extjs4.0 MVC 变更proxy的url 以及查询条件

数据模型



Ext.define('WLCSP.ERP.models.CompanyModel',{

    extend:'Ext.data.Model',

    fields:[

        {name:'AutoID',type:'int'},

        {name:'CompanyNO',type:'string'},

        {name:'CompanyName',type:'string'},

        {name:'Tel',type:'string'},

        {name:'Address',type:'string'},

        {name:'AddressEng',type:'string'},

        {name:'Postcode',type:'string'},

        {name:'Remark',type:'string'},

        {name:'Creator',type:'string'},

        {name:'CreatedTime',type:'datetime'},

        {name:'DeletedBy',type:'string'},

        {name:'DeletedTime',type:'datetime'},

        {name:'Deleted',type:'boolean'}

    ]

});

数据源

 

Ext.define('WLCSP.ERP.stores.CompanyStore',{

    extend    : 'Ext.data.Store',

    singleton : true,

    requires  : ['WLCSP.ERP.models.CompanyModel'],

    model     : 'WLCSP.ERP.models.CompanyModel',

    constructor : function() {

        this.callParent(arguments);

        this.loadData([]);

    },

    proxy: {

        type: 'ajax',

        url: 'listCompany.action',

        reader: {

            type: 'json',

            root: 'companylist',

            successProperty: 'success'

        }

    },

    autoLoad: false

});

grid组件



Ext.define('WLCSP.ERP.views.CompanysGridPanel', {

    extend   : 'Ext.grid.Panel',

    alias    : 'widget.CompanysGridPanel',

    requires : ['WLCSP.ERP.stores.CompanyStore'],

    initComponent : function() {

        this.store   = WLCSP.ERP.stores.CompanyStore;  //  grid组件的store已经固定，但需要通过一些查询条件查不同的数据，通过当前的store：WLCSP.ERP.stores.CompanyStore   

        this.columns = this.buildColumns();

        this.callParent();

    },

    buildColumns : function() {

        return [{header:'AutoID',dataIndex : 'AutoID',hidden:true},

            {header:'CompanyNO',dataIndex : 'CompanyNO',width: 70},

            {header:'CompanyName',dataIndex:'CompanyName',width: 70},

            {header:'Tel',dataIndex:'Tel',width:70},

            {header:'Address',dataIndex:'Address',width:70},

            {header:'AddressEng',dataIndex:'AddressEng',width:70},

            {header:'Postcode',dataIndex:'Postcode',width:70},

            {header:'Remark',dataIndex:'Remark',width:70},

            {header:'Creator',dataIndex:'Creator',width:70},

            {header:'CreatedTime',dataIndex:'CreatedTime',width:70},

            {header:'DeletedBy',dataIndex:'DeletedBy',width:70},

            {header:'DeletedTime',dataIndex:'DeletedTime',width:70},

            {header:'Deleted',dataIndex:'Deleted',width:70}];

    }

});

不知道如何去实现proxy,实现功能类似与extjs2的proxy，如下面代码



//数据源提取数据

dsMaterialOutsourcingList.proxy = new Ext.data.HttpProxy({

        url:'MaterialOutsourcingData.jsp?DbType=SearchLoad&PN=' + Ext.getCmp("txt_pn_materialoutsourcingsearch_id").getValue()    

});

dsMaterialOutsourcingList.load({params : {start : 0,limit : 30}});
