regex to check url not works

i added below regex to check if it is url:

function checkurl(url){
var regex = /^(https?:\/\/)?([\da-z\.-]+)\.([a-z\.]{2,6})([\/\w \.-]*)*\/?$/;
if(!$.trim(url).match(regex)){
        //alert("Not Valid Url");
        alert('Not Valid Url');
        return false;
}

this works for most of url but for below url it shows error:

You need to add few more characters in your last character class to support query string i.e. ?, &, and =:

^(https?:\/\/)?([\da-z\.-]+)\.([a-z\.]{2,6})([?=&\/\w \.-]*)*\/?$

It doesn't work for that URL because it has a query string (?v=wEQi87xSIgU).

Add this before $:

(\?[^#]*)?(#.*)?

This will match query strings, and hashes.

^(https?:\/\/)?([\da-z\.-]+)\.([a-z\.]{2,6})([?=\/\w \.-]*)\/?$

                                              ^^          ^^

Try this.See demo.Added ?= to character class.Also removed *)* which would result in catastrophic backtracking.
