javascript - Difference between dojo/on and dojo/aspect -


in dojo javascript library, dojo/on , dojo/aspect used functions listen events.

however don't see how differ 1 another. can explain when use on , when use aspect?

dojo/on used listening events. dojo/aspect used intercept calls javascript functions.

with aspect, can intercept function call , before function call, after, or both. events, being notified occurred.

technically, if target object not domnode, dojo/on ends calling aspect.after(...)

in <=1.6, there not distinction , dojo.connect used. functions used notify event occurred , there still remnants of in code base. example using on click event on dijit/button.
