ValueChange Class
+ + + + +Provides the implementation for the synthetic valuechange event. This class
+isn't meant to be used directly, but is public to make monkeypatching possible.
Usage:
+ +YUI().use('event-valuechange', function (Y) {
+ Y.one('#my-input').on('valuechange', function (e) {
+ Y.log('previous value: ' + e.prevVal);
+ Y.log('new value: ' + e.newVal);
+ });
+});
