In jQuery, the class and ID selectors are the same as in CSS. If you want to select elements with a certain class, use a dot ( . ) and the class name. If you want to select elements with a certain ID, use the hash symbol ( # ) and the ID name.
In jQuery, the $ sign is just an alias to jQuery() , then an alias for a function. This page reports: Basic syntax is: $(selector).action() A dollar sign to define jQuery.
These are CSS selectors. The hash symbol # means that the element is an ID. So #row would match <div id="row"> . Alternatively, the dot symbol . means the element is a CSS class.
$('loc') is an element selector, looking for <loc> elements.
$('#loc') is an #id selector, looking for id="loc" elements.
Think CSS when looking at almost all jQuery selectors, they're very close if not identical in most cases.
