Hidden input feild on condition

Copy linkTweet thisAlerts:
Oct 28.2006

Hi all,

I will start by stating that I do not know how to achieve what I need to do.

I have a form on the page with many feilds. One of the feilds is called “country” and another is called “VAT”.

What I need to do is if a user selects “United Kingdom” from the country list the “VAt” input feild shuld appear. This is how I see it happening:

<SCRIPT language=”JavaScript”>
function VAT() {
if(document.form1.country == ‘United Kingdom’)

“DISPLAY VAT FEILD”
{
if(document.form1.country == ‘EU Country’

and

if(!is_set(company_name))

{

“DISPLAY VAT FEILD”

else

“DO NOT SHOW VAT FEILD
++++++++++++++++++++++++++++++++++

I said I did not know what or how to do this, I am more PHP but I know I should learn JavaScript.

Can anyone point me in the correct direction and help.

Many thanks

Dereck

@konithomimoOct 28.2006 — Since PHP and Javascript are very similiar you already have most of it. To fix it change this:

if(document.form1.country == 'United Kingdom')


to

if(document.form1.country.value == 'United Kingdom')

and then to display the field:

document.getElementById('vat').style.display='block';

and to hide it:

document.getElementById('vat').style.display='none';

where 'vat' is replaced with the ID of the 'vat' field.

Success!
