Here is a tiny javascript that calculates the sum of every column in a
table, even if the columns mix links, letters and numbers. Credit goes
to 4umi.com/web/javascript/tablesum.php
Caveats: All table cells must have at least one whitespace.
Put this in a code.embed.somename file, add <embed somename> in your
template.last and put [t id=sumtable] in your template.first
<input type='submit' onclick='sumup(this)' name='submit'
value='Summe' /><p /><code>
<script language="javascript" type="text/javascript">
function sumup( o ) {
var t = [], cell,
row = document.getElementById( 'sumtable' ).rows,
i = row.length - 1,
lastrow = row[i];
while(i--) {
cell = row[i].cells; j = cell.length;
while(j--) {
if( !t[j] ) { t[j] = 0; }
t[j] += parseFloat( cell[j].firstChild.nodeValue ) || 0;
}
}
j = t.length; while(j--) {
if( lastrow.cells[j] ) { lastrow.cells[j].firstChild.nodeValue =
t[j]; }
}
o.disabled = true;
}
</script>
