I work much better with examples, I hope this helps.
The first set of parenthesis is the selector, consider this hidden
field:
<input type="hidden" id="thisHidden" value="12.21">
If you'd like to fetch the "12.21" out of this hidden field, think of
a CSS selector (where ID = # and CLASS = .):
var thisVal = $("#thisHidden").val();
then if you do an 'alert' on this val:
alert(thisVal);
12.21 would be alerted.
jQuery rocks, have fun and keep after it, you'll be glad you did.
