Here is my contribution to the "please wait" examples. This combines Mickey Grackins javascript, and Ruben Ruedas "please wait" page with a slight difference that I think is an improvement.

One disadvantage of Ruben's approach is that a page is inserted into the browser history. This sort of thing affects the behaviour of the browser "back" button, and is something to be avoided (at least with my customers :-)). Mickeys method avoids the spurious page being placed in the browser history.

Here is my code. The javascript is excerpted from a larger library as is shown here:

// ----------------------------------------------------------------------
// pleasewait: display a "please wait" message in a window.
// ----------------------------------------------------------------------

function pleasewait ()
{
var features = 'height=100,width=400';

var url = '/baseapp/plswait.htm';

window.open(url, 'plswait', features);
}


Here is Rubens modified HTML page:

<html>
<head>
<title>
Please Wait
</title>
</head>
<body onblur="self.close();">
<center>
<table border=0 cellpadding=0 cellspacing=0 width="250"><tr><td>
<table cellpadding=2 cellspacing=1 border=0 width="100%"><tr><td>
<center>
<font size="2" face="Verdana, Arial, Helvetica, sans-serif">Cargando datos</font>
<br><img src="path/to/progress.gif" border="0" width="200" height="26"><br>
<font size="2" face="Verdana, Arial, Helvetica, sans-serif">Espere por favor...
</font>
</center>
</td>
</tr>
</table>
</td></tr>
</table>
</center>
</body>
</html>


One difference is the addition of the onblur="self.close()" on the body tag. This causes the "please wait" window to be closed when the window goes out of focus. Normally this will occur when the query results are returned to the user.

Just thought I'd try to keep the threed going a little longer!

I recently tried to incorporate this functionality into an application and succesfully used the code posted by Francis and was very pleased. However, it will only work properly (so far as I have found) on machines using IE 6 browsers. When using IE7, the

body onload="init();window.opener.document.wcf1.submit();"

does not seem to work. The Please wait page pops up, but the job is never submitted to WF.

Anyone had the same experience or know what the problem may be?


Regards,

Darin

I haven't dared upgrade to Vista or IE 7 so I don't have an opportunity to test th JS, but I'll try it on Firefox, Safari and whatever other web browser I have around.


Meanwhile, based on a completely unrelated issue (perhaps not so unrelated?) I found I could make something work by delaying execution for a few milliseconds. I haven't tried this yet for the Please wait message, but give this a try, the init and submit run after a 250 millisecond delay (it adds a quarter second to the process, increase the time a bit if that doesn't work, it is also possible it won't work at all):

body onload="setTimeout('init(); window.opener.document.wcf1.submit();', 250);"

or try delaying the submit after the delay:

body onload="init(); setTimeout('window.opener.document.wcf1.submit();', 250);"


Perhaps this may work because it gives the web browser time to execute the init function before the form submit. I don't have any knowledge of the intricacies of web browsers.

Another approach to running multiple onload events is to use attachEvent:
function addEvent(obj, evType, fn){
 if (obj.addEventListener){
    obj.addEventListener(evType, fn, true);
    return true;
 } else if (obj.attachEvent){
    var r = obj.attachEvent("on"+evType, fn);
    return r;
 } else {
    return false;
 }
}
addEvent(window, 'load', init);
addEvent(window, 'load', function() {
 document.getElementById('submitForm').submit()
});

which is x-browser compliant.
(though the DX Transforms are IE only)

Darin,


you can try using plain JavaScript call somewhere on the bottom of your HTML, for example:
<script>
window.opener.document.wcf1.submit();

A complete example, tested on IE 6 and Firefox 2:
A simple "Please Wait" message WITH an animated image!

So to open this thread, again...
Several years later we now have a automatic "Loading, Please wait..." message supplied when ever a fex is run in an iframe.
Does any one know how to turn this message off?
Can it be done for one iframe (a small one where this message gets garbled) but not for others on the page?
Thanks, G
