javascript - Removing Cookie value from browser -

i know has been asked many times, , ive tried using accepted answers. sadly none of seems work me in browser(mozilla v18.0.2).

i using backbone website , im using cookies handle user login sessions.

the following unsuccessful ones :

code 1

var cookie_date = new date ( );  // cookie_date.settime ( cookie_date.gettime() - 1 ); // 1 second before now. // empty cookie's value , set expiry date time in past. document.cookie = "uid=;expires=" + cookie_date.togmtstring(); document.cookie = "username=;expires=" + cookie_date.togmtstring(); 

code 2

var nameeq = name + "=";     var ca = document.cookie.split(';');     for(var i=0;i < ca.length;i++) {         var c = ca[i];         while (c.charat(0)==' ') c = c.substring(1,c.length);         if (c.indexof(nameeq) == 0){             uid = c.substring(nameeq.length,c.length);             return uid;         }  }; 

any working solution removing browser cookies??

thanks

simple answer

you can't.

long answer

you can overwrite cookie , give expiration time in past.

browsers discard @ point after expiration. until need check yourself, if has been “deleted”, e. g. special value or comparing expiration date current time.
