I found the solution, incase someone needs it later

here it is:

var GameScore = Parse.Object.extend("Driver");
var query = new Parse.Query(GameScore);
query.equalTo("DriverID", "9");
query.first({
  success: function(object) {

     object.set("DName", "aaaa");
    object.save();


  },
  error: function(error) {
    alert("Error: " + error.code + " " + error.message);
  }
});
