我是骨干的新手，需要你的帮助。我正面临一个我无法加载外部模板的问题。 这是问题：
我有一个home_template.html，其中有一个div需要填充外部模板
<div class="ASContainer" id="asContainerView">
</div>
现在我有一个Homeview.js
define([
'jquery',
'underscore',
'backbone',
'marionette',
'text!templates/home/homeTemplate.html',
'text!templates/home/activityTemplate.html',
'text!templates/compose/composeTemplate.html',
'text!templates/comments/commentsTemplate.html',
'views/home/ActivityListView',
'views/ComposePost/ComposePostView',
'views/ComposePost/WSListView',
], function ($, _, Backbone, Marionette, homeTemplate, activityTemplate, composeTemplate, commentsTemplate, ActivityListView, ComposePostView, WSListView) {
var HomeView = Backbone.View.extend({
el : $("#page"),
transition : 'slide',
activitiesListView : null,
initialize : function () {
this.$el.attr('data-transition', this.transition);
this.currentUserLogin = currentUserLogin;
var that = this;
this.activityId = this.options.activityId;
this.workspaceUrl = this.options.workspaceUrl;
this.context = this.options.parentContext;
},

var that = this;
$('.menu li').removeClass('active');
$('.menu li a[href="#"]').parent().addClass('active');
that.callAjaxReload("homeTemplate.html", "aaa", "AS_Content");
this.$el.html(homeTemplate);
$("#userloggedin").text(currentUserLogin);
//var sidebarView = new SidebarView();
//sidebarView.render();
},

this.undelegateEvents();
$(this.el).empty();

if (activityId <= 0) {
console.log("here");
$("#asContainerView").html(ActivityListView({model : activitiesList}).el);
}
else {
console.log("I am there");
$(new ActivityListView({model : activitiesList}).el).appendTo("#asContainerView");
}
lastactivityId = msgActivities[(msgActivities.length - 1)].ActivityID;
//Add collection to context

},
});
return HomeView;
}）;
现在这个HomeView js有两个功能。 callAjaxReload和getActivitiesForWorkspace。 渲染调用callAjaxReload，它具有ajax函数，成功时调用getActivitiesForWorkspace.Now getActivitiesForWorkspace也有一个ajax函数，并且我必须将模型传递给另一个View ActivityList View并将该模板附加到div id asContainerView下。
我面临的问题是下面的这一行无法加载ActivityListView。
$（“＃asContainerView”）。html（ActivityListView（{model：activitiesList}）。el）;
我收到一个未定义ActivityListView的错误。
任何人都可以帮助我。
ActivityListView.js是
define([
'jquery',
'underscore',
'backbone',
'marionette',
'views/home/ActivityListItemView',
'text!templates/home/activityTemplate.html',
], function ($, _, Backbone, Marionette, ActivityListItemView, activityTemplate) {
var ActivityListView = Backbone.View.extend({
initialize: function () {
this.render();
},
render: function () {
var activities = this.model.models;
var len = activities.length;
//var startPos = (this.options.page - 1) * 8;
//var endPos = Math.min(startPos + 8, len);
var startPos = 0;
var endPos = len;
//$(this.el).html('<ul class="thumbnails"></ul>');
for (var i = startPos; i < endPos; i++) {
{ //$(this.el).append(new ActivityListItemView({model: activities[i]}).initialize);
//console.log("activities[i]:"activityListItemView.model.attributes.ActivityTypeSourceName);
var activityListItemView = new ActivityListItemView({ model: activities[i] });
$(this.el).append(activityListItemView.el);
}
//console.log(activityListItemView.el);
//var personView = new PersonView({ model: person });
}
//$(this.el).append(new Paginator({model: this.model, page: this.options.page}).render().el);
return this;
}
});
}）;
，这会调用ActivityListItemView.js
define([
'jquery',
'underscore',
'backbone',
'marionette',
'text!templates/home/activityTemplate.html',
], function ($, _, Backbone, Marionette, activityTemplate) {
var ActivityListItemView = Backbone.View.extend({
tagName: "div",
template: activityTemplate,
//my_template: _.template(gtemplate1),
//my_template: _.template("<p class=\"AS_Content\"> <%= ActivityContent %> </p> "),
initialize: function(){
this.render();
},
render: function(){ debugger;
//$(this.el).html(this.template(this.model.toJSON()));
this.$el.html(_.template(this.template, { user: this.model.attributes }));
//this.$el( this.template(this.model.toJSON()));
//this.$el.html( this.template(this.model.toJSON()));
}
});
}）;

你有：
$("#asContainerView").html(ActivityListView({model : activitiesList}).el);
但你的语法已关闭;当您想要实例化新的Backbone.View时，您需要使用new关键字：
$("#asContainerView").html(new ActivityListView({model : activitiesList}).el);

您的requirejs定义应返回 ActivityListView和ActivityListItemView
该函数应返回定义模块的对象
