javascript操作cookie函数两种简单的写法

function setCookie(name, value, iDay) {
    var oDate = new Date();
    oDate.setDate(oDate.getDate() + iDay);
    document.cookie = name+'='+value+';expires='+oDate+';path=/';
}
function getCookie(name) {
    var arr = document.cookie.split('; ');
    var i = 0;
    for(i=0; i         var arr2 = arr[i].split('=');
        if(arr2[0] == name) {return arr2[1];}
    }
    return '';
}
function removeCookie(name) {
    setCookie(name,'',-1);
}

var cookie=new function(){
    this.set=function(name,value,hours){
        var life=new Date().getTime();
        life+=hours*1000*60*60;
        var cookieStr=name+"="+escape(value)+";expires="+new Date(life).toGMTString()+";path=/";
        document.cookie=cookieStr;
    };
    this.get=function(name){
        var cookies = document.cookie.split("; ");
  var i = 0;
  for(i=0; i    var cookie2=cookies[i].split("=");
   if(cookie2[0]==name) {return unescape(cookie2[1]);}
  }
        return '';
    };
    this.remove=function(name){
        var cookieStr=name+"=''"+escape('null')+";expires="+new Date().toGMTString();
        document.cookie=cookieStr;
    };
}
