当移动safari或chrome上的屏幕键盘打开时，是否有任何javascript事件被触发？ [英] Is there any javascript event fired when the on-screen keyboard on mobile safari or chrome opens?

问题描述

我尝试对Web应用程序中的屏幕键盘做出反应。不幸的是，有些事情使这一点变得复杂：

I try to react to the on-screen keyboard in our web applications. Unfortunately there are some things complicating this:

首先，应用程序必须在移动平台（平板电脑）和台式机上运行。此外，禁止滚动文档/正文并增加更多功能，平板电脑必须使用横向模式。

First of all, the application has to run equally on mobile platforms (tablets) and desktops. Additionally scrolling the document/body is forbidden and to spice things up even more, landscape mode is mandatory on tablets.

因此，如果有人选择任何输入字段，则 - 屏幕键盘打开并阻挡页面一半的视线，因此一些输入变得不可见，我需要更改它。

So, if someone selects any input field, the on-screen keyboard opens up and blocks the sight on half of the page, therefor some inputs become invisible and I need to change that.

不幸的是，似乎没有事件被触发完全，这表明，一半的应用程序刚刚变得不可见。我已经检查了滚动和重新调整事件的大小，但它们也没有触发。

Unfortunately it seems, there is no event fired at all, which indicates, that half of the application just became invisible. I already checked scroll and resize events, but they didn't fire, too.

当然，我总是可以在我确定要开始时以某种方式作出反应平板电脑。可能95％的用户无论如何都不会连接硬件键盘。但是，有没有更清洁的方式？

Of course, I could always react somehow as soon as I'm sure to be on a tablet. Probably 95% of the users will not attach a hardware keyboard anyway. But isn't there any cleaner way?
