javascript - jQuery: remove a cookie when closing the browser (session cookie) -

-

it sounds simple , think should simple, somehow don't work...

i want set cookie using javascript , cookie should removed when user quits browser. setting cookie , getting value not problem. when quit browser , reopen it, cookie still there (firefox).

i use jquery , cookie-plugin.

here test code:

$(document).ready(function(){ $('#output').append( '<li>initialize...</li>' );  var $cookieval = $.cookie('testcookie');  $('#output').append( '<li>check cookie...</li>' );  if(!$cookieval) {     $('#output').append( '<li>set cookie...</li>' );     $.cookie('testcookie', 'eat cookies', { path: '/' });     //console.log( $.cookie() ); } else {     $('#output').append( '<li>cookie set...</li>' );     $('#output').append( '<li>cookie value: '+$.cookie('testcookie')+'</li>' ); } });

please find working example @ jsfiddle.

i beginning wonder if testing method might problem here. so, going write in specific way.

actual answer: browser setting

in firefox, options>general>when firefox starts>"show windows , tabs last time" going preserve previous session. change setting see indeed working supposed to. firefox prolonging session. further information, see "bug": http://bugzilla.mozilla.org/show_bug.cgi?id=530594

there similar settings in browsers behave same way.

original answer:

i created fiddle, http://jsfiddle.net/8ahg2/ uses document.cookie rather jquery cookie plugin. here how test this. (source below)

  1. copy following url clipboard: http://fiddle.jshell.net/8ahg2/show/
  2. completely close browser of choice - should browser independent.
  3. open browser, paste url. first time should say: check cookie... set cookie...
  4. refresh page, notice should value of cookie ("test")
  5. close browser completely again.
  6. navigate url should still in clipboard. *do not refresh page on first view, should again 'check cookie... set cookie...'

js

$(document).ready(function () {     $('#output').append('<li>initialize...</li>');     //this regex gets "name" cookie out of string of cookies this: "name=test;var2=hello;var3=world"     var cookieval = document.cookie.replace(/(?:(?:^|.*;\s*)name\s*\=\s*([^;]*).*$)|^.*$/, "$1");      $('#output').append('<li>check cookie...</li>');      if (!cookieval) {         $('#output').append('<li>set cookie...</li>');         document.cookie = "name=test";     } else {         $('#output').append('<li>cookie set...</li>');         $('#output').append('<li>cookie value: ' + cookieval + '</li>');     } });
