We are creating one application in which we pick a form from other website and show it on our website. Once the user fills the form and clicks on submit data is submitted 3rd website. This requirement is one of our application specific. With help axaj we have done so far.

Now the problem is javascript validation. where user fills the form validation does not works. Again form on 2nd website comes from website one using ajax. can any one know why or let ne know if you need any details.

Sounds like a JavaScript problem. You'll probably get better replies in the JS forum.

You'll need to retrieve the JavaScript that does the form validation also. Most form validation JS will register event handlers on the forum elements. You'll need to make sure this is also done. Usually its done by calling a single function in the javascript (if its well written).
