jQuery check if Cookie exists, if not create it

Question

I cannot get this code to work I must be missing something pretty simple. I am trying to check to see if a Cookie exists, if it does {do nothing} if it doesn\'t {create it}

Answer 1

I think the bulletproof way is:

if (typeof $.cookie('token') === 'undefined'){
 //no cookie
} else {
 //have cookie
}

Checking the type of a null, empty or undefined var always returns 'undefined'

Edit: You can get there even easier:

if (!!$.cookie('token')) {
 // have cookie
} else {
 // no cookie
}

!! will turn the falsy values to false. Bear in mind that this will turn 0 to false!
