本文实例讲述了JS实现清除指定cookies的方法，非常实用。分享给大家供大家参考。
具体实现代码如下：
function GetCookieValue(name) {
var cookieValue = null;
if (document.cookie && document.cookie != '') {
var cookies = document.cookie.split(';');
for (var i = 0; i < cookies.length; i++) {
var cookie = jQuery.trim(cookies[i]);
//PYYH=USERNAME=steven&PASSWORD=111111&UserID=1&UserType=1
if (cookie.substring(0, name.length + 1) == (name + '=')) {
cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
//USERNAME=steven&PASSWORD=111111&UserID=1&UserType=1
break;
}
}
}
return cookieValue;
}
function DelCookie(name) {
var exp = new Date();
exp.setTime(exp.getTime() + (-1 * 24 * 60 * 60 * 1000));
var cval = GetCookieValue(name);
document.cookie = name + "=" + cval + "; expires=" + exp.toGMTString();
}
function exit() {
DelCookie("PYYH");
window.location.replace("http://localhost:7877/index.aspx");
}
