用backbone实现的一个MVC的小demo

一、Apache配置

本实例需要使用php支持。要现在Apache中配置虚拟目录，在Apache下的httpd-vhosts.conf文件中添加如下代码

<VirtualHost *:80>
    DocumentRoot "D:/htdocs/backbone_demo"
    ServerName www.backbonedemo.cn
</VirtualHost>

在windows的hosts文件中添加配置，hosts文件的位置在c:\windows\system32\drivers\etc

127.0.0.1       www.backbonedemo.cn

二、文件目录

ajax文件中放置的是php文件，里面记录着一些写死的数据，用于等下做ajax请求返回的假数据。styles放置的是一些简单的CSS。scripts放置的是脚本文件。optimize是通过node.js压缩scripts文件后出现的文件夹，里面存放的也是js脚本。

scripts文件夹下面放置的是MVC的一些文件，以及一些工具文件等。可以参考我的另外一篇博文http://www.cnblogs.com/strick/p/3776335.html，做过一些简单说明。

三、demo操作

1.在上面Apache配置好后输入一个域名，例如我的是www.backbonedemo.cn，显示画。选择不同的类型、版块、分类后到了第二张页面会显示不同的数据内容，但是这里为了做演示，所有就简单操作，只有两种数据，一种是选择类型-》长途，剩下的选择都是另外一种数据了。

四、源码分析

主要的js文件是views文件夹下面的indexView.js、listView.js和model文件夹下面的listModel.js。

1.indexView.js文件主要是在做artDialog的配置，打开弹出层特效。artDialog的介绍可以参考这里http://aui.github.io/artDialog/doc/index.html

 define([
     'jquery',
     'dialogPlus',
     'constUtil'

     index.setKeyWordDialogShow = function() {

         var title = '关键字列表';
         window.dialog = dialog;
         $('#showKeyword').click(function() {
             var link = this;
             var input = $(link).siblings('input[type=text]');
             //var dialog = top.dialog.get(window);
             var transferData = {

             //console.log(transferData);
             top.dialog({
                 url: dialogUrl,
                 title: title,
                 padding: 0,
                 height: 500,
                 width: 900,
                 scrolling: 'auto', //iframe显示滚动条
                 data: transferData, // 给 iframe 的数据
                 onclose: function () {
                     if(!this.returnValue) return;
                     $('#ddlClass option[value='+ this.returnValue.pclass +']').attr("selected", true);
                     $('#ddlModel option[value='+ this.returnValue.pmodel +']').attr("selected", true);
                     $('#ddlType option[value='+ this.returnValue.ptype +']').attr("selected", true);
                     input.val(this.returnValue.txt);
                 }
             }).showModal();
             return false;
         });
     };
     return index;
 });

2.listModel.js主要是做一些数据的验证操作，以及数据的初始化操作

 define(['backbone', 'underscore', 'constUtil'], function(Backbone, _, constUtil) {
     var list = Backbone.Model.extend({
         url: constUtil.domain + constUtil.adminAjaxKeywordUrl,
         defaults: {
             data:{ pclass:'', pmodel:'', ptype:'', txt:''}
         },
         initialize: function() {

         },
         validate: function(attributes, options) {
             if(_.isEmpty(attributes.pclass) || attributes.pclass == 0) {
                 return '请选择类型！';
             }
             if(_.isEmpty(attributes.pmodel) || attributes.pmodel == 0) {
                 return '请选择版块！';
             }
             if(_.isEmpty(attributes.ptype) || attributes.ptype == 0) {
                 return '请选择分类！';
             }
             if(!_.isUndefined(attributes.word) && _.isEmpty(attributes.word)) {
                 return '请输入关键字！';
             }
             if(!_.isUndefined(attributes.key) && _.isEmpty(attributes.key)) {
                 return '请输入关键字类别！';
             }
         }
     });
     return list;
 });

3.listView.js中做的就是整个那个页面的各种逻辑操作：

首先是设置，设置template、el、events

         template: $('#tpl_keyword_list').html(),
         el: '#main',
         events: {
             'click .button_submit': 'setKeyWordReturn',
             'click .button_search': 'search',
             'click #keyword_types a.del': 'delKeywordType',
             'click #keyword_types a.edit': 'editKeywordType',
             'click #keywords a.del': 'delKeyword',
             'click #keywords a.edit': 'editKeyword',
             'click .edit_keyword': 'submitEditKeyword',
             'click .add_keyword': 'addKeyword',
             'click .add_keyword_type': 'addKeywordType',
             'click .edit_keyword_type': 'submitEditKeywordType',
             'change #ddlClass,#ddlModel,#ddlType': 'render'
         },

然后是设置初始化函数，接收从父级页面传来的参数，绑定作用域，设置选中的下拉框，渲染页面

        initialize: function() {
             //获取父级页面传过来的参数
             this.topDialog = top.dialog ? top.dialog.get(window) : this.model.defaults;
             this.requestData = this.topDialog.data;
             this.ddlClass = this.$('#ddlClass');
             this.ddlModel = this.$('#ddlModel');
             this.ddlType = this.$('#ddlType');
             //绑定作用域
             _.bindAll(this, 'render', 'renderWithoutDdl');
             this.setSelected();
             //渲染页面
             this.render();
         },    

接下来是render方法，通过model层请求数据，请求到的数据用Mustache模版填充（Mustache的介绍可以从这里获取到https://github.com/janl/mustache.js/）；获取到的数据动态的修改一个select

     render: function() {
             var _this = this;
             _this.model.fetch({
                 data: $.param(_this.getSelectValues('getKeywords')),//参数变量
                 success: function(model, response) {//成功的情况下返回信息
                     var keywords = response;//返回的信息
                     var html = Mustache.to_html(_this.template, keywords);//模板应用
                     _this.$('dl').remove();//移除原先关键字列表
                     _this.$el.append(html);
                     _this.setKeyWordReference();//选中已选关键字
                     //绑定父级类别下拉列表
                     var types = keywords.DataList;
                     $("#ddlParent option:not(:first)").remove();
                     $("#ddlKeywordType option:not(:first)").remove();
                     _.each(types, function(data) {
                         //console.log(data);
                         var option = string.format('<option value="{0}">{1}</option>', data.KeywordTypeId, data.Name);
                         $('#ddlParent').append(option);
                         $('#ddlKeywordType').append(option);
                     });
                 }
             });
             return _this;
         },

最后就是一些请求操作，一些比较通用的地方做了一些简单的抽象操作如postKeyword、showDialog方法

         addKeyword: function(e) {
             //console.log(e);
             var typeid = $('#ddlKeywordType').val();
             var otherData = {word: $(e.currentTarget).siblings('input[type=text]').val(), typeid: typeid};
             this.postKeyword({operate: 'addKeyword', validate: true, otherData: otherData});
         },
         postKeyword: function(options) {//post提交给服务器
             var _this = this;
             var data = this.getSelectValues(options.operate);
             if(!_.isEmpty(options.otherData)) {
                 _.extend(data, options.otherData);
             }
             if(options.validate) {
                 var msg = this.model.validate(data);
                 if(_.isString(msg)) { //错误提示
                     this.showDialog({content: msg});
                     return;
                 }
             }
             $.post(_this.model.url, data, function(response) {
                 _this.showDialog({content: response.Msg});
                 _this.renderWithoutDdl();
             }, 'json');
         },
         showDialog: function(options) {//提示框
             var defaults = {
                 quickClose: true    // 点击空白处快速关闭
             };
             _.extend(defaults, options);
             defaults.title = options.title || '信息提示';
             defaults.width = options.width || 140;
             dialog(defaults).show();
         }

水平有限还有很多地方需要改进，这里就只做个简单展示操作啦
