@SuperScript While this answer is a bit bare in terms of explanation, it is still valid. – keeehlan Mar 16 '15 at 20:41
@shruggernaut: Tiny code snippets are better as comments. It looks like the right code; explain a little on what it does and you'll be good. – Robbie Wxyz Mar 16 '15 at 20:43
@SuperScript They're better as comments when they are intended as a comment, perhaps on somebody else's answer, but if this were posted as a comment on the question, you could rest assured that somebody might come along and request that they post it as an answer. – keeehlan Mar 16 '15 at 20:45
@shruggernaut: while they work, code-only answers are not likely to be useful to future users. [See](http://meta.stackoverflow.com/q/258673/2619939) [these](http://meta.stackexchange.com/q/95470/241819) [meta](http://meta.stackexchange.com/q/146865/241819) posts. – Robbie Wxyz Mar 16 '15 at 20:54

Try the following regex: \?page=\d+:

var url = 'dashboard/permissions?page=2';
alert(url.match(/\?page=\d+/));

And to remove it :

if(url.match(/\?page=\d+/)!==null) {
    url=url.replace(/\?page=\d+/, "");
    alert(url);
}
//returns "dashboard/permissions"
