class="postTitle">前段时间公司有需求。自己整理一套MVC代替backbone.自己充满热情的写了下。但是现在内牛满面的事情发生了。客户还是觉得用backbone。好吧。。

为了纪念被扼杀在摇篮中的mvc特此记录下。

还不完整。

下面是调用的方法.

view:定义

var trendView = mvc.View.extend({
    el:'#trends',
    template:{
        trendImg:       '<div class="trend-img">'                               
    },
    changeFn:{
        trendInfo:function(){

        }
    },
    enevtsFn: {
        displayditTrends:function(e){
            e.stopPropagation();
            e.preventDefault();
            var $ele = $(this).find('.trend-img div');
            e.type == 'mouseover' ? $ele.show() : $ele.hide(); 
        }
    },
    remove:function(){
    },
    events:function(){
        var that = this,
            enevtsFn = that.enevtsFn;
        $('#trends').find('.trend-content').unbind().bind('mouseover mouseleave',enevtsFn.displayditTrends);
    },
    render:function(){
        var that = this,
            model = that.model;
        var $div = $('<div class="trend-content"></div>');
        aInnerHtml.push(trendImg_T);
        
        that.events();//bind enevts
    },
    change:function(key){
        this.changeFn[key]();
    },
    initialize:function(model){
        this.model = model;
        //this.render();
    }
});

放上去的时候去掉某些敏感代码

model定义：

var trendsModel = mvc.Model.extend();
var _model = new trendsModel({
    sadas:{
        'dasdasd':{
            trendName:'test',
            editorName:'blue',
            trendDescription:'just test'
        } 
    }
});
var _model1 = new trendsModel({
    sadas:{
        'dasdasd':{
            trendName:'test1',
            editorName:'blue11',
            trendDescription:'just test'
        } 
    }
});

Collection使用：

var trendList = mvc.Collection.extend({
    arrayView : [],
    render:function(){
        var aView = this.getArrayView() || [],
            len = aView.length;
        if(len > 0){
            for(var i = 0;i<len; i++){
                var view = aView[i];
                view.render();
            }
        }
    },
    initialize:function(){
    }});
var _trendList = new trendList();
_trendList.add(_model1,trendView);
_trendList.add(_model,trendView);
_trendList.render();
