javascript - Update a row in Parse.com -

what have when edit button clicked values in 2 input fields create new row , old row dropped.below code used want original row updated , not deleted. live example of how using code below works.

editbtn.onclick = function () {     alert("edit btn");     alert(name.value + " " + lname.value);       contact.save(null, {     success: function (contact) {           contact.set("firstname", name.value);         contact.set("lastname", lname.value);         contact.save();              object.destroy({                 success: function (myobject) {                  alert("destroy");                 location.reload();                },                 error: function (myobject, error) {                  alert("error: " + error.code + " " + error.message);                 }               });                                                  }           });          } 

just clarify want update rows not create new 1 while deleting old one.

edit: link above question asked in parse forums.

edit: more information added in link reply comment.

edit: added this code editing first name ("newfname") wont update last name ("newlname").

editbtn.onclick = function () {                      var query = new parse.query(contact);                     query.equalto("lastname", newlname.value);                     query.first({                         success: function (contact) {                             contact.save(null, {                                 success: function (contact) {                                      contact.set('firstname', newfname.value);                                     contact.set('lastname', newlname.value);                                      contact.save();                                     location.reload();                                 }                             });                         }                     });                 } 

where have query.equalto("lastname", newlname.value), tried put in objectid i.e. (query.equalto("objectid"); didn't work me.

any ideas?

i managed updating code.

editbtn.onclick = function () {     var query = new parse.query(contact);     query.equalto("objectid", object.id);     query.first({         success: function (contact) {             contact.save(null, {                 success: function (contact) {                     contact.set("firstname", newfname.value);                     contact.set("lastname", newlname.value);                     contact.save();                     location.reload();                 }             });         }     }); }
