Javascript regular expression for URL validation

Question

I want the regular expression to validate the URL with below condition,

1. It should start with http or https
2. It should end with the valid domain. Ex: .com or .in but after the . can have any string. Specially, check whether the . is there and there is a string following the ..

Valid URL: http://www.cnn.com

Invalid URLS:

htt://www.yahoo.com
http://www.yahoo.
http://www.yahoo

I have compose the regular expression as below.

/^(http|https):\/\/[-a-zA-Z0-9+&@#/%?=~_|!:,;]+([\-\.]{1}[-a-zA-Z0-9+&@#/%?=~_|]+)*\.[a-zA-Z]{2,5}(:[0-9]{1,5})?(\/.*)?$/

It worked fine for most of the scenarios.

But if I enter http://www.yahoo didn't validate correctly, but If I enter http://www.google it throws the validation error.

Can anybody please help me to resolve this issue?
