为什么tabindex =' - 1'阻止键盘 [英] Why tabindex='-1' prevents keyboard

问题描述

经过许多小时试图找出为什么键盘输入不能在引导模式下工作，我终于设法找出问题..这是我永远不会想到的，但通过纯粹的过程发现它淘汰。 $ b

在< div> 上存在 tabindex =' - 1' / code>对于启动时的模式，它会完全停止来自键盘的输入。我原以为数据属性 data-keyboard =false会是罪魁祸首，但事实并非如此。

我的问题
为什么tabindex =' - 1'会阻止键盘输入。除此之外，其目的是什么？

解决方案

tabindex 设置页面上的editable-elements将使用选项卡键迭代的顺序。 -1 看起来像是一个合理的值，从这个意义上说，使一个元素无法接近。

After many hours trying to locate why a keyboard input would not work within a bootstrap modal, i have finally managed to identify the issue.. and it was something i would have never of thought of, but found it by pure process of elimination.

By having tabindex='-1' present on the <div> for the modal from bootstrap, it completely stops the input from the keyboard. I would have thought the data-attribute data-keyboard="false" would have been the culprit however it was not.

My Question Why does tabindex='-1' prevent keyboard input. And what would be its purpose other than that?

解决方案

tabindex sets the order that editable-elements on the page will be iterated using the tab key. -1 seems like a reasonable value, from that sense, to make an element unapproachable.
