我想将视图的Model传递给已初始化的View此处。这是包含数据的视图，可以将其视为ItemView的{ {1}}：
Collection这是应该接收数据的var app=app||{};
app.ContactView=Backbone.View.extend({
tagName:'li',
className:['contact-view'],
model:app.Contact,
events:{
'click .editing-icon':'showEditView'
},
initialize:function contactViewInit(){
this.render();
this.listenTo(this.model,'change',this.render);
},
template:Handlebars.templates.contactView,
render:function contactViewRender(){
var html=this.template(this.model.toJSON());
this.$el.html(html);
return this;
},
showEditView:function(){
//show edit view...this should also be handled by app view...
//(1)how do I pass a message to editview;how can I generate an event in Backbone
app.EditView.set({
//there is an error here...
model:this.model
});
}
});
，它基于静态html打开模态并提示用户编辑将重新渲染第一个视图的模型数据，它已经被初始化因为我认为重复初始化没有意义：
View我有 var app=app||{};
var EditView=Backbone.View.extend({
el:'#edit-modal',
initialize:function initializeEditView(){
console.log("Initializing Modal for editing");
console.log(this.model.toJSON());
this.$form=this.$el.find("form");
this.initializeEditForm();
this.showYourself();
},
initializeEditForm:function initializeEditForm(){
this.$form.find('#edit-name').val(this.model.get('name'));
this.$form.find('#edit-email').val(this.model.get('email'));
this.$form.find('#edit-phone').val(this.model.get('phone'));
},
showYourself:function showYourself(){
this.$el.modal('show');
},
hideYourself:function hideYourself(){
clearEditForm();
this.$el.modal('hide');
},
clearEditForm:function clearEditForm(){
this.$form.find('#edit-name').val('');
this.$form.find('#edit-email').val('');
this.$form.find('#edit-phone').val('');
},
events:{
'click #edit-contact button':'submitEditedData'
},
submitEditedData:function submitEditedData(){
var data={
name:this.$form.find('#edit-name').val(),
phone:this.$form.find('#edit-phone').val(),
email:this.$form.find('#edit-email').val()
};
console.log("Data recieved from the edit form");
this.model.set(data);
this.hideYourself();
}
});
app.EditView=new EditView();
处理用html表单创建数据，我应该在那里处理吗？
这是我为了处理创建AppView并将其添加到集合而构建的AppView（这将导致集合视图呈现此项目视图并将其添加到集合中） ：
model答案 0 :(得分：1)
考虑从ContactView触发事件，将事件传递回中央控制器。然后，控制器可以监听此事件并做出相应的反应，即使用从事件中接收的模型实例化EditView。
