[wp-hackers] Reacting to options (theme options) in Javascript

[Eric Mann]

I try to keep my PHP and JS as separate as possible.  When there needs to be any
integration, I set up a PHP function that echos the JS options I need access to
and hook it to wp_head.
 
So something like:
 
function returnJS() {
echo '<script type="text/javascript>';
echo "var myWordPressOptions = { 'option1' : 'value', 'option2' : 'value' };";
echo '</script>';
}
add_action('wp_head', 'returnJS');
 
Then you have access to all of your server-side WordPress goodness and can parse
the options as necessary before pushing them to the browser.  One of the options
you set can be a flag to your JS to activate your jQuery code ... or it could
even be a singleton function to do the same thing, it's up to you.
 
But this keeps your PHP files almost JS-free, and you can still enqueue your JS
libraries as usual.
