The way how jQuery does mixing properties with attributes is a very
clever thing. One simple API for multiple different things is a very
nice thing, but has its constraints.
An example:
jQuery returns the value-property on form-elements, instead of the
value-attribute. This is a really good thing, because
a) a lot of novice developers don´t know about the difference and are
expecting this behavior
b) more advanced developers know the difference, but want in general
to know the value-property of a form element
With other words the developer gets what he/she wants/expects here.
But if jQuery starts to make .attr('height') equal to .height(), the
behavior becomes very unexpected. Everybody knows that the height-
attribute can be simply "overridden" by using css. This is why a
developer would use height to get the height-dimension of an element
and if a developer wants to know what the height-attribute, he would
call attr('height').
If you change your API to this behavior you will
a) break existing code
a) do unexpected things
b) you don´t have a jQuery-method, wich returns the height-/width-
attribute anymore
To be clear:
I think, you did a great job mixing properties and attributes and if
you know start to take this a step further, I am also on your side,
but you have to make wisley decissions (and small steps) here.
If you can solve the discrepancy in event-binding with attr, Robert is
mentioing, it could be a nice feature, but please don´t do this with
height/width!
