This question is an exact duplicate of:

• How to send data from Domain 1 input type='text' to Domain 2 input type='text' [closed]

How can i insert a value to another domain (not have access to this domain) textbox, from filling a form from my domain?

Form in my domain:

<form action="" method="post" name="birthdaysend">
 <input type="text" value="" name="birthday" >
 <input type="submit" value="submit">
</form>

Where this value will be shown in the other domain textbox (where i do not have access)

<form action="" method="post" name="birthdayreceive">
 <input type="text" value="" name="birthdaydate" >
 <input type="submit" value="submit">
</form>

When i fill birthday date from my form, on submit the same date to be shown in this other textbox where i do not have access.

</div>

Answer 1

Imagine the other domain is your visitor's online banking and that the text box is where you put the account number to transfer money to.

Now, for obvious security reasons, what you want it entirely impossible.
