我有一个示例登录表单。那里有一个控制器、视图和一个模型。我想验证表单。我的表单面板 ID 是“formPanelLogin”，并且必须更新控制器中的表单记录。但是这段代码“formPanelLogin.updateRecord(teamModel);” 无法工作并出现“updateRecord 未定义”之类的错误消息。请给我这个问题的答案。我的代码将遵循..
//Controller
Ext.define('MyApp.controller.mvcController', {
extend: 'Ext.app.Controller',
config: {
refs: {
BtnSubmit: "#btnSubmit",
BtnCancel:"#btnCancel",
BtnPromoHome:"#PromotionsBtnHome",
BtnThirdBack:"#thirdBtnBack",
BtnSecondBack:"#btnUnderHoodService",
},
control: {
BtnSubmit:
{
tap: "onBtnSubmitTap"
},
BtnCancel:
{
tap: "onBtnCancelTap"
},
BtnPromoHome:
{
tap: "onBtnPromoHomeTap"
},
BtnSecondBack:
{
tap: "onBtnSecondBackTap"
},
BtnThirdBack:
{
tap: "onBtnThirdBackTap"
}
}
},
onBtnCancelTap: function (options)
{
//formPanelLogin.reset();
var teamModel = Ext.create('MyApp.model.MyModel'),
errors, errorMessage = '';
formPanelLogin.updateRecord (teamModel);
errors = teamModel.validate();
if (!errors.isValid()) {
errors.each(function (err) {
errorMessage += err.getMessage() + '<br/>';
}); // each()
Ext.Msg.alert('Form is invalid!', errorMessage);
} else {
Ext.Msg.alert('Form is valid!', '');
} // if
console.log("Cancel");
},
});
//view
