javascript操作cookie简单版本

复制代码 代码如下:

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[i].split('=');

if(arr2[0] == name) {return arr2[1];}

}

return '';

}

function removeCookie(name) {

setCookie(name,'',-1);

}

javascript操作cookie封装版本

复制代码 代码如下:

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;

};

}

留着备用吧
