Clear cookies with javascript -

-

i ask here. have update form , when submit need send 2 values main page. (they contains combobox index , table rowindex trigger them , show me selected item have choose before submit. otherwise selects first items) im using cookies , works well. problem cant clear cookies. after update loads previous values when document load.

i have following:

document.cookie="data1="+variable1+"; path=/"; document.cookie="data2="+variable2+"; path=/"; //they holds variables//

and when page loads data back:

$(document).ready(function() {  var x = document.cookie.split(';');  if ( x !== null) { var x1 = x[0].split('=')[1]; var x2 = x[1].split('=')[1]; };  //i need cookie clear function here next time page loads select first items again//

i tried none of them works:

1st:

 function clearlistcookies(){         var cookies = document.cookie.split(";");             (var = 0; < cookies.length; i++){                    var clear =  cookies[i].split("=");                 document.cookie = clear[0] + "=;expires=thu, 21 sep 1979 00:00:01 utc;";                                             }         }

2nd:

document.cookie = "data1=; expires=thu, 01 jan 1970 00:00:00 utc";  document.cookie = "data2=; expires=thu, 01 jan 1970 00:00:00 utc";

thanks in advance

you need specify path so:

document.cookie = "data1=; expires=thu, 01 jan 1970 00:00:00 utc; path=/";  document.cookie = "data2=; expires=thu, 01 jan 1970 00:00:00 utc; path=/";
