hide field on click of a button

[j-iN-uK]

Hi,

I want to hide a select box on click of the CLose Button.

if(isset($_POST['Close'])){

echo 'Test';

$sJavaScript = "function HideFields()

document.f1.LstSchoolName.style.visibility = 'hidden'";

}

This routine does get executed cos I the echo statemnt is shown except my listbox is not hiding, what am I doning wrong.

2 questions.

1. Are you printing the javascript code to your page, and calling the function?

2. Is your javascript code within <script> tags. You could try something like:

if(isset($_POST['Close'])){

$javascript = '
function hide_field(){

document.f1.LstSchoolName.style.visibility = "hidden";

}

hide_field();
';

echo 'Test';

echo '<script type="text/javascript">';
echo $javascript;
echo '</script>';

} 

The code could be compacted slightly more but this may give you a better idea.

You could also consider having php check if $_POST['close'] is set, and if it is just dont put the field in the page the first place, or making it a hidden field.

Hope this helps

You may also want to consider the use of DOM and Javascript entirely. Or even using CSS with "visibility: hidden".

Good luck,
