方法一:(Form 中必须放name与model的字段名称相同的控件) { xtype: 'hiddenfield', name: 'id', id: 'id', hidden: true }var mNewRecord = new IniStore.model.Store();mNewRecord.set('id', this.activeRecord.data.id);mImportForm.loadRecord(mNewRecord);mImportForm.submit({url: '/IniStoreDetail/StoreDetailImport',waitTitle: '温馨提示',waitMsg: '正在导入信息,请稍后...',success: function (form, action) {Ext.Msg.alert('温馨提示', action.result.message);this.getGoodsStore().load();},failure: function (form, action) {Ext.Msg.alert('温馨提示', action.result.message);},scope: this});后台获取: [HttpPost]public string StoreDetailImport(Store mStore){} 或public string StoreDetailImport(){// 设置查询参数var mConditions = new StoreDetail();TryUpdateModel(mConditions); }方法二:(Form 提交的时候设置参数 params) mImportForm.submit({url: '/IniStoreDetail/StoreDetailImport',params: {storeId: this.activeRecord.data.id},waitTitle: '温馨提示',waitMsg: '正在导入信息,请稍后...',success: function (form, action) {Ext.Msg.alert('温馨提示', action.result.message);this.getGoodsStore().load();},failure: function (form, action) {Ext.Msg.alert('温馨提示', action.result.message);},scope: this});后台获取:public string StoreDetailImport(string storeId){}
