I am trying to find out if a cookie exists or not, if it doesn't I want to create it. I am doing this in Internet Explorer and its stopping at if(readCookie(count) == null) of the code below.
if(readCookie("count") == null)
{
createCookie("count", 0, 10);
}
function readCookie(name)
{
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for(var i=0;i < ca.length;i++)
{
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
}
return null;
}
What am I doing wrong here?
if( $.cookie('query') == null ) {
createCookie("count", 0, 10);
}
Try using undefined
instead of null
