Uncaught TypeError: Cannot call method '_trigger' of undefined@H_403_3@ 
 
这是我加载主页所做的.
在routes.js中：
 
  
 
routes:{
    '':'home',}
home:function () {
    new HomeView();
    this.changePage(new HomeContentView());
},changePage:function (page) {
    $(page.el).attr('data-role','page');
    console.log($(page.el));
    page.render();
    $('body').append($(page.el));
    var transition = $.mobile.defaultPageTransition;
    if (this.firstPage) {
        transition = 'none';
        this.firstPage = false;
    }
    $.mobile.changePage($(page.el),{changeHash:false,transition: transition});
}@H_403_3@ 
 
在view.js中
 
  
 
window.HomeView = Backbone.View.extend({
template : Handlebars.compile($('#home').html()),render : function (eventname) {
    this.$el.html(this.template());
    this.header = new HeaderElement();
    this.$el.find('div.header_element').append(this.header.$el);
    this.footer = new FooterElement();
    this.$el.find('div.footer_element').append(this.footer.$el);
    return this;
}
});


window.HomeContentView = Backbone.View.extend({
    initialize: function(options) {
        this.collection = new Fan();
        this.template = Handlebars.compile(tpl.get('elements/home'));
        //~ console.log(tpl.get('home'));
        this.collection.on("reset",this.render,this);
        this.init = true;

        if (this.init) {
            upLimit = 1;
            this.collection.index();
            this.init = false;
        }
    },el: '#home_content_view',render : function (eventName) {
        var self = this;
        var js = (self.collection.toJSON())[0];
        console.log(js);

        $('#home_content_view').html(self.template(js));
        $('#home_content_view').trigger("create");
    }
});@H_403_3@ 
 
在home.html
 
  
 
<div data-role="content">
hi
</div>@H_403_3@
