• 自己整理的MVC框架


    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。

    $(function($,win){
        if(!win.mvc){
            var AjaxManage = (function() {
                var instantiated;
                var Ajax = function(){
                    this.oAjaxSetting = {
                        sDataType: 'JSON',
                        sGetType: 'get',
                        //ms
                        iTimeOut: 8000,
                        bAsync:true
                    }
                };
                Ajax.prototype = {
                    fnDoAjax: function(oPts) {
                        oPts = $.extend({}, this.oAjaxSetting, oPts);
                        var url = oPts.url,
                            iTimeOut = oPts.iTimeOut,sGetType = oPts.sGetType,sDataType = oPts.sDataType,
                            oParams = oPts.oParams || null,
                            bAsync = oPts.bAsync;
                        try {   
                            $.ajax({

                }
            }
        }
    }(jQuery,window));

    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();
