// end my jsCookies function

// USAGE - get    ::   jsCookies.get("cookie_name_here");  [returns the value of the cookie]
// USAGE - set    ::   jsCookies.set("cookie_name", "cookie_value", 5 );  [give name, val and # of days til expiration]
// USAGE - check  ::   jsCookies.check("cookie_name_here");  [returns only true or false if the cookie exists or not]

Replace 32 line to

return c_name != null && c_name != "";

i used your script before and it was fine but now it seems to be setting individual cookies per page. tested in firefox and chrome. I was setting a cookie on page2 but page3 wouldnt see it.

I changed this line 26:

document.cookie = c_name + "=" + escape(value) + ((expiredays == null) ? "" : "; expires=" + exdate.toUTCString()) + "; path=/";

and its now a global sitewide cookie.

You have to use some ES6 syntaxis, visit my gist version
