jQuery - convert .live() to .on()

Question

How do I go about combining this old jQuery code into the v1.7 .on()?

v1.3 .live():

    $(\'#results tbody tr\').live({
            


        

Answer 1

You can pass an event-map as the first parameter:

$('#results tbody').on({
    'mouseenter' : function () {
        $(this).find('.popup').show();
     },
    'mouseleave' : function () {
        $(this).find('.popup').hide();
    }
}, 'tr');

jQuery documentation:

.on( events-map [, selector] [, data] ),
events-map A map in which the string keys represent one or more space-separated event types and optional namespaces, and the values represent a handler function to be called for the event(s).
