Select elements by attribute

I have a collection of checkboxes with generated ids and some of them have an extra attribute. Is it possible to use JQuery to check if an element has a specific attribute? For example, can I verify if the following element has the attribute "myattr"? The value of the attribute can vary.

<input type="checkbox" id="A" myattr="val_attr">A</input>

For example how can I get a collection of all checkboxes that have this attribute without checking one by one? Is this possible?

A couple ideas were tossed around using "typeof", jQuery ".is" and ".filter" so I thought I would post up a quick perf compare of them. The typeof appears to be the best choice for this. While the others will work, there appears to be a clear performance difference when invoking the jq library for this effort.
