如何使用Javascript防止浏览器声音

Question

I'm using jwerty plugin to handle keyboard events and I created a combination: "alt+a".

It's working well, event firing, but windows's ding! Sound is coming. It's so annoying.

How can I prevent it?

Answer 1

This happens because there is no access key defined for Alt-A. A quick solution is to add something like this to your HTML:

<div accesskey="a"></div>

Here's a Fiddle .
