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 is a very popular method of adding JavaScript functions to HTML links.
For example: the [Print] links that you see on many webpages are written like this:

Print

Why do we need href while onclick alone can get the job done? Because when users hover over the text 'Print' when there's no href, the cursor will change to a caret (ꕯ) instead of a pointer (👆). Only having href on an a tag validates it as a hyperlink.

An alternative to href="javascript:void(0);", is the use of href="#". This alternative doesn't require JavaScript to be turned on in the user's browser, so it is more compatible.
