整理了两种简单的
javascript操作cookie写法,均有三个功能:设置cookie、查询cookie、删除cookie。第一种简单易懂,第二种封装使用方便。原生
js设置cookie。
简单版:
function setCookie(name, value, iDay) {
var oDate = new Date();
oDate.setDate(oDate.getDate() + iDay);
document.cookie = name+'='+value+';expires='+oDate;
}
function getCookie(name) {
var arr = document.cookie.split('; ');
var i = 0;
for(i=0; i<arr.length; i++) {
var arr2 = arr
.split('='); if(arr2[0] == name) {return arr2[1];} } return ''; } function removeCookie(name) { setCookie(name,'',-1); }封装版:var cookie=new function(){ this.set=function(name,value,hours){ var life=new Date().getTime(); life+=hours*1000*60; var cookieStr=name+"="+escape(value)+";expires="+new Date(life).toGMTString(); document.cookie=cookieStr; }; this.get=function(name){ var cookies = document.cookie.split(";"); if(cookies.length>0){ var cookie=cookies[0].split("="); if(cookie[0]==name) {return unescape(cookie[1]);} } return null; }; this.remove=function(name){ var cookieStr=name+"="+escape('null')+";expires="+new Date().toGMTString(); document.cookie=cookieStr; }; } 更多javascript入门知识:。 http://www.iiwnet.com/javascript/
