Question

我不是那么喜欢JavaScript而且我在尝试将一个简单的JavaScript代码导入 Rhino （https://developer.mozilla.org/it/docs/Rhino）时遇到了很大的问题，这是一个允许执行JS代码的JavaScript实现一个Java应用程序。在我的特定情况下， Rhino 嵌入到 WSO2 ESB （用Java开发的ESB工具）中。

我可以在我的Java \ WSO2 ESB应用程序中执行我的JS代码，但是在尝试创建JavaScript Date 对象时遇到了一些问题。在这种情况下，它无法正常工作。

如果在我的JS代码中我有类似的东西：

var dateCurrentOriginalForecast = new Date('2017-11-09 06:00:00');

如果我将它连接到浏览器但是将其执行到 Rhino 它可以正常工作我在Java控制台中获得以下错误消息：

我也尝试过其他格式，例如：

var dateCurrentOriginalForecast = new Date('2017-11-09 06:00:00');
var dateCurrentOriginalForecast = new Date('2017-11-09T06:00:00.000Z');
var dateCurrentOriginalForecast = new Date('2017-11-09T06:00:00');
var dateCurrentOriginalForecast = new Date('2017-11-09T06:00:00T');

但我仍然得到同样的错误。

为什么呢？问题是什么？我错过了什么？什么是正确的日期格式，可以用于Rhino？

与Date对象和Rhino类似的东西在这里，但没有解决方案：Javascript invalid date in iOS/Android 2.2

Answer 1

有效地说这很奇怪......

尝试使用明确的日期部分：

new Date(year, month, day [, hour, minute, second, millisecond ])

new Date('2017','11','09','06','00','00')

Answer 2

它有Date的不同实现。如果字符串的Date.parse返回NaN，则字符串不会被解释为有效日期，new Date(string)的调用将返回date但InvalidDate。

在其各个部分拆分字符串日期并单独设置，或者使用符合Date要求的字符串日期。

为什么我获得＆＃34;无效日期＆＃34;我尝试将Date对象设置为在Rhino中执行的JS脚本时出错？
