Cookie handling

Writing a cookie:

(function(){

// erase any existing instances
eraseCookie('nameOfCookie');

// bind a change event to the cookie
$("input:radio[name:'radioName']").bind( 'change',function(){

//write the cookie
createCookie('extrasCookie',$(this).val(),7);
})
})();



Reading the cookie:

(function(){
if(readCookie('extrasCookie')=="1"){

// do something based on the results

}
})();
