Try this:
function delete_cookie( name, path, domain ) {
if( get_cookie( name ) ) {
document.cookie = name + "=" +
((path) ? ";path="+path:"")+
((domain)?";domain="+domain:"") +
";expires=Thu, 01 Jan 1970 00:00:01 GMT";
}
}
或：
function delete_cookie( name ) {
document.cookie = name + '=; expires=Thu, 01 Jan 1970 00:00:01 GMT;';
}
