我把我的头发拉出来，我似乎不能让鼠标事件工作后，我的 Backbone.js 视图是重新渲染，除非我做了最荒谬的事情：

$("a").die().unbind().live("mousedown",this.switchtabs);

我实际上有这个在那里，但决定更新到最新的 Backbone ，并尝试使用新的delegateEvents()功能。
下面是我的项目ID的结构：

Appview / AppRouter
  |
  ----->PageCollection
             |
             ------->PageView/PageModel
             ------->PageView/PageModel      these page view/models are not rendered
             ------->PageView/PageModel
             |
             ------->PageView/PageModel
                        |
                        ----->render()      *when a pageview is rendered*
                                |
                                -----> Creates new 
                                     Tabcollection
                                       |
                                       --->TabModel/TabView   <-- this is where the issue is

实际情况是tabcollection有一个主tabview来管理所有的选项卡，然后为每个选项卡创建一个新的模型/视图，并在每次加载选项卡时放置一个侦听器来重新呈现tabview。如果tabview被重新呈现，那么鼠标事件就不再起作用，除非我在其中放置那个人为的jQuery语句。
这是Tabview和渲染（我已经把它剥离了很多）

var TabPanelView = Backbone.View.extend({
    className:      "tabpanel",
    html:           'no content',
    model:          null,
    rendered:       false,
    events:{
        'click a.tab-nav': 'switchtabs'
    },
    initialize: function(args)
    {
        this.nav            = $("<ol/>");
        this.views          = args.items;
        this.className      = args.classname?args.classname:"tabpanel";
        this.id             = args.id;
        this.container      = $("<section>").attr("class",this.className).attr("id",this.id);
        _.bindAll(this);
        return this.el
    },
    /*
    This render happens multiple times, the first time it just puts an empty html structure in place
    waiting for each of the sub models/views to load in (one per tab)
    */
    render: function(args){
        if(!args)
        {
            //first render
            var nav             = $("<aside/>").addClass("tab-navigation").append("<ol/>").attr("role","navigation");
            var tabcontent      = $("<section/>").addClass("tab-panels");
            for(i = 0;i<this.views.length;i++)
            {
                $("ol",nav).append("<li><a rel='"+this.views[i].id+"' href='javascript:;' class='tab-nav'></a></li>");
                tabcontent.append(this.views[i].el);
            }
            this.$el.empty().append(nav).append(tabcontent);
        }
        else if(args && args.update == true){
            // partial render -- i.e. update happened inside of child objects
            var targetid = args.what.cid;
            for(i = 0;i<this.views.length;i++)
            {
                var curcontent  = this.$el.find("div#"+this.views[i].id);
                var curlink     = this.$el.find("a[rel='"+this.views[i].id+"']")
                if(this.views[i].cid == targetid)
                {
                    curcontent.html($(this.views[i].el).html());
                    curlink.text(this.views[i].model.rawdata.header);
                }
                if(i>0)
                {
                    // set the first panel 
                    curcontent.addClass("tab-content-hide");
                }
                if(i==0)
                {
                    curcontent.addClass("tab-content-show");
                    curlink.addClass("tab-nav-selected");
                }
                // this ridiculous piece of jQuery is the *ONLY* this i've found that works
                //$("a[rel='"+this.views[i].id+"']").die().unbind().live("mousedown",this.switchtabs);
            }
        }
        this.delegateEvents();
        return this;
    },
    switchtabs: function(args){

        var tabTarget = args.target?args.target:false
        if(tabTarget)
        {
            this.$el.find("aside.tab-navigation a").each(function(a,b)
            {
                $(this).removeClass("tab-nav-selected")
            })
            $(tabTarget).addClass("tab-nav-selected");
            this.$el.find("div.tab-content-show").removeClass("tab-content-show").addClass("tab-content-hide");
            this.$el.find("div#"+tabTarget.rel).removeClass("tab-content-hide").addClass("tab-content-show");
        }
    }
});

有人能想到为什么 Backbone.js 鼠标事件根本不触发吗？是因为它们不在DOM上吗？我认为这是 Backbone.js 特别有用的地方？...
