And I just realized I should make it possible to stop the repeating 
function later on.

Code:
jQuery.fn.every = function(interval,fn) {
    return this.each(function() {
        var self = this;
        this.$every = window.setInterval(function() { fn.call(self) 
},interval);
    });
};

Example:
// Display the current time updated every 500 ms
$("p.display").every(500,function() {
    $(this).html(new Date());
});

//... some point later in the code execution
$("p.display").each(function() {
    window.clearInterval(this.$every);
    this.$every = null;
});
