jQuery Youtube URL Validation with regex

I know there is plenty of question answered over here http://stackoverflow.com/questions/tagged/youtube+regex, but not able find a question similar to me.

Any body has the JavaScript Regular expression for validating the YouTube VIDEO URL's line below listed. Just want to know where such a URL can be possible

http://www.youtube.com/watch?v=bQVoAWSP7k4
http://www.youtube.com/watch?v=bQVoAWSP7k4&feature=popular
http://www.youtube.com/watch?v=McNqjYiFmyQ&feature=related&bhablah
http://youtube.com/watch?v=bQVoAWSP7k4


-- update 1--
-- update 2--

This one worked almost fine, but failed for the URL http://youtube.com/watch?v=bQVoAWSP7k4

var matches = $('#videoUrl').val().match(/http:\/\/(?:www\.)?youtube.*watch\?v=([a-zA-Z0-9\-_]+)/);
if (matches) {
alert('valid');
} else {
alert('Invalid');
}

Answer
^http:\/\/(?:www\.)?youtube.com\/watch\?v=\w+(&\S*)?$

//if v can be anywhere in the query list

^http:\/\/(?:www\.)?youtube.com\/watch\?(?=.*v=\w+)(?:\S+)?$
