我正在开发一个Backbone Web应用程序,我想知道如何从视图中发布数据 这是我的模特:
App.Models.edit = Backbone.Model.extend({
defaults : {
id : undefined,
fname : undefined,
lname : undefined,
phone : undefined,
address : undefined,
email : undefined,
url: undefined,
},
initialize: function(){
this.set({url : '../api/getOne/' + App.CurrentID });
},
getAttrs: function(attr){
return this.get(attr);
}
});
这是我的观点:
App.Views.edit = Backbone.View.extend({
el: $("#modal"),
initialize: function(){
App.TplNames.edit = $('body');
App.Tpls.edit('edit');
this.model.bind("reset", this.render, this);
this.render();
},
events: {
'click .btnSave': 'saveDetails',
},
saveDetails: function(){
this.model.save();
//console.log(this.model);
},
render: function(){
var elem = '';
$.each(this.model.models, function(i, k){
var template = _.template( $('#tpl_edit').html(), k.toJSON() );
elem += template;
});
$(this.el).html(elem);
$("#myModal").modal('show');
$("#myModal").on('hidden', function(){
//alert(123);
document.location.href = App.Url + '#view';
});
var attrs = "";
$.each(this.model.models, function(i, k){
attrs = k.toJSON();
});
$("#fname").val(attrs.fname);
$("#lname").val(attrs.lname);
$("#Email").val(attrs.email);
$("#Phone").val(attrs.phone);
$("#Address").val(attrs.address);
//console.log(attrs);
}
});
这是我的路由器
App.Router = Backbone.Router.extend({
routes: {
"" : "def",
"home" : "def",
"view" : "getAll",
"edit/:id" : "edit",
"add" : "addContact",
},
def: function(){
this.mainModel = new App.Collections.Main();
this.mainView = new App.Views.Main({model: this.mainModel});
//this.mainModel.fetch();
},
edit: function(id){
App.CurrentID = id;
var contactCollObj = new App.Collections.edit();
viewObj = new App.Views.edit({model: contactCollObj});
contactCollObj.fetch();
viewObj.render();
//console.log(contactCollObj);
},
getAll: function(){
//alert(123);
var collObj = new App.Collections.View();
var viewObj = new App.Views.View({model: collObj});
collObj.fetch();
},
addContact: function(){
//var model = new App.Collections.AddContact();
model = new App.Models.AddContact();
var view = new App.Views.AddContact({model: model});
//view.render();
}
});
var app = new App.Router(); Backbone.history.start();
当我想保存模型时,它会产生错误:
this.model.save is not a function
除了以上所有事情都没关系......
答案 0 :(得分:1)
在路由器中,您将集合作为模型传递给App.Collections.edit
视图:
var contactCollObj = new App.Collections.edit();
viewObj = new App.Views.edit({model: contactCollObj});
这就是为什么你不能打电话给save()
。 save()
仅适用于非集合的模型。
您可能希望使用集合
初始化视图viewObj = new App.Views.edit({collection: contactCollObj});
然后还相应地修改一些视图代码。
