Javascript在平板电脑上阅读按键？ [英] Javascript read keypresses on tablet?

问题描述

我有这个有趣的问题 - 我想使用javascript阅读按键，但没有直接进入文本字段。

I have this interesting problem - I would like to read keypresses using javascript, but not directed into a text field.

这在计算机上很简单，我有工作（只要窗口有焦点，javascript就可以检测到按键）。但是，在运行Android和iOS的平板电脑上，操作系统会忽略按键。如果我专注于文本字段，javascript代码只会收到按键数据。

This is straightforward on computers and I have that working (As long as the window has focus, the javascript can detect keypresses). However, on tablets running Android and iOS, the operating system ignores the keypresses. The javascript code only receives the keypress data if I am focused in a text field.

有什么方法可以解决这个问题吗？我想阅读平板电脑上的按键，而不必专注于文本字段。

Is there some way around this? I would like to read the keypresses on tablets without having to be focused in a text field.

推荐答案

尝试这样的事情：

 $('input,textarea').on("keypress", function (e) {
    //do any action here
 });
