How to test if a JavaScript cookie has expired?

To test if a cookie has expired in JavaScript, add the following condition and check −

if( !($.cookie('myCookie') === null) ) {
   // Do something (cookie exists)
} else {
   // Do something (cookie expired)
}

You can also check it using a single line code −

checkCookie = $.cookie('myCookie') === null ?
( /*Condition TRUE...*/ ) : ( /*Condition FALSE...*/ );
