Yes!

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

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

There you go!

Yes!

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

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

Yes!

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

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

Improved function: `this` inside a `.fn` function points to a jQuery object. Don't wrap it again.
