I’m currently working with this awesome article by Otto: http://ottopress.com/2012/how-to-leverage-the-theme-customizer-in-your-own-themes/
For my question, I have two separately registered settings, and I’d like to see if I can get them to work together within my JS.

With both settings I can use jQuery bind to do alter things on site in real-time when each setting is changed, as the article explains. However, what I’m curious about is if when I’m working on one option, can I grab the current value from another option?
Hopefully, this screenshot will illustrate what I mean.

Note: In this example, I could probably come up with some workaround to get the currently set font-size with jQuery to determine the current value, but I’m more asking just as a general example if this is possible.
Thanks in advance!
What you could do is the following :
// ----------------------------------------------------------
// Primary Typograpy
// ----------------------------------------------------------
var current;
/* Primary Typography - Size */
wp.customize('typography_primary_size', function( value ) {
current.size = value;
value.bind(function(size) {
$('h1, h2, h2, h4, h5, h6').css('font-size', size);
});
});
/* Primary Typography - Face */
wp.customize('typography_primary_face', function( value ) {
current.face = value;
value.bind(function(face) {
if(current.size.get() == 'whatever'){
current.size.set('othervalue');
} else {
}
});
});
Sorry Otto, it’s perhaps a little bit hacky, but it works. The bonus is that you can also trigger the change callback using the set
method : current.size.set('othervalue')
will trigger your custom css change for h1 to h6 headers.
