Feb 14.2007

hello everyone

i’ trying to build a script that reads to a variable the content of an invisible iframe after being loaded from a url.
so the final result would be a variable (or several variables) with the text/html the intire file downloaded in the iframe.
is it possible to do that?

thx in advance

@slaughtersFeb 14.2007 — Use the innerHTML function on the iFrames ID

i.e. var StoredHTML = document.getElementById("[I]iFrames ID[/I]").innerHTML;

Additionally as konithomimo stated. The iFrame and the main page you are doing this from need to be on the same server

I'm curious. How would AJAX help at all in getting an IFrames HTML? How could using XMLHttpRequest to send Asynchronous server side commands do you any good what so ever in this case?

P.S. FF means FireFox web browser.
