扩充ExtJS的【Ext.data.reader.Json】例子

扩展ExtJS的【Ext.data.reader.Json】例子

一，下面是扩展Class

?

Ext.define('Dncsoft.data.MyReader', {    extend: 'Ext.data.reader.Json',    alternateClassName: 'Ext.data.DncReader',    alias : 'reader.dncreader',        startDate: new Date(),    endDate: new Date(),        getResponseData: function(response) {        var me = this;        var data = me.callParent(arguments);        return me.change(data);    },        change: function(sourceJson) {        var me = this;                // filter data and sum value        var map = new Ext.util.HashMap();        for (var i = 0, iEnd = sourceJson.length; i < iEnd; ++i) {            map.add(_id, {"id":_id, "v":_v});        }                return map.getValues();    }});

?

二，这是用扩展Class的地方。

?

var store = Ext.create('Ext.data.JsonStore', {    model: 'Dncsoft.data.MyModel',    buffered: true,    purgePageCount: 0,    proxy: {        type: 'ajax',        url: 'mydata.json',        noCache: true,        filterParam: undefined,        groupParam: undefined,        limitParam: undefined,        startParam: undefined,        sortParam: undefined,        pageParam: undefined,        reader: {            model: 'Dncsoft.data.MyModel',            type: 'dncreader',            root: 'root',            startDate: new Date('1/15/2011'),            endDate: new Date('2/31/2013')        }    },    autoLoad: false});

?
