问题描述

其他帖子涉及在表单数据已更改且用户离开 XPage 时使用 XSP._isDirty() 触发 CSJS.似乎不适用于 Domino 9.0.1 FP1.之前的帖子警告说这是一个私人功能，可能会被删除.

Other posts refer to using XSP._isDirty() to trigger CSJS when form data has been changed and the user moves off of an XPage. Doesn't seem to be working with Domino 9.0.1 FP1. Earlier posts warned that it was a private function and may get removed.

Mastering XPages 谈到将 enableModifiedFlag 用于类似目的(但这似乎仅适用于 XPINC).

Mastering XPages talks about using enableModifiedFlag for similar purpose (but this appears to be only for XPINC).

推荐答案

您还可以使用 CSJS 来触发警报，当用户要关闭标签页/浏览另一个 URL/关闭浏览器时

You can also use CSJS to fire an alert, when the user is going to close the tab / browse another URL / close browser

使用 window.onbeforeunload 事件，您可以在其中定义检查文档是否更改的函数
