Hi
I have a form that opens a new window for the results. Because the results
might take a few seconds due to server processing, I would like to display
a message "please wait" in the new window, erase that message when the
processing is done and show the results.
How is this done?

-- on the page used to initate generation of the report:
<input type="submit" value="Generate Report" onclick="openStatusWindow();">
<script type="text/javascript">
function openStatusWindow() {
if (window.open) {
var throwAway = window.open(
'status.html',
'statusWindow',
'width=400,height=200'
);
}
}
</script>
-- status.html:
<html>
<head>
<title>Generating report... please wait</title>
<script type="text/javascript">
function holdFocus() {
var t = setTimeout(holdFocus, 1000);
window.focus();
holdFocus.toString = function() {
return 'holdFocus();';
}
}
</script>
</head>
<body onload="holdFocus();">
<p align="center">Generating report... please wait</p>
</body>
</html>
-- on the page containing the resulting report:
<body onload="closeStatusWindow();">
<script type="text/javascript">
function closeStatusWindow() {
if (window.open) {
var w = window.open(
'about
:blank',
'statusWindow',
'width=400,height=200'
);
if (w && !w.closed) {
w.close();
}
}
}
</script>
It's necessary to call window.open() again on the window named "statusWindow".
If you do not, you will not have a reference (handle) to it, and will not be
able to close it. I tested it in IE6SP1, Netscape 4.78, Firefox 0.9.2 and
Opera 7.53 and it allowed me to open and close the window without holding a
reference to it.
