Javascript regex test() error: Object has no method 'test'

Question

I cant get the javascript test() method to work, I keep getting an error, this regular expression is working fine when using the match() function.

This is my JS:

reg="^(?:https?://)?(?:www.)?(?:youtube.com|youtu.be)(?:/)(?:watch?v=)?([^&]+)";

ytl=$('#yt').val();    //this is just an input value
if(reg.test(ytl)){
    alert('works');
}

This is the error I keep getting:

Uncaught TypeError: 
Object ^(?:https?://)?(?:www.)?(?:youtube.com|youtu.be)(?:/)(?:watch?v=)?([^&]+) 
has no method 'test'

Any ideas?

The test method is defined on RegExp objects. Try this:

var reg = /^(?:https?:\/\/)?(?:www.)?(?:youtube.com|youtu.be)(?:\/)(?:watch?v=)?([^&]+)/;

Or this:

var reg = RegExp("^(?:https?://)?(?:www.)?(?:youtube.com|youtu.be)(?:/)(?:watch?v=)?([^&]+)");

Interesting, so much to learn with JavaScript, when I have no issues with PHP, seems so much more finicky, just my inexperience however. That works perfectly, thanks.
