On the HOME page, I write an "x" value in a cookie.
var dataAtual = new Date();
var expire = new Date();
expire.setDate(dataAtual.getDate() + 1);
document.cookie = "NomeCookie=ValorCookie; expires=" + expire.toGMTString();
When accessing the Registration page (for example).
var valor = document.cookie;
The value returns all other existing cookies except the one I just created. How can I solve this? (if possible).
Thank you.
Localhost and Google Chrome / Safari
You are using a Safari or Chrome browser with the http://localhost domain, for some reason these browsers in the localhost domain do not allow front-end technologies to add cookies, a solution attempt is to access via http://127.0.0.1 , if the problem persists you can try to create a "fake" domain by editing hosts (if it is in windows) as I explained in this answer:
Different domains / sub-domains
If you record a cookie via javascript on the http://foo.bar.com page and change to http://bar.com the cookie can not have access
Different levels of folder
If you save the cookie directly it will write to the current folder level, suppose you create a cookie on the page http://site/foo/bar/ it will only be accessible to routes that begin with foo/bar such as:
http://site/foo/bar/ http://site/foo/bar/baz http://site/foo/bar/oi.html In order to work on all levels, just change the path=/ to your script, it will say that the cookie can be accessed from this root (from the url), ie on any page within the same domain, code should look like this:
var dataAtual = new Date();
var expire = new Date();
expire.setDate(dataAtual.getDate() + 1);
document.cookie = "NomeCookie=ValorCookie; expires=" + expire.toGMTString() + "; path=/";
A working example, make sure you can solve your problem by following the step-by-step instructions. I did not identify an error in your script. Functional sample
