jquery - Javascript regex test() error: Object has no method 'test' - Stack Overflow

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|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|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.|youtu.be)(?:\/)(?:watch?v=)?([^&]+)/;

Or this:

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