Javascript, determine if an href click is a call to javascript function or not

Question

I'm tying in to the onbeforeunload event in Javascript to disable control of the page during the unload process. We have a bunch of users who were editing data during this time and it was wreaking havoc on the product.

There are a bunch of links that show up on the page that have href="javascript:....." .

Clicking these links fires the disabling code, which makes the page impossible to use. Is there a way I can detect if the onbeforeunload event is navigating to a different page or just firing this Javascript?

Answer 1

Have every href link visit a piece of javascript code which does inspection on the href contents before it is executed.

event.target.href.startsWith('javascript')

If yes, submit the request, if not, do something else.

Answer 2

这不是最可靠的检查方法，但它适用于我的目的：

$('*:focus').attr('href')
