EXTJS 中 两表单元素动态数据怎么实现?

Question

    一个是 combo 另一个是 panel或者textfield
    当 选择 combo 时 从后台获得数据 显示在 panel或者textfield中      在这基础上改 
    
        var openzzfhOpenzzfhForm = new Ext.form.FormPanel({
            id:'openzzfhOpenzzfhForm',
            frame: true,
            layout: 'form',
            labelAlign:'right',
            url: path + "/openzzfhManageCon.do",
            items:[{
                name: 'addczzhzh',
                width: 300,
                fieldLabel: '归属财政专户',
                id: 'iaddczzhzh',
                hiddenName: 'haddczzhzh',
                xtype: 'combo',
                typeAhead: true,
                editable:false,
                triggerAction : 'all',
                selectOnFocus:true,
                forceSelection: true,
                mode: 'local',
                store: czzhzhdsInfoStore,
                displayField: 'zh',
                valueField: 'hm',
                listeners : {
                    specialkey : function(f, e) {
                        if (e.getKey() == e.ENTER || e.getKey() == 40 ) {
                            openzzfhOpenzzfhForm.getForm().findField('addsjzhflag').focus(true,true);
                        }
                    },
                    select : function(combo,record,index) {
                        <!-- 当发生选择事件的时候 就从后台获得数据 显示到下面的panel元素中 -->
                    }
                }
            },{
                name: 'addzh',
                width: 100,
                fieldLabel: zhncStore,
                xtype: 'panel'
            }]
        })
    

Answer 1

我也有同样的问题要问。
我想基本思路的panel弄个datastore，在combo的select函数里给datastore设值，然后再调datastore或panel的refresh方法。但我没有弄出来

Answer 2

解决了 
捕获选择事件 .. 然后
select : function(combo,record,index) {
    //这句是给表单元素赋值
    myForm.getForm().setValues( { '要赋值的表单元素' : 值 } ); 
}
