Dynamic form element names in function

[dragonturtle]

Hi,

I have a form in page that looks something like this:

<form name=myForm>
<input type=text name=value1 onBlur=calculateForm(1)>
<input type=text name=result1>
<input type=text name=value2 onBlur=calculateForm(2)>
<input type=text name=result2>
<input type=text name=value3 onBlur=calculateForm(3)>
<input type=text name=result3>
</form>

The calculateForm() function needs to take the parameter and append it to the name of the field, but I can't figure out how to do it.

function calculateForm(num)
{
  var d = document.myForm;
  d.result+num.value = d.value+per.value;
}

Any help is appreciated. Thanks.

Woohoo! Figured it out! It worked like this:

function calculateForm(num)
{
  var d = document.myForm;
  d["result"+num].value = d["value"+num].value;
}
