for loop that should run many times only runs twice?

[questor]

For some reason the following code only output 2 lines of <tr>blahblah</tr>, even if it should run many times. Why?


if (pickedFunction == 2)
{
viewerOutput = '<table>';
<?
mysql_select_db("staff");
$sql14 = "SELECT dt FROM employment";
$sql14 = mysql_query($sql14);
while ($row = mysql_fetch_array($sql14, MYSQL_ASSOC))
{
foreach ($row as $dt)
{
echo "if (selected == ".$dt.") { for (i=1;i<magic".$dt.".length;i++) { var id = magic".$dt."[i]; component = '<tr bgcolor=\"#F0F0F0\" style=\"cursor:hand\" onmouseover=\"javascript:this.style.backgroundColor=\'#dddddd\';\" onmouseout=\"javascript:this.style.backgroundColor=\'#F0F0F0\'\" onclick=\"document.location=\'http://scwebapps/magic/detail.php?detailid=' + id + '\'\"><td align=\"center\">' + magicScore[id] + '</td></tr>'; viewerOutput += component; } }";
}
}
?>
viewerOutput += '</table>';
}

You should post the generated output of PHP. View-Source the page and post that javascript part here.

That is one small chunk of code altered slightly and repeated until it's an enormous chunk of code.

A slight modification would allow it to run as a single small chunk of code:


if (pickedFunction == 2)
{
viewerOutput = '<table>';
var mymagic = document['magic' + selected]
for (i=1;i<mymagic.length;i++)
{
var id = mymagic[i];
component = '<tr bgcolor="#F0F0F0" style="cursor:hand"
onmouseover="javascript:this.style.backgroundColor=\'#dddddd\';"
onmouseout="javascript:this.style.backgroundColor=\'#F0F0F0\'"
onclick="document.location=\'http://scwebapps/magic/detail.php?detailid=' + id + '\'">
<td align="center">' + magicScore[id] + '</td></tr>'; viewerOutput += component;
}
viewerOutput += '</table>';
}



I'll leave it up to you to get it back to the original PHP but this would dramatically reduce the size of the generated page and thus free up network loading.

Shouldn't it be window and not document?

window['magic' + selected]

[Roy Sinclair]

You're right it should be window, document will probably only work right for users of IE.

[questor]

Actually, only IE users will be using it. Thank you for finding an optimization. Turns out that /sigh/ a size of a frame set before hand was making it APPEAR to only run twice. It was working correctly the entire time. /slaps forehead/

How about that, huh?

[Roy Sinclair]

As long as the problem is solved :thumbsup: .

The optimization should help a lot too.

[glenngv]

You're right it should be window, document will probably only work right for users of IE.
It works in Firefox too, and I assume for other browsers also. But window.varName is different from document.varName. Try this demo:

<script type="text/javascript">
var blah = "bar";
document.blah = "foo";
alert(window.blah); //alerts "bar"
alert(document.blah); //alerts "foo"
</script>
