javascript functions

I have a form which is organized with a table, each row of the table has several form elements (at least 3 text fields each)

<form>
<tr>
<input type=text name="q1">
<input type=text name="q1_value">
<input type=text name="q1_total">
</tr>
<tr>
<input type=text name="q2">
<input type=text name="q2_value">
<select option ... name="q2_dazy">
<input type=text name="q2_total">
</tr>

...
<tr>
<input type=text name="q30">
<input type=text name="q30_value">
<select size=1 ... name="q30_dazy">
<select size=1 ... name="q30_lazy">
<input type=text name="q30_total">

</tr>...
<form>

Now I'm writing a javascript function, that'll fill in *_total based on *_value and a constant. i.e. q3_total = q3_value * 50;

My problem is that my way is really long, I have a lot of if statements to do it. Is there a better way?

my way:
function(name)
if (name == q1)
q1_total = q1_value * 50;
...
if (name == q30)
q30_total = q30_value * 50;

hi, underwarez

I think you should do it like this

function getTotal(name)
{
eval("document.mainForm." + name + "_total.value = document.mainForm." + name + "_value.value * 50");
}


and html code for proper working

<form name="mainForm">
<tr>
<input type=text name="q1">
<input type=text name="q1_value">
<input type ....
