ExtJS 4 中Store动态加载数据的问题


var store = new Ext.data.Store({
        model: 'ProductModel',//产品类
        proxy: {
            type: 'ajax',
            url: 'productList',
            root: 'Data',
            actionMethods: { read: 'POST' },
            extraParams: { pageIndex:1, pageSize:10 }
        } 
     });

  1.   

    我按楼上的试了，不行。
    POST改为小写也一样，改成GET也取不到值。还有store.load()中的参数怎么写？

                 var grid = new Ext.grid.Panel({

                     store: teamStore,
                     width: 400, height: 300,
                     title: 'Sports Teams',
                     columns: [

  3.   

    动态参数加载Store.getProxy().extraParams = {
            name: n,
            month: m,
            state: s
        };
      

  4.   

    extjs3用
    store.baseParams = {name:n,month:m};
    store.load();extjs4用
    store.load({params:{name:n,month:m}});
      

  5.   

    render:function(ths,ops){
       var me=this,
           orgTree=me.getUserOrgTree();
       ths.getStore().on('beforeload',function(  store,  operation,eOpts ){
       console.log('----beforeload execed----- ');
           var orgs= orgTree.getSelectionModel().getSelection() ,
           queryParams = {
                   orgid :(orgs!=null&&orgs.length>0)? orgs[0].get('id'): null,
                   loginName:me.getUserQueryForm().down('textfield[name=loginName]').getValue(),
                   realName:me.getUserQueryForm().down('textfield[name=realName]').getValue()
              
           };
       Ext.apply(store.proxy.extraParams, queryParams);
       });
       
       ths.getStore().loadPage(1);
       //this.getUserList().store.loadPage(1);
       },
