| Hmm... if you're not running Leopard, then the situation I described below is probably not affecting you.
However, there are some changes I would recommend you make to your _javascript_. I can't seem to find any docs on this at the moment, but I'm pretty certain that you must call open() before you call setRequestHeader() for that method to take any effect. So I don't think your calls to setRequestHeader() are having the desired effect.
Also, I would probably trust WebKit to get the content-length header right rather than setting it manually. Especially since it sounds like the error you are getting involves the length of the request, but who knows?
xmlhttp.open('POST', myUrl, true);
xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
That apple doc is really just meant to be an intro to the XMLHttpRequest object (and it's a very good one IMHO). For more a detailed spec, you might try the new W3C working draft:
Hope that helps.

Are you running your widget on a Leopard developer seed or on Tiger?
No, I am not one of those fortunate ones :-)
req.setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); req.send(postData);
If I understand right, this is the way it should be done in Tiger, right? And I did it exactly this way. Here's a snippet of what I wrote:
xmlhttp = false; myRequest = "Param1=" + myP1 + "&Param2=" + myP2 + "&Param3=" + myP3; xmlhttp = new XMLHttpRequest(); xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); xmlhttp.setRequestHeader("Content-length", myRequest.length ); xmlhttp.open('POST', myUrl, true); xmlhttp.> ... }
xmlhttp.send(myRequest);
See docs below for more XMLHttpRequest info:
Speaking about this doc, I have to say that it seems quite incomplete to me, especially as a description of post-requests is missing. That should be updated by Apple, I would say.
I've tried it again and what I got back was the document,containing this text:
This page contains the following errors: error on line 1 at column 1: Extra content at the end of the document Below is a rendering of the page up to the first error.
Just to mention it, I also tried to setrequestheader with "application/xml" with the same result.

Hi,
it's most definitely no _javascript_-error as when I try to send out the post-request I get back a small html-document that contains just some ttags and a text saying something about a "parsererror". I almost believe it is an error-message generated by webkit or whatever it is that is responding to the request. Though I don't know what could have generated this error-message as I tried out a few post-request-examples from the internet and did exactly what they did for generating the request.

what is giving you the parse error? _javascript_? or xmlhttprequest?

Hi all,
I'm new to this list but not to widget-programming in general. And I'm from Germany, so my Englisch might sound a bit strange sometimes.
So, does anybody know why a post-request using XmlHttpRequest could result in a parsererror? Normal get-requests do work fine, but post-request do not though I think I did everything required including setting of headers for parameters like mime-type, length of data that will be sent with the post-request and so on. I am not sure if is a problem with the post-request itself or maybe with the url I use (maybe the result isn't well-formed or something so that might lead to an parsererror?
Btw, I get the same error if I disconnect the internet, so it rather seems as if this is an error-message built into safari or webkit, but even if, I still don't know what causes this error.
Greetings and thanks in advance,
