Hi all,
i just use ccs for a week and i'm a newbie in programming that's why i choose ccs. i need help how can i auto calculate 2 text box value and store the result in another text box.
text box 3 = text box 1 * text box 2
how can i do that in ccs code? i found a javascript code to do auto calculate but i don't kno ho to apply it in ccs.
<script type="text/javascript" language="javascript">
function autocalc(oText)
{
if (isNaN(oText.value)) //filter input
{
alert('Numbers only!');
oText.value = '';
}
var field, val, oForm = oText.form, total = a = 0;
for (a; a < arguments.length; ++a) //loop through text elements
{
field = arguments[a];
val = parseFloat(field.value); //get value
if (!isNaN(val)) //number?
{
total += val; //accumulate
}
}
oForm.total.value = total; //out
}
</script>
</head>
<body onload="document.forms[0].reset()">
<form style="width:260px;margin:100px auto;border:2px black dashed;">
<table cellspacing="8">
<tr>
<!-- pass field reference ('this') and other field references -->
<td>value 1___<input name="t1" type="text" onkeyup="return autocalc(this,t2,t3)" tabindex="1"></td>
<td rowspan="3"><strong>total_____</strong><input name="total" type="text" readonly="readonly" value="0" tabindex="-1"></td>
</tr><tr>
<td>value 2___<input name="t2" type="text" onkeyup="return autocalc(this,t1,t3)" tabindex="2"></td>
</tr><tr>
<td>value 3___<input name="t3" type="text" onkeyup="return autocalc(this,t1,t2)" tabindex="3"></td>
</tr>
</table>
</form>

I assume it is on a record form...
so you put this code on the On Validate Event.
$tb1 = $Component->TextBox1->GetValue();
$tb2 = $Component->TextBox2->GetValue();
$calculation = ($tb1 + $tb2);
$Component->TextBox3->SetValue($calculation);
YOu can replace TextBox1, 2 and 3 with the names of your textboxes of course..in my example.. TextBox3 would be a Hidden field.

Hi ckroon,
can i use your method to make a calculation in a grid? i mean not in a record grid. i need to divide 2 calculation results and divide with 100.
from your example
//calculation 1
$tb1 = $Component->TextBox1->GetValue();
$tb2 = $Component->TextBox2->GetValue();
$calculation = ($tb1 + $tb2);
$Component->TextBox3->SetValue($calculation);
//calculation 2
$tb3 = $Component->TextBox3->GetValue();
$tb4 = $Component->TextBox4->GetValue();
$calculation2 = ($tb3 + $tb4);
$Component->TextBox5->SetValue($calculation2);
i try this in the record grid but give an error..
$test1=$component->textbox3->GetValue();
$test2=$component->textbox5->GetValue();
$calc=($test1/$test2)*100;
$component->result_calc->SetValue($calc);
is it possible to use the method in a grid view?
Thank in advance

i try this too but the same error happen
$b_qty = $Component->rab_qty->GetValue();
$b_price = $Component->rab_price->GetValue();
$r_qty = $Component->real_qty->GetValue();
$r_price = $Component->real_price->GetValue();
$dif_percent= (($r_qty * $r_price) / ($b_qty * $b_price))*100;
$component->dif_percent->SetValue($dif_percent);

check to make sure that
$component->dif_percent->SetValue($dif_percent);
is pointing to your hidden field.. and that it is named properly.

hi inoycavalera,
Good Day!
not sure if you mentioned anything about the event in which you placed your codes, try putting your codes in the beforeshowrow event of the grid. hope that helps... all the best!
Pal,
Benjohn
