Description

If I have a dijit.form.HorizontalSlider? or dijit.form.VerticalSlider? and try to use dojo.connect(dojo.byId('mySlider'), 'onchange', alertFunction), my alertFunction never gets called. However, if I use dojo.connect(dijit.byId('mySlider'), 'onChange', alertFunction), then alertFunction does get called with the string value of the slider.

I believe that both are supposed to work and that the conenct with dojo.byId will pass in the event object to the handler and the connect with dijit.byId will pass in the string value to the handler. I read this in the dojo book (http://dojotoolkit.org/book/dojo-book-0-9/part-3-programmatic-dijit-and-dojo/event-system/simple-connections-dojo-connect) and I observed this using dijit.form.ValidationTextBox?. That is why I think this is a bug with slider.

this is likely 'invalid' - dijit.byId / onChange is a synthetic event (actually, just a function) and it is not supported to mix and match DOM events with Widget "events". onChange is meant to normalize the "onchange" dom event, and only passes the changed value. Some widgets may _seem_ to support mixing of dom events and dijit events, but only as an artifact of the nature of event bubbling. dijit.byId('foo').domNode !== dojo.byId('foo'), though in some cases it does (but it doesn't count, because it isn't technically supported)
