What does “[removed]void(0)” mean?

Question

login

I\'ve seen such hrefs many times, but I don\'t know what exactly

Answer 1

It means it’ll do nothing. It’s an attempt to have the link not ‘navigate’ anywhere. But it’s not the right way.

You should actually just return false in the onclick event, like so:

hello

Typically it’s used if the link is doing some ‘JavaScript-y’ thing. Like posting an AJAX form, or swapping an image, or whatever. In that case you just make whatever function is being called return false.

To make your website completely awesome, however, generally you’ll include a link that does the same action, if the person browsing it chooses not to run JavaScript.
