how to autofill and auto submit facebook login form

[gamazone]

hi to all
is it possible to auto fill and auto login the facebook login form?

i am developing a web application in which , user will in put his,say for facebook, login information in his home page and upon

clicking a button , facebook will open and entered information will get auto filled in the login form and form will be auto submitted

i tried javascript but, i have doubt , can the document object refer to the facebookpage??
reason to doubt:-
i wrote a script and document.URl in this case containing the name of the my web form , but not of the facebook
code is: this code is within javascript function..and is called upon clicking the button

location.href="https://www.facebook.com";
document.forms[login_form].elements["email"].value("gautam");

where login_from->name of the login form of the face book
email -> name of the email field
gautam-> value to be set to the email field

any sort of guidance will be appreciated

Your JavaScript will not be able to access the facebook login page. There are security measures implemented into web browsers that prevent this type of coding so that malicious code in one page cannot be executed in another page.

That being said, if your web application is meant to allow people to log into facebook, look into using the facebook API to do so :)

thx for replying

sir,is it only the case with facebook?? or every website which needs the login say gmail

I don't know, you'll have to research each application/website that your web application will be interfacing with.

i think it will be possible to auto fill yahoo login form

Big companies that have public web api's often implement some kind of delegated authorization. This is where someone clicks on link to your page, they get redirected facebook's or whoever page to type in their credentials, and get redirected back to where they came from with some type of token that can be used to call whatever apis.

All yahoo sites support OAuth I believe, same with google. Microsoft has something called WLDA (windows live delegated auth).

Facebook javascript API has something you can use.

@ZiadElmalki

thank you sir for replying..

i checked your link, and its very useful i will delve into its depth, but sir
i just come across a code which shows we can access gmail page or any page and can automatically fill and login , so in that case we need not to use the API's here is the link

http://scyanide.com/2009/07/use-c-sharp-to-fill-out-web-forms/

it uses SHDocVw.dll
if this kind of code works?? is it possible

There is an open source library which does similar thing

Check http://www.clipperz.com/

Clipperz is open source so you can see its source code,


best luck,
