Passing a variable to two fields - Webmaster Forums - Webmaster forum for HTML, PHP, ASP, CSS and more

Hi all,

Quick question, probably very easy but I don't know...

I have a very simple forum:

Code:

<FORM action=http://WEBLINK method=get>
Field1 <INPUT name=field1> 
<BR><INPUT type=submit value=Search> </FORM>

I want to pass this through the forum as field1 and field2 without the user having to enter it twice. I'm guessing it is just some javascript? Would the submit button need to read the value, copy it to a hidden field2 variable and then submit the form? BTW, I cannot duplicate the value on the page I am submitting to.

Thanks in advance!

Anyone know if this is possible?

Why would you want to pass the same value twice on purpose?
To answer your question. Yes it's possible, copy value from one element to another with javascript.

document.getElementByID("element1").value=document .getElementByID("element2").value

make sure your elements have an ID.

You don't need javascript for that. Just create a hidden field on your form and store value there.

I think he's talking about submitting two values. Even if you have a hidden field you need to populate its value with something, and the only way of doing it on CLIENT side is with javascript.
