jquery-pubsub

Implementation of pubsub that allows for hierarchical categorical publish and subscribe categories are . separated. all subscriptions to base or base.item or base.item.action would get messages published to base.item.action but subscriptions to base.item.action would not get messages published to base.item

The first parameter sent to listeners is the full topic, so listeners can do their own filtering if they subscribe to a more general topic You can (un)subscribe to multiple topics by separating them by spaces, this does limit it to events with no spaces in their names though You can publish to multiple topics the same way, just remember that the system automatically publishes to the less specific topics

jQuery.pubsub.subscribe('c49.filter.change', function(topic, msg){
    //Do something on filter change
});

jQuery.pubsub.publish('c49.filter.change', {
    "action":"add",
    "filter":{"value":1,"label":"The price filter"}
});

jQuery.pubsub.subscribe('c49', function(topic, msg){
    //c49 Super Listener to log all messages
    console.log(topic, ': ', msg);
});

jQuery.pubsub.subscribe('*', function(topic, msg){
    //Global Super Listener to log all messages regardless of topic
    console.log(topic, ': ', msg);
});
