Is there an “exists” function for jQuery?

How can I check the existence of an element in jQuery?
The current code that I have is this:
if ($(selector).length>0) {
    // Do something
}
Is there is a more elegant way to approach this? Perhaps a plugin or a function?


Answer:

Yes!
jQuery.fn.exists = function(){ return this.length > 0; }

if ($(selector).exists()) {
    // Do something
}
