Backbone.js的提取网址与子像

Question

所以我使用Backbone.js的这样：

window.TicketCollection = Backbone.Collection.extend({ 
    model:Tickets, 
    url:"/index.php/tickets/viewJSON" 
}); 

根据网页上我想传递一个子文件夹，如下所示：

ticketList.fetch({ data: "a1103" }); 

这将然后从下面的追加到url和获取数据：

/index.php/tickets/viewJSON/a1103

这怎么可能？

Answer 1

window.TicketCollection = Backbone.Collection.extend({ 
    subFolder : 'defaultFolder', 

    url:function(){ 
     return "/index.php/tickets/viewJSON/" + this.subFolder; 
    } 
}); 

var some = new window.TicketCollection(); 
some.subFolder = 'a1103'; 
some.fetch();
