如何关注野生动物园中特定的非形式元素？

Question

Is it possible to use javascript to focus anywhere but the URL if the focus is on the single form element on the page and the use presses Tab ? There's a setting "press tab to highlight each item on a webpage", which does allow to do exactly that by default, but is there a way to force such behavior without that setting?

Answer 1

You just need to set the tabindex property on any element to make it focusable.
