// Set COOKIE
$cookie_name = 'domain[user]';
$cookie_value = 'domain[id]';
// Cookie need to change right away after user press login
setcookie($cookie_name,$sub_name,time()+(60*60*24),'/');
setcookie($cookie_value,$auth_id,time()+(60*60*24),'/');
// Forced cookie to exit after set
$_COOKIE['domain']['user'] = $sub_name;
$_COOKIE['domain']['id'] = $auth_id;
I am setting my domain name like this on php , but I want to fetch it by JavaScript or jquery, but I have problem getting them.
here is what I have tried.
function readCookie(name) {
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) return c.substring(nameEQ.length,c.length);
}
return null;
}
var value = readCookie('domain["user"]');
alert(value);
how do I get the my cookie info?
You have to decode the cookie before parsing it.
Try this:
function readCookie(cname) {
var name = cname + "=";
var decodedCookie = decodeURIComponent(document.cookie);
//var decodedCookie = "fbm_229931260731834=base_domain=.chris01.com; fblo_229931260731834=y; PHPSESSID=f1djg4brueiqkkqnkjiqj6s5q0; domain[user]=admin; domain[authID]=ba981df7c9aa72ad461461ad524cca01049938f8869098b31065058e7fdaa7e65e3072f637d43c10ba51a5cd6f5ec77d0ccf4befc066320c686168d7638b57e3";
var ca = decodedCookie.split(';');
for(var i = 0; i <ca.length; i++) {
var c = ca[i];
while (c.charAt(0) == ' ') {
c = c.substring(1);
}
if (c.indexOf(name) == 0) {
return c.substring(name.length, c.length);
}
}
return "";
}
var value = readCookie("domain[user]");
alert(value);
Please consider do not call the cookie name like this: readCookie('domain["user"]');
You have to call it like this: readCookie("domain[user]");

I have a cookie on login to a webpage. HEre are the details of the cookie
"{"XXVCode":"T937848","PName":"Garneriere","PAddress":"Dublin 8, southgate","Participation":false,"Coding":true}"
i need to capture XXVCode in a variable how could I do this in javascript on this webpage?
Method 1:
You can use getCookie() function:
// Code collected from w3schools.com
function getCookie(cname) {
var name = cname + "=";
var decodedCookie = decodeURIComponent(document.cookie);
var ca = decodedCookie.split(';');
for(var i = 0; i <ca.length; i++) {
var c = ca[i];
while (c.charAt(0) == ' ') {
c = c.substring(1);
}
if (c.indexOf(name) == 0) {
return c.substring(name.length, c.length);
}
}
return "";
}
Then you can call:
getCookie('XXVCode');
Method 2:
Note: your cookie string wrapped with double quote, it should be wrapped with single quote.
Because double quote inside double quote will show syntax error.
var cookie = '{"XXVCode":"T937848","PName":"Garneriere","PAddress":"Dublin 8, southgate","Participation":false,"Coding":true}';
var cookieArray = JSON.parse(cookie)
const XXVCode = cookieArray['XXVCode'];
convert to object, and then access key
const cookie = "{"XXVCode":"T937848","PName":"Garneriere","PAddress":"Dublin 8, southgate","Participation":false,"Coding":true}"
const cookieJSON = JSON.parse(cookie)
const XXVCode = cookieJSON['XXVCode']
I'm working in an online catalog that is composed by a page (let's call it a) with a div .contenido-catalogo which gets the products through ajax. Those products have a link to another page (let's call it b). The idea is to save page a's .contenido-catalogo in content variable before moving to page b and when the back button of the browser is clicked retrieve the content of the div previously saved. This is my code:
$(document).ready( function () {
var content;
if (getCookie('foo') == 'bar') {
$('#contenido-catalogo').html(content);
setCookie('foo', '');
};
$('body').on('click', '.product-link', function() {
setCookie('foo', 'bar');
content = $('#contenido-catalogo').html();
});
function setCookie(cname, cvalue) {
document.cookie = cname + "=" + cvalue + ';';
}
function getCookie(cname) {
var name = cname + "=";
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);
if (c.indexOf(name) == 0) return c.substring(name.length, c.length);
}
return "";
}
i try write new cookie in ashx file,but i get error
HttpCookie cookname;
for (int i = 0; i < files.Count; i++)
{
HttpPostedFile file = files[i];
string filename = "~/img/" + "111" + file.FileName;
filenames.Add(filename);
file.SaveAs(context.Server.MapPath(filename));
cookname["filename"] = filename;
Response.Cookies.Add(cookname);
}
And how i can get cookie in javascript?
Thank
You have to initialize HttpCookie first with a name like
HttpCookie cookName = new HttpCookie("yourCookieName");
Then add value whatever you want like
cookName["yourPropertyName"] = value;
To get cookie in javascript, you can use following function
function getCookie(cname) {
var name = cname + "=";
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);
if (c.indexOf(name) == 0) return c.substring(name.length,c.length);
}
return "";
}
Then call the function to get cookie like
getCookie("yourCookieName=yourPropertyName")
I am getting quite a frustrating issue with JavaScript and Cookies on cached pages.
I got the following JS code:
function getCookie(cname) {
var name = cname + "=";
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);
if (c.indexOf(name) == 0) return c.substring(name.length,c.length);
}
return "";
}
if (!getCookie("lang") == "{{Lang}}"){
document.reload();
}
{{Lang}} is replaced with the very same cookie on the backend with PHP.
$template = str_replace("{{Lang}}", $lang, $template);
But that is not really relevant since that part works as intended.
The issue is that when the user visits a cached page.
The JS previously mentioned becomes
function getCookie(cname) {
var name = cname + "=";
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);
if (c.indexOf(name) == 0) return c.substring(name.length,c.length);
}
return "";
}
if (!getCookie("lang") == "FR"){
document.reload();
}
The issue is that the page does not refresh even though the Chrome Dev tools quite clearly say that the cookie lang is set to "EN", not "FR".
Is there a method around this caching issue?
The not equal comparison in JS is !=, so
getCookie("lang") != "FR"
The reload method accepts a Boolean flag indicating a force cache refresh. So try:
document.reload(true);
Example, I have this cookie:
$.cookie("foo", "500", { path: '/', expires: 365 });
How do I get the value of that cookie and put it into a variable?
For example (I know this is not correct):
var foo = $.cookie("foo").val();
It's just var foo = $.cookie("foo").
There's no need for a .val() call as you're not accessing the value of a DOM element.
This worked for me
function getCookieValue(cname) { // cname is nothing but the cookie value which
//contains the value
var name = cname + "=";
var decodedCookie = decodeURIComponent(document.cookie);
var ca = decodedCookie.split(';');
for(var i = 0; i <ca.length; i++) {
var c = ca[i];
while (c.charAt(0) == ' ') {
c = c.substring(1);
}
if (c.indexOf(name) == 0) {
return c.substring(name.length, c.length);
}
}
return "";
}
To get the value of a cookie, you can just call it's reference. For example:
$.cookie("foo", "somevalue");
alert($.cookie("foo"));
Will alert:
somevalue
By this way we can access
console.log($.cookie()); //It will gives the all cookies in the form of object
alert($.cookie('foo'));//it will give cookie foo value ie 500
