How to Change the Text Field of a Remote File with JavaScript?

Suppose:

I made a page that had an IFrame on it.

The IFrame's source file is a remote file.

The main intension is to change the form field values of the IFrame page by running the JavaScript function I made on my page. This means that the IFrame's forms field will filled automatically.

How is it possible....

Please help me.

maybe json could be the answer to your question.
this is where you can find a lot of examples on how to use remote access scripts: http://betterexplained.com/

This will work without security problems if the iframe is in the same domain as the main page. Replace document with the id of the iframe and you can target it easily.

For instance if the id of the input in the Iframe is "box", and the id of the iframe is "theframe"... use this:

Code:

theframe.getElementById("box").value = "v7n ftw";

I need to change the field of a remote file on the IFRAME. Not on the same domain.

I tried many ways. But all results in failure.

So hopping to find a good result from here.

Right... so the Iframe targets a different domain name. You will get a sandbox error if you get close to doing it correctly. It's not possible in any good browser for security reasons. If you could control an iframe that points to a different server, you could do anything you wanted.
