Question

I am using this code to create a cookie with JQuery:

$.cookie('MyCookieName', 'myValueHere');

It works fine but as I have the value assign to a random number it’s generating a new one every reload.

What I need to do is check if cookie has a value and if it’s not empty then don’t create a new one or generate any new value.

Answer 1

if ($.cookie('MyCookieName') == null) {
    $.cookie('MyCookieName','MyCookieValue');
}

You can also add expire time and path in options.

$.cookie('MyCookieName','MyCookieValue', { path: '[path here]', expires: [days] });

Then you can be sure, that cookies won’t be deleted.
