JavaScript对cookie的增删改查
JavaScript写cookie
function setCookie(c_name,value,expiredays,path) { var exdate=new Date(); exdate.setDate(exdate.getDate()+expiredays); document.cookie=c_name+ "=" +escape(value)+ ((expiredays==null) ? "" : ";expires="+exdate.toGMTString()) + ";" + ((path==null) ? "" : "path=" + escape(path)); } setCookie("qiufeng","www.fengdingbo.com",24); |
JavaScript读cookie
function getCookie(c_name) { if (document.cookie.length>0) { c_start=document.cookie.indexOf(c_name + "="); if (c_start!=-1) { c_start=c_start + c_name.length+1 ; c_end=document.cookie.indexOf(";",c_start); if (c_end==-1) c_end=document.cookie.length; return unescape(document.cookie.substring(c_start,c_end)); } } return ""; } |
JavaScript删除cookie
function delCookie(name) { var date = new Date(); date.setTime(date.getTime() - 10000); document.cookie = name + "=a; expires=" + date.toGMTString() + ";path=*"; } |
JavaScript清除所有cookie
function removeCookie() { var cookie = document.cookie.split(";"); for (var i in cookie) { delCookie(cookie[i].substring(cookie[i].indexOf("="),0)); } } |
