Please Wait, Calculating...

[Tree]

I have a page where a lot of charts and graphs are calculated. It can sometimes take 30 seconds or so for the calculations to finish and the charts to be displayed. How can I make it so it displays a message while the charts are calculating. Then when they're done, display them.

I have this code that Jim_ gave me:

echo "<div id=\"hidelater\"><b><img src='pages/style/loadingcircle.gif'>  Please Wait, Calculating Chart Output. </b></div>
<script>
function tensecs() { document.getElementById(\"hidelater\").innerHTML = '<b><img src=\"pages/style/loadingcircle.gif\">  This can take quite a long time if more than four ads are selected. Please be patient.</b>'; }
window.setTimeout('tensecs()',10000);</script>"; 
ob_flush(); flush();

// Over 300 lines of chart calculations

echo "<script>document.getElementById(\"hidelater\").style.display = 'none';</script>";

But the charts still display as they're loaded, and when they finish, the little message doesn't go away.

Any help would be appreciated

If the problem is that the charts are showing up before they are done, don't echo them.

Do something like (where you have // Over 300 lines of chart calculations):

<?php

$output = '';

// The 300 lines of chart calculations
$output .= 'The stuff you echoed before, but are now adding to this variable';

echo $output;

?>

This way, it only echo's one time so nothing will show up until you echo it.

It's showing one chart, then the next one finishes calculating and it pops up, and it all looks very... not good.

Thanks for the idea though. Think I'll try it.

But I also get this error

Thanks Dan, that worked beautifully
