar
});
});
this.pushObjects(contacts);
},
pair: (function() {
content = this.get('content');
var result = [];
for (ii = 0; ii < content.length; ii += 2) {
result.pushObject({
"first": content[ii],
"second": content[ii + 1] ? content[ii + 1] : null
});
}
return result;
}).property('content')
});
App.contactsController.initData([{
"name": "John Doe",
"avatar": "/john.jpg"},
{
"name": "Someone Else",
"avatar": "/else.jpg"}]);
