I already have a script that check for the cookies existence, but i need it to get the cookies value so i can use it in a url like this:
var lang = cookievalue;
location.replace(window.location.protocol+"//"+document.domain+"/"+cookievalue+window.location.pathname);
so what would be the easiest way to simply get the value of a cookie through javascript, everything i've looked for seems to involve spliting the value and stuff,w hich is not necesary since theres simply only one value (en,fr,es etc)
function getCookieValue(key) {
var cookies = document.cookie.split('; ');
for (var i = 0, parts; (parts = cookies[i] && cookies[i].split('=')); i++) {
if (decode(parts.shift()) === key) {
return decode(parts.join('='));
}
}
return null;
}
function decode(s) {
return decodeURIComponent(s.replace(/\+/g, ' '));
}
Then, to get a value for a cookie named my_cookie_name
, you would use getCookieValue('my_cookie_name')
.
Also as an alternative , you can use the jquery-cookie
plugin. It's very simple to use ( $.cookie('my_cookie_name')
) and lightweight.
