shift + tab的关键代码是什么？ [英] what is the key code for shift+tab?

问题描述

我正在进行键映射。问题是，当我按Tab键时，它将导航到下一个输入字段。

I am working on key mapping. The problem is that when I press the TAB button down it navigates to the next input field.

TAB键为9， >
DOWN的键是40

TAB has key of 9 and
DOWN has key of 40

但是，什么是JavaScript键码转到前一个输入字段（SHIFT + TAB）？

But, what is the JavaScript key code to go to the previous input field (SHIFT + TAB)?

我想要的是去下一个链接;什么是以前的链接的键码或代码？

What I want is to go to next link; what is keycode or code for the previous link?

请帮忙。

Please help. Thanks.

推荐答案

有没有 键码，这是一个事件对象的单独属性，如下所示：

There's no "keycode", it's a separate property on the event object, like this:

if(event.shiftKey && event.keyCode == 9) { 
  //shift was down when tab was pressed
}
