You'll have to use a closure. Normally you would use a static variable. in Javascript it would look something like:

jQuery( document ).ready( function(){
    setInterval( myFunction, 3000 );
});

var myFunction = (function(){
    var count = 0;
    return function(){
         count++
         alert( "I have been called " + count + " times");
    }
})();
