<img src> attr('src') returns empty string prop('src') returns the URL of the page

Corrected for the incorrect selector syntax and a bare-property output added:

It seems to be reflecting the src attribute to the src property correctly using the process described in ​http://www.w3.org/TR/html5/infrastructure.html#reflect

What value were you expecting for .prop(), and why?

I was writing a little routine to reload images in the event they fail to load, by setting img src back to itself.

I guess I was expecting prop('src') to return null.

Definitely check those expectations against the standard. Most of the time reflected properties return an empty string rather than a null or undefined when the attribute is missing but we're not going to do something counter to the spec.
