Code That Can Read/write Cookie Collections With Keys?
Jul 23, 2005
I can't find any javascript that reads and writes cookies with keys,
so that it is compatible with ASP (I want to read and write cookies
from both javascript and ASP)
for example in ASP:
<%
Response.Cookies("user")("firstname")="John"
Response.Cookies("user")("lastname")="Smith"
Response.Cookies("user")("country")="Norway"
Response.Cookies("user")("age")="25"
%>
I'm looking for javascript code that can read that information.
I have a script that i need to read the ip from a visitor and set a cookie, so the script will never be executed again for that particular ip address.
Right now i'm having problems with the current cookie set of my script, i can't seem to make it not appear again after it's executed (which is my goal). That's why i want to try using an IP cookie, and see if that works.
I'm trying to read a cookie that I've set with php with javascript. The cookie is for storing the username when logging in to a site. If the cookie has been set I want the focus in the inline popup to target the password field so that the user doesn't have to tab down from the username field of the login form.
The php script stores the cookie perfectly: if (isset($_POST['remember'])){ $expire = time()+60*60*24*30; setcookie("login_username", $username, $expire); echo $_COOKIE['login_username']; } else { if (isset($_COOKIE['login_username']) || isset($_COOKIE['password'])){ $expire = time()-3600; setcookie("login_username", "", $expire); }}
The javascript: if (targetfocus == 'login_username'){ alert(readCookie('login_username')); if (readCookie('login_username') == 'username'){ targetfocus = 'password'; }} $("#"+targetfocus).focus(); ... function readCookie(name) { var cookieName = name + "="; var cookieArray = document.cookie.split(';'); for (var i = 0; i < cookieArray.length; i++){ var cookie = cookieArray[i]; while (cookie.charAt(0)==' '){ cookie = cookie.substring(1,cookie.length); }if (cookie.indexOf(cookieName) == 0){ return cookie.substring(cookieName.length,cookie.length); }return null; }}
But when trying to read the cookie in the javascript code I receive null when I put an alert to the code. Why won't the javascript find the cookie? Is it because I'm running the site localhost on my laptop? Does that have an effect on cookies?
I can't figure out why I am not able to read the cookies sitewide, maybe it is the way I am setting the cookie but the cookie looks to be set correctly in the Firefox browser.
On the page that I set the cookie, it works. I can read the cookies I set on the same page as well.
If I move to another page to view the cookies it gives an undefined value when using the getCookie function.
IF the problem lies in the getCookie function, please explain the code a little to me so I can get an understanding what I missed.
i have a table of images, with onmouseover,onmouseout and click events. The user can select and deselect an image. When an image is selected, the image scr changes.
Then the user can confirm his selections and redirect to another page for the checkout process. When he returns to the first and initial page, i want his selections to have a different image (lets say confirmed.gif).In other words to save his selections in a cookie and return them by changing the images so that they wont be available for selection.
In order to find which images are selected and store them in an array i can use the following loop:
function getSelected(){ var myArray = []; var images = document.getElementsByTagName("img"); for (i=0;i<images.length;i++){
[Code]....
How i can save that array with the images tittles in a cookie, so that when the initial page loads i can find which images to change and then change the image.src to confirmed.gif ?
This code writes a cookie to save the li's position after a user has sorted them to their preference. It's only designed to handle One unordered list. I'm trying to have it handle 3 unordered lists under the same page. It needs to write 3 cookies, and then read them when the user returns.
Code: /// set the list selector var setSelector = ".list1"; // set the cookie name var setCookieName = "listOrder";
Basically am going to make an search script to my website. I am going to use onkeyup event when the user is writing and my problem is that I wont to make a function that takes in input from the user and put it in the url. So I need to be able to write and read from the url without refreshing the page. I've managed to do this using window.location.search but I cant get it to work because the page keeps refreshing.
I downloaded jquery today in the hopes it would speed up my development. but its not working at all.
Ive tried including it as an external js and ive tried it directly on the page. regularjavascript works but not jquery. im using wampserver with short tags turned on.
I would post some code but my special keys do not work in this form for some reason. but i can assure u i have triple checked all the code against many different sources and its correct.
like i said regular javascript works fine but jquery code will not. any ideas on what i should check/try?
I am using a standard javascript that I downloaded from javascriptsource.com to read from and fill in a form using cookies. The page tests well in every browser except Apple's Safari (from 10.3.2)
Unfortunately, my clients daughter uses Safari so I have to get it to work with it, even though most of his clients use IE.
What do I need to do to change the code so this will all work in Safari? Code:
I have now learned how to write to and read from .txt files on my server via php, but is it possible to do this with JavaScript? Like that JavaScript writes to the .txt file every second without needing the user to refresh the page to write or read .txt file (with php). 2: Do the same thing with ActionScript 2/3.
Is there a way I can read my address bar and write the link to a file. I think it is great that websites post the code I need but the cut and paste thing gets to be a drag. If I am using my browser I am not editing my site. I need a way to save from the http and com. are maybe the part between the two dots.
I was wondering if there was a way to dynamically read a field input and respond to it later in the form. My situation is this: I have a question that asks how many workers are employed at a business. Later in the form, the user is asked to add as many workers as they have (section with information on each worker) ..Is there a way I can have something echoed or document.write above the latter section saying "Please add (Number of workers listed above) sections for each worker employed"
The form's drop down menu includes three cities (Calgary, Toronto, Vancouver). When the user presses "submit form", the script should create a cookie to store the user's city selection. Next time the user visits the site, they should be redirected to their city's site, ie. "/vancouver.html"
Right now, the code is returning an error from the onload("redirect();") function. The error indicates I am trying to redirect to "/[object HTMLSelectElement].html", but I am not sure if the trouble is in reading or writing the cookie. For simplicity, I've removed most of the other content from this page (my cookie.js is attached as a .doc):
I am making a php/mysql epos system for my shop which will be run from a browser on my shop PC. I have large buttons which I would like to be able to 'click' by pressing something like the F-buttons at the top of the keyboard. Is it possible to override the standard button shortcuts for a web page. This is only going to be on my shop computer so accessibility is not a problem.
My requirement: Each time a visitor arrives at a specific webpage i want the main image on the page to be different, or more specifically, one of 6 images which will be shown in rotation. Solution: Set a cookie. Each time the visitor access the page read the cookie and display the corresponding image. Then increment the value and rewrite the cookie, so that next time they'll see the next image in sequence. NB: if the cookie does not exist (first timer) or is at 6, then the value is set to zero (and then incremented).
Problem: Can't get my coding to work. Specifically it just doesn't do anything - no error message, no cookie written. I'm a very novice scripter, as in I've cobbled the coding together from bits off the net that i think i've managed to grasp some kind of an understanding of. Very suck it and see - so far lots of sucking and no seeing!
I don't normally use Javascript apart from a few browser workarounds, but I have a requirement to set a country cookie and it was working when all my pages were in the same directory, but now that I've added subdirectories, it sets a new cookie for each directory instead of one sitewide.
Here's the code (which I edited from some found on the internet):
Then on the homepage links I use:
Then on the subdirectory pages, I have a reset button which allows you to return to the homepage and disable the redirect.
So I just need the path=/ to be added somewhere is that right? I tried changing the last line of the main code to:
1 site sets a cookie on your machine when you have logged in.
The other site is a wordpress blog. In the index.php (at the root level), I wanted to basically shield the site from running if this cookie is not found on their machine. If it is, the blog will run like normal.
Is there a way I can do this without doing a bunch of redirects or form postings?
So im working on a case where I need to make a random ad pop up every time I refresh that web page. I've got all the steps down except to where I need to insert a command to write the text to the document.
*Insert a command to write the following text to the Web document:
where URL is the value of the rLink variable, n is the value of the rNumber variable, and description is the value of the rAD variable.
what I have so far (all steps completed) is
<script type="text/javascript"> var rNumber= randInt(5);// generate a random integer from 1 to 5. var rAd= adDescription(rNumber);// description of the random ad.
I'm using a geolocator service to find the zipcode of a web page visitor using the code below. This will be used to serve up ads to the visitor based on their zip code. The question is, how do I pass the zip code value from the script into an ASP variable, such as a cookie or session object?
