Hello there!

So basically what i want to get is a script that will create a cookie after a function is executed. But on forehand it will be checked if that cookie already exists. When this is the case i don't want the function to be executed.


<script type="text/javascript">
function csearch(DBadblockblocker) {
var str = document.cookie;
var zstr = DBadblockblocker + "=";
var start = str.indexOf(zstr, 0);
if(start == -1) {
// If cookie is not detected -> Check if Adblock is enabled
adblockcheck();
// After the popup a cookie called DBadblockblocker met value true word aangemaakt
document.cookie = "DBadblockblocker=true;path=/";
alert('Cookie is aangemaakt');
// Give alert when cookie has been made
} else {
alert('Cookie bestond al');
// Give alert when cookie already excists
}
}
</script>

I've added these 2 alerts because it was not working, but i just can't find the problem.

Hope you guys can help me!

var start = str.indexOf(zstr, 0);
document.cookie may contain other data other than that you set, therefore the above test is flawed.

Also, having a global object named cookie can conflict with, well I'm not sure, it's either document.cookie or perhaps they have a global already or perhaps it's just a reserved word, etc. In any case, in some browsers it won't work.

for my take on adding/reading/managing cookies.
