javascript操作cookie 

<!DOCTYPE html>
<html>
<head lang="en">
    <meta charset="UTF-8">
    <title>cookie</title>
</head>
<body>
由于本地环境只有FF下支持cookie,请在FF下进行测试
<script>
    //document.cookie
    //格式 名字=值

    //在js中等号“=”为赋值，如果对一个变量进行多次赋值，则会产生覆盖
    //在cookie中不会

    document.cookie = "user=blue";
    document.cookie = "password=123";

    var oDate = new Date();
    //alert(oDate.getFullYear()+"-"+(oDate.getMonth()+1)+oDate.getDate());//IE下不能识别"2016-1-12"格式时间，但是能识别"2016/1/12"

    //oDate.setDate(oDate.getDate()+30)当前日期往后30天
    oDate.setDate(oDate.getDate()+14);//14天有效期
    document.cookie = "password=123;expires=oDate";
    alert(document.cookie);


    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("; ");//注意空格不能少

        for(var i=0;i<arr.length;i++){
            var arr2 = arr[i].split("=");
            if(arr2[0] == name){
                return arr2[1];
            }
        }
        return "";
    }
    function delCookie(name){
        setCookie(name, 1,-1);
    }


    var login_proxy = {};
    login_proxy.cookie = { // cookie操作
        get : function (name){
            var arr = document.cookie.match(new RegExp("(^| )"+name+"=([^;]*)(;|$)"));
            if(arr != null){
                return unescape(arr[2]);
            }
            return "";
        },
        set : function (name, value, days,domain){
            if (typeof days == "undefined"){
                domain = domain?domain:'qq.com';
                document.cookie = name + "=" + escape(value) + "; path=/; domain="+domain;
            }else{
                var expdate = new Date();
                var msecs = (typeof days === 'number') ? days * 24 * 60 * 60 * 1000 : 0;
                expdate.setTime(expdate.getTime() + msecs);
                document.cookie = name + "=" + escape(value) + "; path=/; domain=qq.com; expires=" + expdate.toUTCString();
            }
        },
        del : function (name){
            var expdate = new Date();
            expdate.setTime(expdate.getTime() - 1000);
            this.set(name, "", expdate);
