XmlHttp (Ajax) Show Waiting Message

[Grant Merwitz]

Hi

I have a form that submits to a web service.
As this takes time, i would like to show the user a loading message while
its loading.
I am using XmlHttp to do the request
How can i show this waiting message.
No matter what i do, it waits till everythings loaded before doing anything.

Currently:

<SCRIPT language="javas cription">

function ButtonClick()
{
ShowLoadingMess age();
SubmitXmlHttpRe quest();
}

function ShowLoadingMess age()
{
document.getEle mentById('statu smessage').inne rHTML = 'Loading ...';
}

var xhttp;

function SubmitXmlHttpRe quest()
{
xhttp = new ActiveXObject(" Msxml2.XMLHTTP" );
xhttp.onreadyst atechange = GetXmlHttpResul t;
xhttp.open("GET ", http://mydomain.com/WebPageThatDoesProcessing,
false);
xhttp.send();
}

function GetXmlHttpResul t()
{
if ( xhttp.readyStat e == 4 )
document.getEle mentById('statu smessage').inne rHTML = 'Submitted';
}

</SCRIPT>

TIA

for the browser to update the display it needs to run a windows look
(doevents). you go into a hard loop and prevent this. try:

function ButtonClick()
{
ShowLoadingMess age();
window.setTimeo ut("SubmitXmlHt tpRequest();",1 );
}

Thanks Bruce, i'll give that a try.

I had previously tried 'setTimeout',
but not 'window.setTime out'
