Howto point to a textbox?

[Richard Salin]

Hi
I just wondered how I can refer to the following two
textboxes in this form:

<FORM action="FormWrite.php" method="post" name="submitForm">
<INPUT NAME="inputValues[etunimi]" SIZE=40>
<INPUT NAME="inputValues[sukunimi]" SIZE=40>
<INPUT TYPE="button" onclick="javacscript:sendForm();"
VALUE="Lähetä">
</FORM>


the reason the [] signs are in the name is to get all the textboxes values
in one variable
when using a php script.

- But how can I refer to it with javascript? For example; I tried

alert(document.submitForm.inputValues[etunimi].value);

....but it doesn't work. Can anyone tell me how this is done?
Thanks in advance!

Richard

No, that certainly wouldn't. The square bracket notation is used to access
properties. In addition to the relevant article in the Quick Answers
section of the FAQ, you might want to read this article in the FAQ notes:

Hope that helps,

The link was very informative, thanks for that, but I haven't figured out
how I could refer directly to the boxes.
I wouldn't want to change their names since the php
script is builded to support those names.
Is it possible to refer to the names with the square brackets? and if so
how?
Thanks again!

Yes.

var form = document.forms['submitForm'];
var etunimi = form.elements['inputValues[etunimi]'];
var sukunimi = form.elements['inputValues[sukunimi]'];

Good luck,
Mike
