variable part of a variable

[Markus Schdrunz]

Hi,

i have a site with many textareas which got numbered names (answer1,
answer2, answer3). beside each textarea is a link, calling the
javascript-function putText(). i give the number of the textarea with
the call: p.e. putText(1)

in the function putText(textare a) i want to change now
dokument.myform .answerX.value
the X behind answer should be the number of the textarea, given to the
function with the call

sorry, about my english ;-)

Try:

function putText( taIndex ) {
document.forms['form_name'].elements['answer' + taIndex].value
= 'Whatever should be assigned to the textarea';
}

where the argument, taIndex, is number of the textarea (that is, 1 in
'answer1', etc), and replacing the form name (form_name, above) and new
value as appropriate.

Hope that helps,
Mike
