JS shorterhand conditional? [duplicate]

Question

I am using the following shorthand conditional in JS/jQuery:

var delay = $(this).data("delay") ? $(this).data("delay") : options.delay;

If the element has a data-delay attribute use that value, otherwise get the value from options.delay.

It seems excessive using $(this).data("delay") two times in the shorthand conditional. Is there a better way to do it?

Would var delay = $(this).data("delay") || options.delay; be a good solution? I am not sure if all browser supports it.
