Check if cookie exists if not create it.

Question

TLDR: Want to check if cookie exists, if it doesn't create it.

---

Am using jquery1.4.2 and jquery cookie,

I know this is probably very simple but I just cant get my head right at the moment.

I want to:

1. Check to see if a cookie with name of "query" exists
2. If so nothing.
3. If not create a cookie "query" with a value of 1.

But only if it doesn't already exist.

Thanks in advance

Answer 1

if( $.cookie('query') == null ) { 
    $.cookie( 'query', '1',  { expires: 7, path: '/' } );
}

Answer 2

this??

$.cookie('query', '1'); //sets to 1...
$.cookie('query', null); // delete it...
$.cookie('query'); //gets the value....

if ($.cookie('query') == null){ //Check to see if a cookie with name of "query" exists
  $.cookie('query', '1'); //If not create a cookie "query" with a value of 1.
} // If so nothing.

what more do you want??
