Store Locator Plus® was updated with a “pub/sub” model a few years ago. This feature is a managed interface for jQuery Callbacks that allows disparate Javascript functions to interact with each other. It works much like hooks and filters in WordPress, but solely within the JavaScript runtime space.
The basic premise is any JavaScript function can call a “publish” method that fires off a stack of callbacks.
slp_Filter('slp_map_ready').publish(cslmap);What is run by those callbacks is set by having a JavaScript module call a “subscribe” method.
slp_Filter( 'slp_map_ready' ).subscribe( this.initialize );
