[jQuery] JQuery "exists" - anything in core or a plugin that does this?

[James]

Hi,

I can't seem to find anything that does the following:

$("img").exists(function(matches) {
 /* do something with matches */
});

the difference between "exists" and "each" being it is only run once
and supplies all the matches as an argument.

The long-hand way of doing this is something along these lines:

var matches = $("img");
if (matches.length) {
  /* do something */
}

Before I write myself a quick plugin, is there an obvious alternative
I've missed???

Regards,

James
