How to replace "live" with "on" in jQuery 1.7+

The functions bind and live are being deprecated in jQuery 1.7+ in favor of on, but it’s not very clear how their differences reflect on it. As you might know, bind attaches event handlers on DOM elements existing at the time of running the instructions, while live also attaches these handlers to DOM elements added in the future. So how does it work with on?

$(".myClass").on("click", function(){...});

This way jQuery will attach the handler only to DOM elements with the class `myClass` that already exist in the DOM tree.

$(".myClass1").on("click", ".myClass2", function(){...});

This way jQuery will attach the handler to all DOM elements with class myClass2 that are descendants of DOM elements with class myClass1 even if they are added in the future.
