IBM Worklight - 如何在更新应用程序之前执行JavaScript代码？ [英] IBM Worklight - How can I execute JavaScript code before updating the application?

问题描述

当有新的软件更新可用时，如果用户将数据存储在jsonstore中，我需要允许用户在应用软件更新之前将它们提交到服务器，因此他/她的未经更新的更新不会丢失。
目前用户在安装更新之前无法使用该应用程序。

When a new software update is available, if user has data stored in jsonstore I need to allow user to commit them to the server before applying the software update, so his/her uncommited updates don't get lost. Currently user is unable to use the application until the update is installed.

有没有办法在更新应用程序之前执行JavaScript代码，这样我就可以初始化jsonstore，在执行更新安装之前获取数据并发送到适配器？

Is there a way to execute JavaScript code before updating the application so I can initialize the jsonstore, take the data and send to the adapter before performing the update installation?

推荐答案

我们看到卸载和 beforeunload事件在DirectUpdate之前被触发。如果数据在那个时间点仍然可以在内存中使用，这可能是代码选项吗？

We saw that the "unload" and "beforeunload" events are fired before a DirectUpdate. Maybe this is an option for code if the data is still available in memory at that point in time?
