Backbone笔记

入职新的公司，公司前端使用Backbone进行开发。这里记录下Backbone使用教程及技巧。Backbone框架是个成熟又小巧的前端MVC库。

Backbone.View(视图)

reander：默认实现是没有操作的



//html代码

    <div id="search_container"></div>

    	<script type="text/template" id="search_template">

        	<div>

            <%= search_label %>

        </div>

    </script>

//js代码

	 var SearchView = Backbone.View.extend({

                initialize: function () {},

                render: function (context) {

                    console.log($(this.el))

                        //使用underscore这个库，来编译模板

                    var template = _.template($("#search_template").html());

                    //加载模板到对应的el属性中

                    $(this.el).html(template(context));

                }

            });

            var searchView = new SearchView({

                el: $("#search_container")

            });

            //这个reander的方法可以放到view的构造函数中

            //这样初始化时就会自动渲染

            searchView.render({

                search_label: "搜索渲染111"

            });

Backbone.Collection（集合）

add：向集合中添加一个模型
where：返回集合中所有匹配所传递 attributes（属性）的模型数组
fetch()：用于从服务器接口获取集合的初始化数据，覆盖或追加到集合列表中
create()：在集合中创建一个新的模型，并将其同步到服务器



var appModel = Backbone.Model.extend({

    initialize: function(){

        //alert(this.get("test"));

    },

    defaults:{ //缺省值

        test: '1111'

    }

})

//new appModel;

var appCollection = Backbone.Collection.extend({

    modle: appModel //指定模型

})

var appModel1 = new appModel({test: '2222'})

var appModel2 = new appModel({test: '333333'})

var appModel3 = new appModel({test: '44444'})

//添加到集合中

var book = new appCollection([appModel1,appModel2,appModel3]) 

//each取数据

book.each(function(book){

    console.log(book.get('test'))

})
