Overload IPhone GO button to take action

I am developing an application using html and javascript. I have a login form with a login button. The text field accepts the username, and then clicks the login button, the login action occurs. However, now I want that when using the virtual keyboard in the iPhone, pressing the GO button should also trigger the login action. Please let me know the solution for the same. Thanks.

Set a delegate object for the UITextField object (point to your view controller) and use the method

- (BOOL)textFieldShouldReturn:(UITextField *)textField

-textFieldShouldReturn will be called immediately before the user who the user types “Go” or “Return”. Remember to return YES.
