How to remove "href" using jQuery?
<a id="a$id" onclick="check($id,1)" href="javascript:void(0)" class="black">Qualify</a> After deleting "href", is "Qualification" still clickable?
Your title question and your example are completely different. I will start by answering the title question:
$("a").removeAttr("href"); And if href is not required, the generally accepted way to do this is:
<a href"#" onclick="doWork(); return false;">link</a> Returning false is necessary so that href does not actually go anywhere.

If you want your anchor to still display, you can click:
$("a").removeAttr("href").css("cursor","pointer"); And if you want to remove href only from bindings with certain attributes (for example, those that have only a hash tag like href - this can be useful in asp.net)
$("a[href='#']").removeAttr("href").css("cursor","pointer"); If you remove the href attribute, the anchor will not be configured and will look like plain text, but it will still be clickable.
If you want to remove href, change the cursor and also do not click on it, this should work:
$("a").attr('href', '').css({'cursor': 'pointer', 'pointer-events' : 'none'});
