Hi there.
I have this Function: -
-
//Funzione Calcola
-
-
function calcola(frmObj, id)
-
-
{
-
-
-
//Somma Totale Imponibile
-
-
var somma_totale_imponibile = 0;
-
var nelementi = ["Totale_imponibile_" + id].length ;
-
-
for ( var n = 0; n <= nelementi; n++ )
-
-
{
-
n = parseFloat(frmObj["Totale_imponibile_" + id].value);
-
somma_totale_imponibile += ((isNaN(parseFloat(n)))?0:parseFloat(n));
-
alert(n)
-
}
-
-
alert("Totale_imponibile_" + id)
-
alert(somma_totale_imponibile)
-
-
frmObj.somma_totale_imponibile.value = somma_totale_imponibile.toFixed(2);
-
-
-
//chiusura funzione calcola
-
}
-
-
I require this datum:
Totale_imponibile_1 = 3
Totale_imponibile_2 = 50
Totale_imponibile_3 = 2
somma_totale_imponibile = 55
It doesn't work.
Can anyone help?
Thanks, regards

hi ...
welcome to TSDN ...
i think that doesn't work the way you intended. please show your html relating to this problem too ... because i assume nelementi should be a number of textboxes contained by your form?
kind regards
hi
well,I think there's a logical error in your code,but I can see what you want to do.so I write a code for you.I hope it's you want.

You're still starting at 0 in your loop. The first number should be 1.
Thanks, but not work: - <script language="javascript">

nelementi is not set correctly. Set that using the number of rows in the table or just use 9 (if its going to remain fixed).
In the for loop, use another variable name besides "n". You've already used it for indexing. Replace "id" with "n", so that you're not just accessing the same text box each time.
Nothing... no work: -

You've not made the changes.
On line 25, you're setting nelementi.
On lines 30-31, you will also need to make changes as I described earlier.

What I do not understand ?
Thanks
Try using 9 instead of nelementi, so that you can at least test that it's working.
In your latest code, on line 5, you don't need to parseFloat it again because that has already been done on the previous line.

Not working.

Not working.
Sorry.
OK, try this: -
for ( var n = 1; n <= 9; n++ )
-
{
-
x = parseFloat(frmObj["Totale_imponibile_" + n].value);
-
somma_totale_imponibile += ((isNaN(x))?0:x);
-
}
Ok this work thanks; but nelementi it is not always fixed 9.
It is a variable in the code...

Yes, I know that, but at least one problem is fixed.
To make nelementi variable, use the table's rows[] array: - var nelementi = document.getElementById("tableid").rows.length-2;
Sorry, but not working... -
var somma_totale_imponibile = 0;
-
//var nelementi = ["Totale_imponibile_" + id].length ;
-
var nelementi = document.getElementById("Totale_imponibile_").rows.length-2;
-
-
for ( var n = 1; n <= nelementi; n++ )
-
-
{
-
x = parseFloat(frmObj["Totale_imponibile_" + n].value);
-
somma_totale_imponibile += ((isNaN(x))?0:x);
-
}
-
-
alert("Totale_imponibile_" + id)
-
alert(somma_totale_imponibile)
-
-
frmObj.somma_totale_imponibile.value = somma_totale_imponibile.toFixed(2);

You're using the wrong id. The table id according to the source code is "table3".
Yes, this working !!!!!
You magician !!!
many thanks
