如何给FormPanel表单中的元素赋值以及获取表单元素值

1.定义表单元素的name属性如下

       var HLV = new Ext.form.TextField({fieldLabel: '汇率',name:'EXCHANGERATE',anchor: '30%'});

2.定义数据源

       var ExchangeRatestore= new Ext.data.Store({proxy: new Ext.data.HttpProxy({ url: 'WsECOTAX01.asmx/SelectExchangeRate', method: "post" , async: false }),reader: new Ext.data.XmlReader({totalProperty: 'totalRecords',record: 'row'}, [{ name: 'EXCHANGERATE' }])});

3.定义赋值方法

        function DataToFormExchange(value) {ExchangeRatestore.load({ params: { DOCNO: value} });var rsData = ExchangeRatestore.getRange(0, 0);if (rsData.length == 0) {return false;}PformPanel.getForm().loadRecord(rsData[0]);return true;}  

4.获取表单值的方法

PformPanel.getForm().getValues()

得到的是一个表单对象，后台用相应的实体对象接收（或作为参数）
