JavaScript - Javascript Cookie Troubles
Hey guys,
Here is my question: Is it possible to extract a cookie inside a textarea? For example, I am building a very basic shopping cart in Javascript, with "Add to Cart" buttons listed for each item. As the "Add to Cart" button is pressed, a cookie is created. There is a link in which you can click with "Review Order", which consists of a textarea that displays the items that you have 'purchased'. I am trying to get the value of the cookie to be extracted into this textarea, however I am not sure if this is possible. Thanks Similar TutorialsHello everyone, I'm in a bit of a pickle. Here are all the details and I hope someone will be able to help me out... I have a CD; the way this CD installs is...when inserted, the CD runs a file Login.html...on this page there are 3 fields, login, password, and language (depending on which language you click on, that's the language that it automatically changes the Login and Password text to. The username and password need to be an account that is on a server that the login.html connects to. Once you log in, the system automatically bring you to the next page which is also located on the CD which is Install.html...now on this page, there are 4 fields. Destination of where I want to install, Language drop down, but here's the tricky part...the two other fields are Currency and Sales Origination. These two fields get auto populated depending on the language we selected on the first page, Login.html. but the trick is that if I bypass the Login.html file and point my browser directly to the Install.html file, the Currency and Sales Origination fields will be blank and I will not be able to install the application. Keep in mind, this is not an exe or MSI installation, it's a batch file that's on the CD and it performs several tasks such as moving files, extracting files, placing things in scheduled tasks, and a few other things. So what I need to do is figure out a way, hopefully with your guys help, is how to bypass the Login.html altogether so that I can run Install.html without needing anything from the Login.html. So I need to, I'm guessing, edit the Install.html file so that it already has Currency and Sales Origination pre-populated. Because if I go to Install.html directly and leave those two fields blank, the batch file that runs to install everything, it says there is no Currency file that is selected. Because the way it's created is it selects a certain .zip file from the CD and extracts it depending/according to the Currency and Sales Originations...which that depends all on the Language that was selected on the Login.html page. Currency: ZPF Sales Origination: 02CA these are the values that it's supposed to have. Hopefully this gives you guys an idea, because unfortunately I don't know much about JavaScript, so looking for some help from the pros I wasnt sure where to put this one, since its mainly javascript I thought I would put it here. I am trying to pull a value being stored in a php function (it works fine) which is echoed into an html element, and use it in a javascript function. my HTML: Code: <img id="menu_image" src="<?php echo get_php_value(); ?>" width="356" /> my javascript: Code: function get_large_image(){
var image = document.getElementById('menu_image').src;
alert(image);
}
right now the alert is giving me flie path to the current page, I need a file path to the image. When I had javascript pull a value from an input tag using the id to reference and stored the php function in the value attribute, I got this: "object HtmlElement" The final purpose of all this is to modify dynamically and HTML <a>'s href and class attribute based on a certain condition being true. apprecaite the help Hi i used cookies to store data using java script with 2 calculators, but there is a 3rd calculator that the cookies arent storing, can someone help me figure out where to implement the script?
anyone can help me in cookie ? i couldn't get it to work. My objective is when i click the submit button in the guestbook page, the cookie will then capture just the 'name' and display it out in thankyou page. guestbook page var seconds = 0; function startTimer() { window.setInterval("updateTime()", 1000); } function updateTime() { seconds++; soFar.innerText = seconds; } function validate_email(field) { with (field) { apos=value.indexOf("@"); //find the position of the @ character dotpos=value.lastIndexOf(".");// find the last position of the . character if (apos<1||dotpos-apos<2) { alert("Not a valid e-mail address!"); return false; } } } function validate_length(field) { with(field) { if (value.length == 0) { alert("Please fill up the column!"); return false; } } } function getCookie(NameOfCookie){ if (document.cookie.length > 0) { begin = document.cookie.indexOf(NameOfCookie+"="); if (begin != -1){ begin += NameOfCookie.length+1; end = document.cookie.indexOf(";",begin); if (end == -1) end = document.cookie.length; return unescape(document.cookie.substring(begin, end)); } } return null; } function setCookie(NameOfCookie, value, expiredays) { var ExpireDate = new Date (); ExpireDate.setTime(ExpireDate.getTime() + (expiredays * 24 *3600 * 1000)); document.cookie = NameOfCookie + "=" + escape(value) + ((expiredays == null)?"" : ";expires=" + ExpireDate.toGMTString()); } function delCookie (NameOfCookie){ if (getCookie(NameOfCookie)){ document.cookie = NameOfCookie + "=" + "; expires=Thu,01-JAN-70 00:00:01 GMT"; } } function validate_form(thisform) { with (thisform) { if (validate_length(yourname) == false) { yourname.focus(); return false; } if (validate_length(email)==false || validate_email(email)==false) { email.focus(); return false; } if ( ( document.contact_my.gender[0].checked == false ) && ( document.contact_my.gender[1].checked == false ) ) { alert ( "Please choose your Gender: Male or Female" ); valid = false; contact_my.focus(); return false; } } } </script> <form name="contact_my" action="thankyou.html" onSubmit="return validate_form(this)" && onClick="setCookie" method="post" > <input type="submit" value="Submit"> <input type="reset" value="Reset form" onClick="delCookie( 'username' )"> thankyou page function getCookie(NameOfCookie){ if (document.cookie.length > 0) { begin = document.cookie.indexOf(NameOfCookie+"="); if (begin != -1){ begin += NameOfCookie.length+1; end = document.cookie.indexOf(";",begin); if (end == -1) end = document.cookie.length; return unescape(document.cookie.substring(begin, end)); } } return null; } function setCookie(NameOfCookie, value, expiredays) { var ExpireDate = new Date (); ExpireDate.setTime(ExpireDate.getTime() + (expiredays * 24 *3600 * 1000)); document.cookie = NameOfCookie + "=" + escape(value) + ((expiredays == null)?"" : ";expires=" + ExpireDate.toGMTString()); } function DoTheCookieStuff() { username=getCookie ('username'); if ( username!=null ) {document.writeln ('Hi there '+username+' - Good to see you again!')} } Hey guys, i'm trying to incorporate cookies with the website i'm working on. I've looked at tutorials where they just hand you the code and say "get on with it", this leaves me in the lurch while trying to debug it... so the question is are there any good javascript cookie tutorials that will "explain what the heck this does?" Thanks Al. I have been looking all over the web for a solution, because my website displays funky in safari. To fix this i figured i'd tell users that if they are using safari, then using javascript, i could tell them a message. Originally i tried detecting safari then displaying a message. But i couldn't ever find a browser detection for safari. So i thought wait.... If i could: 1. get a javascript alert saying my message. 2. time that message alert frequency by a session, say 10 days? or even every browser session... Then i could solve my problem. However i can't figure out any of this. So if anybody would be willing to help, i'd be very grateful. Hi, I have a website where the user can navigate different categories by tab. The problem is, when they're on a tab other than the default one and they refresh the page or click to another page, it puts them back on the first tab. I know this can be solved by using a session cookie of some type, I just need some help on implementing it into my site. http://www.thatswhyimbroke.com/ - so you can see what i'm talking about. If you look at the different tabs: Price High, price low, food & drink, etc. I want the user to be able to go to one of those, click to page 2 or refresh, and still be on that tab. Any help would be much appreciated! hello everybody, here I'm asking for help again. sorry for that in advance. anyhow, I have the following code: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

I want the lightbox window open only once a day for every unique visitor on my website. I understand I should use some sort of cookie implented, but I dont really understand how to. Thanks in advance, daniel. I am creating a cookie that increases a "value" or "integer" by 1 (ie Y+1) every time any page inside my webpage. Any webpage that i put the code into. right now I need it so that when you visit a page with the code it increases the variable or "cookie" (Y) by 1. when Y reaches a certain number, I.E 10, it resets Y to "0" and redirects you to a URL. Please explain where each value would go in any replies. Please make code as simple and as low in file size as possible. I don't need any sort of flexibility, just a simple redirect to a webpage which WILL NOT have the cookie code in it. EX: when opening the menu of an iPod game it asks you to rate the game, saying remind me later resets the value to "0" and saying rate now, resets to "0" but does not keep counting on the next page. Thanks to all in advance and i hope you completely understood my problem and question! [spoiler] Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

Hi all Experts I am in a need of a simple javascript script that can verify if a cokie exist If it exist: (replace the below and show) You already upgraded. If not exist: I would like it to show: You account is not upgraded yet Please upgrade your account, click here to upgrade<br> <center><A href="url"><img src="picture"></center> also need seperate script to set the cokie Hope u understand what I want thank you I need some help for University cousework that has been sent and I hope someone here can help. I need to create a cookie (easy enough) and then populate that cookie with a word that is selected when you click a certain image. Imagine you have image1.jpg and image2.jpg when a user selects image1.jpg the cookie needs to store image1 and load page2.html If the user selects image2, then page2.html still needs to load but store the word image2 in the cookie. On the next page, the cookie is loaded and the page needs to load the css file associated with that word example: image1 = firstcss.css image2 = secondcss.css Is this possible? Thank you for all your help Hello, Could anyone help me? I'm looking for a script that remembers, re-sets, and can set to the previous state the show or hide behavior of a layer upon return to the page. I have an image gallery that's in 3 categories: wedding, bridal shower and save-the-dates. When viewing an image in the bridal shower or save-the date galleries and I press on the link I created titled "Back to Gallery" it does not return me back to the Bridal Shower or Save-the-dates gallery (whichever I'm in) it returns me to the main Invitations gallery page. So bascially I'm looking for a script that will write to a cookie what layers are shown and what are hidden so when you return it reads the cookie and displays the last layers you had showing before leaving the page. Hi everyone, I am using a jQuery cookie script to set the cookie of some elements on my website. One of the problems is that I need the cookie to not expire after one day, I need it to expire after a while (I'm going to start off with a year).

First problem: I have a script that allows ONLY numbers to be typed into a text field. I have tried to modify this script to allow Decimals (periods) to be typed as well, but haven't succeeded. The code in Red are the changes I added to this script, but it isn't working out. Code: function numbersOnly(evt) {
var charCode = (evt.which) ? evt.which : event.keyCode
if (charCode > 31 && (charCode < 48 || charCode > 57) && (charCode < 110 || charCode > 110) )
return false;
return true;
}
Second Problem: I need to set a Minimum number users may type in the text field. Normally this would be a simple task, but the minimum number they may type is a decimal (0.10). The default value in the field is .50. I tried replacing the .50 with .09, and I can't get the field to run the script and set its new value to .10 (<- this is the minimum). Here is the code I am working with. Code: <?php
$memberType = "free";
$creditsBalance = .5;
$bannerBalance = 1000;
$textBalance = 1000;
?>

<head>
<title>Convert Credits</title>

Hi im kind of new to cookies in Javascript. But after reading a few tutorials on how the work I started to wonder. Is it possible to grab a cookie made by my phpbb forum? I would love to be able to login on my site using my phpbb forum cookies. Anway if this is a bad idea ore won't work for any reason plz let me know. Thanks Hello. I am a neewb, so bare with me. This code is not working correctly for some reason. If I use it in Internet Explorer it will work, but only if you bring up the history in the url tab. You cannot refresh it for whatever reason. so basically it works in Explorer but no refresh. The big problem is Mozilla. I will not work at all. I have all of the cookies set for third party, remember last visit and so on. It will only display the welcome page for first time visitor. Then it will show the subsequent page, however it will not increment the count +1. I am not sure what is going on here, Explorer works, but with no refresh, and Mozilla does not really work at all? Here is my script currently: <script type="text/javascript"> /* <![CDATA[ */ function hitMySite() { var lastDate = new Date(); lastDate.setMonth(lastDate.getMonth()); var dateString = (lastDate.getMonth() + 1) + "/" + lastDate.getDate() + "/" + lastDate.getFullYear(); if (document.cookie != "") { counter = document.cookie.split("=")[1]; counter = parseInt(counter) + 1; date = document.cookie.split(":")[2]; var expireDate = new Date(); expireDate.setMonth(expireDate.getMonth() + 12); document.cookie = "counter=" + counter + ":date:" + dateString + ";expires=" + expireDate.toGMTString(); document.write("<h1>You last visited this page on: " + date + "<br />You have been to this page " + counter + " times.</h1>"); } else { document.write("<h1>Welcome to my Web site! This is your first visit here so be sure to bookmark my page!</h1>"); var counter = 1; var expireDate = new Date(); expireDate.setMonth(expireDate.getMonth() + 12); document.cookie = "counter=" + counter + ":date:" + dateString + ";expires=" + expireDate.toGMTString(); } } /* ]]> */ </script> </head> <body onload="hitMySite()"> </body> </html> Hi im new to working with cookies so would appreaciate a little help I using the w3c tuturial as a template so heres a link so you can see what im trying to do http://www.w3schools.com/JS/js_cookies.asp Code: function getCookie(c_name)
{
var i,x,y,ARRcookies=document.cookie.split(";");
for (i=0;i<ARRcookies.length;i++)
{
x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
x=x.replace(/^\s+|\s+$/g,"");
if (x==c_name)
{
return unescape(y);
}
}
}
function setCookie(c_name,value,exdays)
{
var exdate=new Date();
exdate.setDate(exdate.getDate() + exdays);
var c_value=escape(value) + ((exdays==null) ? "" : "; expires="+exdate.toUTCString());
document.cookie=c_name + "=" + c_value;
}
function checkCookie(username)
{
var username=getCookie("username");
if (username!=null && username!="")
{
document.getElementById("feedback").innerHTML = " last time you scored " + username);
setCookie("username",username,365);
}
else
{
if (username=null || username="")
{
setCookie("username",username,365);
}
}
}
I kept the variable names the same so you can follow and I don't confuse myself and make things more complected while im trying to debug it. Some extra information. checkcookie is been given a variable it is just a simple number. Im making a questionnaire which is done but I wont the top of the page to tell the user how much they scored last or tell them this is their first time trying it. The variable being passed to check cookie is their score . at the moment when I click the submit button nothing happens. Where it should trigger a score calculating function which should then call the checkcookie function while passing the score it calculated. I would love if someone can point me in the right direction or help me correct it or atleast explain to me whats going wrong. Thanks and a lots of appreciation if anyone can spare the time Hi everyone! Got a quick (cookie) question. I looked on the internet for some cookie scripts (redirect ones), but unfortunately haven't been too lucky with these. What I want to do is the following: When the cookie is not found it goes to my main page, for example: "www.anynamehere.com" On the main page I can select where I want to go - 'Contacts', 'News', 'Forums' and so on. The main page has a drop down list with these options, each option has it's own link. When I click on 'continue' and go to the specific link (ex. www.anynamehere.com/contacts.html) it should remember my selection, so next time I log into www.anynamehere.com it's automatically will take me to contacts.html. I will not see the main page anymore. Now, if from the contacts page I select 'News' and go to www.anynamehere.com/news.html it has to remember that link as well. So if I close my browser and then reopen it, it should take me to www.anyname.com/news.html. I hope that makes sense. If anyone can give me any pointers I would greatly appreciate it. Maybe there is a script like that available online, I just wasn't lucky enough to find one. Thank you in advance! I'm new to using cookies. I am using JavaScript for a web project and I'm using cookies and I have 5 links for different movie trailers and I have a trailers.html page with a div with a id="movie" and want to know so that when you click on a Movie trailer link so that it stores a value in a cookie so that you can check on the trailers page which trailer was chosen and display in the div tag
