本文介绍如何利用XFA中的messageBox进行调试，并展示如何使用saveXML方法保存当前节点类的XML结构为字符串。此外，还提供了获取当前日期的方法。

1.Debugging Calculations and Scripts(messagebox)

用途：调试Javascript时，可以使用messagebox（消息框）提供的反馈信息。缺点之一是user必须关闭很多消息框。

Example:

FormCalc

xfa.host.messageBox(Concat("The value of NumericField1 is: ", NumericField1), "Debugging", 3)

JavaScript

xfa.host.messageBox("The value of NumericField1 is: " + NumericField1.rawValue, "Debugging", 3);

var result = xfa.host.messageBox($record.language.errorMessage.ErrorMsg_SaveEvent.value,"Confirmation",2,2);

2.获取当前日期

Example:

var currentDate = new Date();

app.alert(currentDate);

Result:

var currentDate = new Date();
var year = currentDate.getFullYear();
var month = currentDate.getMonth() + 1;
var day = currentDate.getDate();
var hour = currentDate.getHours();
var minute = currentDate.getMinutes();
