Does jQuery actually use camelcaps to reference multiword css fields?

Question

In jQuery, are multiword css fields condensed to camelCaps? For instance.

$("#item").css("marginBottom"); 

not

$("#item").css("margin-bottom"); 

On my machine running Firefox 3.6.6 with jQuery JavaScript Library v1.4.2, the answer seems to be no. doing $("#item").css("marginBottom"); gives me a warning about invalid css field and that the declaration was dropped.

Answer 1

Actually I'm wrong - it seems internally it camelCases it. Here's a snippet of code that grabs the margin bottom ( tested in Fx 3.6 ):

el = document.body;
$('el').css('margin-bottom', '20px')
computed = document.defaultView.getComputedStyle( el, null )

computed['marginBottom'] // 0px

Update: Here's the camelcasing then lowercasing code from jQuery:

x = 'marginBottom'.replace( /([A-Z])/g, '-$1').toLowerCase()
