HowTo Delete Cookie Using Javascript

Usually server-side code on dynamic web pages is responsible to manage client cookies (store and delete them). However it is also possible to provide a certain control for cookie management from client code. This is a small javascript trick that demonstrates how to delete cookie using client code. Cookie simply is updated as expired and removed.

< html>
< head>
< title>< /title>
< script language="Javascript">

function loaded()
{
document.cookie = "v0=1;";
document.cookie = "v1=2;";

alert(document.cookie);
}

function deletecook()
{
var d = new Date();
document.cookie = "v0=1;expires=" + d.toGMTString() + ";" + ";";

alert(document.cookie);
}

< /script>
< /head>

< body onload="loaded();">
< a href="javascript:deletecook();">delete cookie< /a>
< /body>
< /html>
