New Post: How to trigger a call to another function when a user fills the PeoplePicker

Marc asked to move the question out here so here it is:

How would you go about running “$().SPServices.SPFindPeoplePicker” whenever a user finishes selecting a user?

Is it as simple as:

$(document).ready(function() {

var supervisor = $().SPFindPeoplePicker({
  peoplePickerDisplayName: "Requesting Supervisor"
}); 
supervisor.onblur="Checksupervisor()";

});
function Checksupervisor(){

  var supervisor = $().SPFindPeoplePicker({ peoplePickerDisplayName: "Requesting Supervisor"}); 
  var current = supervisor.currentValue;
  alert(current);     

}


Thanks in advance.
