问题 I have a website that has colored divs with numbers, e.g. a red block with the number 2 inside of it. The color is important to understanding. A blind user emailed me asking if I could make it say "2 red" for his screen reader. I tried adding this as an alt="2 red" but he said that didn't do anything. He thinks it might only read alt tags for images. Is there a good way to do this for divs? 回答1: As far as alt text, you are correct, that only works for images.. But you can use aria-label in

The second textbox has a tabindex of 1003. When I press tab, the tabindex works fine in all browsers except for Safari, where it immediately moves from the first textbox to the second textbox although the tabindex has been set properly. Any ideas on how to prevent this issue? 回答1: By default tab-access is disabled in

问题 I want to use the Accessibility API to get a list of all windows for a given application (external). The goal is to check if a certain window is open.

问题 Requirement is to distinguish the keypress and mouse click events in Mozilla browser. The condition is that the Mozilla browser should be able to distinguish the events (click and enter) when the NVDA IS TURNED ON 回答1: If you're only looking to distinguish between Enter/Space press and mouse/pointer press, I would probably go for using both an onclick and an onmousedown .
