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"); }
希望本文所述对大家js WEB前端程序设计的学习有所帮助。
