Reading cookies in javascript

Reading cookies in javascript

Because the cookie is the value of the document.cookie object, reading a cookie is as straightforward as creating one. This string may be used to access the cookie at any time. The string has a list of name=value pairs separated by semicolons, where name is the cookie name and value is the string value.

Cookies may be read in JavaScript using the following syntax: 1 var x = document.cookie; Example: By giving the cookie name, you can simply read the cookie using the below method.

var ca = document.cookie.split(';'); /processing to obtain the content 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) { //returning actual content return c.substring(nameEQ.length, c.length); } } return null; }

Example: Using a cookie to store the user's name.

if (cookies == 'yes') { jQuery('document').ready(function () { //reading cookie var cook = readCookie('YourWebsite'); if (cook != 'true') { If the cookie isn't discovered, it'll be created. createCookie('YourWebsite', 'user_name=akash', 30); } }); }
