jquery - Ajax call to servlet making additional call to servlet -

i have ajax call servlet jquery:

function updatemapping() {         $.ajax({             type : "post",             url : "/tool/updatemap",             data : "maparray=" + maparrayvar+ "&submit=update",             datatype : "html",             success : function(data) {                 $(document).ajaxstop(function() {                     location.reload(true);                 });              }         });      } 

this call making no problem , after updating while reloading page again calling servlet "submit=save" attribute.

<span> <input type="submit" name="submit" class="buttonabc" value="save" /> 

so data getting save twice

on button pass event:

<input type="submit" name="submit" class="button60" value="update"   onclick="updatezonecirclemapping(event)" />  

in javascript prevent default action:

function updatemapping(e) {         e.preventdefault(); //prevents form submitting         $.ajax({             type : "post",             url : "/tool/updatemap",             data : "maparray=" + maparrayvar+ "&submit=update",             datatype : "html",             success : function(data) {                 $(document).ajaxstop(function() {                     location.reload(true);                 });              }         });  }
