When I'm adding a div to body, it's returning the body as the object and then whenever I use that - it's obviously using body. Bad.
Code:-
var holdyDiv = $('body').append('div');
$(holdyDiv).attr('id', 'holdy');
The 'id' of holdy is now being added to body... eh? What am I doing wrong.
jQuery methods returns the set they were applied on.
Use .appendTo:
var $div = $('<div />').appendTo('body');
$div.attr('id', 'holdy');
