我的Handlebars文件看起来有点像这样:
{{#each book in view.bookcase}}
{{view App.BookView classBinding="book.read:read:unread"}}
{{/each}}
我想在book-id="1"
的曲调或者当前图书的ID中添加一个属性,但我不知道如何。如果我试试这个......
{{#each book in view.bookcase}}
{{view App.BookView book-id="book.id" classBinding="book.read:read:unread"}}
{{/each}}
...然后该属性字面上被设置为“book.id”。有什么想法吗?

嗯,起初我认为根据this post和this post允许使用attributeBindings
,但是当我尝试这样做时,我会收到此错误:
Uncaught Error: assertion failed: Setting 'attributeBindings' via Handlebars is not allowed. Please subclass Ember.View and set it there instead.
所以我认为现在最好的方法是在课堂上进行。
车把模板:
<script type="text/x-handlebars">
{{#each book in view.bookcase}}
{{view App.BookView classBinding="book.read:read:unread" contentBinding="book"}}
{{/each}}
</script>
扩展课程:
App.BookView = Ember.View.extend({
attributeBindings: ['book-id'],
'book-id': function() {
return this.content.id;
}.property('content.id')
});
