View Full Version : Dashcode Ajax request issue.

Jul 12, 2007, 11:01 AM
I have been trying to create a widget to request a server and display the number of email messages you have using Dashcode.

However, the XMLHTTP request object seems to be aborting before doing anything. The readystate property is set to 4 and the status is set to 0, According to what I have discovered from the internet, this means it has aborted. I am sure my URL is correct, yet it still won't work.

Here is my code:

var xmlhttp = create_object(); //this creates the xmlhttprequest object, I know this works as its been tested in browsers, safari (3), firefox and IE
xmlhttp.open('POST', 'http://boshty.co.uk/mail/list_messages.php', true);
xmlhttp.onreadystatechange = function()
if (xmlhttp.readyState == 4)
if (xmlhttp.status == 200)
//request worked
//error, this is where we always end up. Ready state 4, status 0.
xmlhttp.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded'); //because we are sending data
xmlhttp.send("f=inbox"); //this needs to be sent.

Thanks in advance :)

You didn't say what error you were getting my guess is you ran into a cross-domain issue.

you can google for cross-domain widget or xmlhttprequest etc. Yahoo has a pretty good diagram of what is going on there is several techinques to get around it.

It seems XMLHTTP Request object gives no error. It just aborts.

Is there any way I can extract an error from it?

Make sure you are allowing for network access in your Info.plist file:
