[PHP] AJAX with POST
Hey all,
At the risk of being told this is a PHP and not a JS list, but
also knowing the discussions on this list, to the benefit of
all I believe, very wildly, I'm posting this JS code snippet
for some advice.
As I posted earlier, my AJAX app that uses a GET to post to
the server (and get a response), fails on IE with larger data,
so I thought I'd take a shot at writing a POST function, but
so far I can get it to get the data back, but the problem is
by the time the data has come back the function has already
returned null back to the calling function. What I need this
function to do is wait for the data to come back and then send
it back to caller. Here's the function. Any advice would be
greatly appreciated. (The code to get the appropriate object
per browser has been omitted.)
http.open(POST, url, true);
//Send the proper header information along with the request
http.setRequestHeader(Content-type,
application/x-www-form-urlencoded);
http.setRequestHeader(Content-length, url.length);
http.setRequestHeader(Connection, close);
http.send(url);
http.onreadystatechange = function() {//Call a function when
the state changes.
if(http.readyState == 4 http.status == 200) {
alert('['+http.responseText+']');
return (http.responseText);
}
}

Skip,
You didn't show the code to build the url variable but I would assume
that since you started with a get method you are tacking data onto the
end of the URL that is the called Ajax page.
I had the same issue at work correcting the VP's mistake of mixing up
post and get in his ajax call. The trick is to build the data
separately from the URL and pass it.
I do an ajax.open(URL) then an Ajax. Send(data) to send just the data.
I can post my entire function set if you want.

Re: [PHP] AJAX with POST
Hey Bastien all,
...D'oh! Thanks for the catch, yes, I am sending args on the
URL. But more to my problem, if I switch to POST will IE be
able to submit more data? If so, I can parse the URL down in
the function and build a proper post transaction, but my real
problem is IE can't submit, apparently, more than 2K through a
GET.
Do you know if POST can handle more?
Thanks tons for your reply!
Skip
PS. I'd very interested in seeing your set of functions.
