Passing parameter to css :not selector

I have a function to hide all divs on the page except one div.

// hide all div exceept div1
function hideAllExcept()
{
  $('div:not(#div1)').slideUp(800);
}

or

// hide all div exceept 'thisdiv' 
function hideAllExcept()
{
  $('div:not("#div1")').slideUp(800);
}

The above works fine (difference is first function doesn't have "" around #div1). However, I would like to pass a parameter in开发者_开发知识库 the hideAllExcept function to dynamically specify which div to not hide. So I changed the function to:

// hide all div exceept 'thisdiv' 
function hideAllExcept(thisdiv)
{
  $('div:not(thisdiv)').slideUp(800);
}

if i call the function using: hideAllExcept('#div1') or hideAllExcept("#div1") it doesn't work. It seems that $('div:not(thisdiv)') still selects all divs, it doesn't exclude thisdiv.

Any ideas? Many thanks

Change it to:

function hideAllExcept(thisdiv) {
  $('div:not('+thisdiv+')').slideUp(800);
}

$('div').not(thisdiv).slideUp(800);

var divid='div:not('+thisdiv+')';
$(divid).slideUp(800);
