[jQuery] Re: JQuery variables
The use of jQuery's $("#createNewAccount"). is cross-browser so you
shouldn't worry about IE.

Thanks for this response.
Unfortunately, I am left with the problem that Internet Explorer
doesn't seem to like the syntax $("#createNewAccount").
It works fine in firefox - any suggestions please?

[jQuery] Re: JQuery variables
#createNewAccount does not stand for a variable but for an ID attribute. To
check if the element exist you can check if it contains a value, if it does
by default or check if it contains any HTML inside the tags.

Hi there.
Best (or fastest) way to find out if something is in the DOM is to
check:
if ( $("#createNewAccount").length )
If .length is greater than 0 it will exist.
So your script can read:
$(document).ready(function() {
if ( $('#createNewAccount:checked').length || !$
('#createNewAccount').length ){
$('div.showHideAccountDetails').show();
}else{
jQuery('div.showHideAccountDetails').hide();
}
});
Ie, if it finds ( '#createNewAccount' that is checked ) OR ( it can't
find any '#createNewAccount' ) { show the div } otherwise { hide it }
Hope this helps!
