JavaScript - Setting / Getting Cookies

Ive looked it up on google and yahoo but i just cant find good explanations on how to use cookies?

Hi,

Im a bit stuck on something, any help is greatly appreciated.

I want a user to input a name, age, gender, city into a form, this gets stored in some cookies and when they click submit they are taken to another page where their details are displayed in the webpage.


Thanks for the help.

Hi all, I need some help. I have a javascript thing on my site that changes the css layout from standard to alternate, and that works fine. Now I am wondering if it's possible for it to store a cookie, that when any of the pages on my site (this javascript thing is on every page) are re-loaded or the user navigates to a different page, it will keep the alternate stylesheet. Then, when it is changed back, the cookie gets deleted. Here's my code:

Header:
Code:

<link rel="stylesheet" href="<?php bloginfo('stylesheet_url'); ?>" type="text/css" media="screen" title="default" />
<link rel="alternate stylesheet" href="/wp-content/themes/new/darkside.css" type="text/css" media="screen" title="darkside" />
<script language="javascript" src="/wp-content/themes/new/darkside.js"></script>

Darkside.js
Code:

// *** TO BE CUSTOMISED ***

var style_cookie_name = "style" ;
var style_cookie_duration = 30 ;

// *** END OF CUSTOMISABLE SECTION ***

function switch_style ( css_title )
{
// You may use this script on your site free of charge provided
// you do not remote this notice or the URL below. Script from
// http://www.thesitewizard.com/javascripts/change-style-sheets.shtml
  var i, link_tag ;
  for (i = 0, link_tag = document.getElementsByTagName("link") ;
    i < link_tag.length ; i++ ) {
    if ((link_tag[i].rel.indexOf( "stylesheet" ) != -1) &&
      link_tag[i].title) {
      link_tag[i].disabled = true ;
      if (link_tag[i].title == css_title) {
        link_tag[i].disabled = false ;
      }
    }
    set_cookie( style_cookie_name, css_title,
      style_cookie_duration );
  }
}
function set_style_from_cookie()
{
  var css_title = get_cookie( style_cookie_name );
  if (css_title.length) {
    switch_style( css_title );
  }
}
function set_cookie ( cookie_name, cookie_value,
    lifespan_in_days, valid_domain )
{
    // http://www.thesitewizard.com/javascripts/cookies.shtml
    var domain_string = valid_domain ?
                       ("; domain=" + valid_domain) : '' ;
    document.cookie = cookie_name +
                       "=" + encodeURIComponent( cookie_value ) +
                       "; max-age=" + 60 * 60 *
                       24 * lifespan_in_days +
                       "; path=/" + domain_string ;
}
function get_cookie ( cookie_name )
{
    // http://www.thesitewizard.com/javascripts/cookies.shtml
    var cookie_string = document.cookie ;
    if (cookie_string.length != 0) {
        var cookie_value = cookie_string.match (
                        '(^|;)[\s]*' +
                        cookie_name +
                        '=([^;]*)' );
        return decodeURIComponent ( cookie_value[2] ) ;
    }
    return '' ;
}

EDIT:

Actually, this is what happens:

The user enters the konami code and a div shows/hides.

There you are given the option to turn off/on the alternate style.

Then I want the cookie to begin..

Hi is it possible to email cookies to my email address.
I have a order form and it saves all the information within a cookie and then goes to the payment page. I want to email the order details along with the payment detail to myself. Is this possible and how.

Below example of my cookie:

Code:

function nextForm() {
document.cookie = "prod1=" + encodeURIComponent(document.forms[0].prod1.value);
document.cookie = "prod2=" + encodeURIComponent(document.forms[0].prod2.value);
document.cookie = "prod3=" + encodeURIComponent(document.forms[0].prod3.value);

location.href="Payment.html";
}

I then have my payment cookie:
Code:

function paymentForm() {
	document.cookie = "FirstName=" + encodeURIComponent(document.forms[2].firstname.value) + ";secure=true";
	document.cookie = "LastName=" + encodeURIComponent(document.forms[2].lastname.value) + ";secure=true";
	document.cookie = "Email=" + encodeURIComponent(document.forms[2].email.value) + ";secure=true";
	document.cookie = "PhoneNumber=" + encodeURIComponent(document.forms[2].telephone.value) + ";secure=true";
	document.cookie = "Address=" + encodeURIComponent(document.forms[2].address1.value) + ";secure=true";
	document.cookie = "Address=" + encodeURIComponent(document.forms[2].address2.value) + ";secure=true";
	document.cookie = "City=" + encodeURIComponent(document.forms[2].city.value) + ";secure=true";
	document.cookie = "Province=" + encodeURIComponent(document.forms[2].province.value) + ";secure=true";
	document.cookie = "PostalCode=" + encodeURIComponent(document.forms[2].code.value) + ";secure=true";
	document.cookie = "AmountDue=" + encodeURIComponent(document.forms[2].totalDue.value) + ";secure=true";
	document.cookie = "CardName=" + encodeURIComponent(document.forms[2].cardName.value) + ";secure=true";
	document.cookie = "CardNumber=" + encodeURIComponent(document.forms[2].cardNumber.value) + ";secure=true";
	if (document.forms[2].correct.checked == true)
		document.cookie = "T&C Agreed = " + encodeURIComponent(true) + ";secure=true";
	top.location.href="thankyou.html";
}

and then my thankyou page from where it should be submitted to my email i am using a onload in the body but dont know what the code should look like.:
Code:

<body class="sale" onload="postCookie(); redirect(); return true">

<tr valign="middle"><td colspan="4" rowspan="10" align="center"><br /><hr />
<strong>Thank you for order! Your order will be processed within the next 48 hours.<br />
Your tracking number and postage details will be sent via email.<br />
You will now be taken back to the Home Page.<br />
Thanks for your support.</strong><br /><hr /><br />
<a href="http://www.sayorkies.co.za/home.html">Click here if your browser does not automatically redirect you.</a>

Hello,

I know there are dozens of threads on this topic but I can't figure out how to do what I want to do.

I have three variables I want to store in a cookie when a user leaves this page which is a college project: http://jimbolgs.agilityhoster.com/wo.../ClockUTC.html

They are (from the linked JS file): extraMins, geoLoc, UTCHours.

I would also like to retrieve them on return to the page.

Any help appreciated, Thanks.

Hi there Guys,

I'm looking to set a cookie that lasts 24 hours and has a specific name.
The function is to check how many times a page has been visited by individual people and display it at the bottom of a HTML page.

I have an existing script that holds the data for 6 months that i have found as below.

My question, Can any one help me change this to the required time?

I'm a Noob when it comes to java scripting but enthusiastic to learn.

Code:

<SCRIPT>


expireDate = new Date
expireDate.setMonth(expireDate.getMonth()+6)
jcount = eval(cookieVal("jaafarCounter"))
jcount++
document.cookie = "test jaafarCounter="+jcount+";expires=" + expireDate.toGMTString()

function cookieVal(cookieName) {
thisCookie = document.cookie.split("; ")
for (i=0; i<thisCookie.length; i++){
	if (cookieName == thisCookie[i].split("=")[0]){
		return thisCookie[i].split("=")[1]
	}
}
return 0
}

function page_counter(){
for (i=0;i<(3-jcount.toString().length);i++)
document.write('<span class="counter">0</span>')
for (y=0;y<(jcount.toString().length);y++)
document.write('<span class="counter">'+jcount.toString().charAt(y)+'</span>')
}

</SCRIPT>

I am hitting a brick wall, dont know what to do?

Hello everyone!

I am having really tough time learning JavaScript Cookies!

Can somebody explain me how to use them?

"Please do not provide any external links! It is a request!"

Any type of basic lesson/advice/suggestion will be quite helpful to me.

Thanks!

I dont know the best way to explain this in tech terms so I will do my best in laymen.

Hello here
I'm trying to make my fancybox on exit pop up run only once using cookies but it keeps showing every time i refresh or back the page. (I installed cookies plugin and fancybox plugin).
It seems like the cookie isn't getting value, like its null all the time.
This is my code maybe you can help me here. Thanks!
Code:

<script type="text/javascript">
	function PopIt() 
	{
		var COOKIE_NAME = 'cook';
        if($.cookie(COOKIE_NAME) != 'active') 
		{
           $.cookie(COOKIE_NAME, 'active', { expires: 7 });
				$("a#trigger").trigger('click');
				window.onbeforeunload = UnPopIt;
				return "Before you leave:\nPlease take a few seconds to answer 2 questions"; 	
		}
	}	
	function UnPopIt()  { /* nothing to return */ } 
 
	$(document).ready(function() {
		window.onbeforeunload = PopIt;
 
		$("a#trigger").fancybox({
			'hideOnContentClick': false,
			'showCloseButton': true
		});
 
		$("a[id!=trigger]").click(function(){ window.onbeforeunload = UnPopIt; });
	});

Hi all,

I've been trying to set, get and delete js cookies for a while now, although they seem to set (from what I can tell) I can't seem to do what else I need with them.

This is what I'm trying to do:

Function1 - setCookie (sets a cookie called 'saveAndExit' - that's it, no expiry date)

Function2 - useCookie (checks to see if a cookie called 'saveAndExit' exists and if it does alert("COOKIE WORKS") and then deletes the cookie

If it doesn't exist alert("cookie does not exists")

Could anyone assist with this? It's been driving me insane for days!

Thanks.

i am doing an edit operation in my web page by changing a image,
but when i am revisiting the page it is showing older image rather than new one.
So can any one say how to refresh the page without using any button like window.location.reload().
Is there any way to use math.random in url??

Hi, the cookies I am trying to read are values from a form that were stored. The problem I am having is that one value form the form, the value is 5000, was stored as a cookie but I cannot read it. When I display it, it returns: [object HTMLInputElement].

The code for storing the value is this:
Code:

document.cookie = "bankRoll=" + encodeURIComponent(money) + "; expires=" + expireDate.toUTCString();

, where money = 5000.

The code for reading the cookies is this:
Code:

var cookies = decodeURIComponent(document.cookie);
 var cookieNumber = new Array(10);
 cookieNumber = cookies.split("; ");   
	for(var i = 0; i < cookieNumber.length; ++i)
{
	var equalPos1 = cookieNumber[i].search("="); 
if (cookieNumber[i].substring(0, equalPos1) == "firstName") 
	firstName = cookieNumber[i].substring(equalPos1 + 1); 
if (cookieNumber[i].substring(0, equalPos1) == "lastName") 
	lastName = cookieNumber[i].substring(equalPos1 + 1); 
if (cookieNumber[i].substring(0, equalPos1) == "pCode") 
	pCode = cookieNumber[i].substring(equalPos1 + 1); 
if (cookieNumber[i].substring(0, equalPos1) == "bankRoll") 
	bankRoll = cookieNumber[i].substring(equalPos1 + 1); 
if (cookieNumber[i].substring(0, equalPos1) == "lastVisit") 
	lastVisit = cookieNumber[i].substring(equalPos1 + 1); 
	
}

The only one that does not display properly is the variable bankroll. All the others return the proper value.

I would like to know how to fix my code so that the value 5000 is displayed.
