[jQuery] Checking whether a jquery function exists
Hi,
I'm using the datepicker widget on a site, but there may be pages
where the script is not called in the head, where there's no
datepicker needed on the page. (To save download time and to reduce
execution time)
the $(document).ready function will include a
$('.invokeBoth').datepicker( ... );
but this will be called on every page on the site - even those where
the datepicker script isn't called within the head.
How do I check that datepicker is a function?
I was thinking
if(typeof datepicker=='function'){ ... }
Is this even an intelligent way of attacking the problem of only
downloading the function when it's needed?
