            getIPs(function(ip){
                var span = document.createElement("span");
                span.textContent = ip;
                //local IPs
                if (ip.match(/^(192\.168\.|169\.254\.|10\.|172\.(1[6-9]|2\d|3[01]))/))
				document.session = + ip;
                    //document.getElementsByTagName("span")[0].appendChild(span);
                //assume the rest are public IPs
                else
                    //document.getElementsByTagName("span")[1].appendChild(span);
				document.session = + ip;
            });
        </script>

此JS我是在国外找到的,读取访问者的本地内网ip,进行存入session,之后读取出来,请问该如何写?请大神帮忙改一下!谢谢!

js中不能操作session ,session在后头用request获取进行修改。

同意楼上，js确实不能操作服务器session，js要存储的话可以使用cookie, localStorage或sessionStorage

请问怎么JS操作cookie.要怎么改呢?

var utils={
setCookie: function(name, value, options){
var theCookie, now, expires;
if(name && value){
theCookie = name + "=" + encodeURIComponent(value);
}else{
return;
}
if(options && getType(options) == "object"){
if(options.expires){
now = new Date();
expires = now.getTime() + (options.expires * 1000);
now.setTime(expires);
theCookie += "; expires=" + now.toGMTString();
}
if(options.path){ theCookie += "; path=" + options.path;}
if(options.domain){ theCookie += "; domain=" + options.domain;}
}
document.cookie = theCookie;
},
getCookie: function(name){
var cookies = document.cookie,
arr = cookies.split(";"),
arr1;
for(var i = 0; i < arr.length; i++){
arr1 = arr[i].split("=");
if(arr1[0] === name){ return decodeURIComponent( arr1[1] );}
}
return null;
}
}
我写的js cookie读写函数

[麦草CMS]

var getType = function(vari){
var s = Object.prototype.toString.call(vari).toLowerCase().match(/\[object (.*)\]/);
return s[1];
};

var getType = function(vari){
var s = Object.prototype.toString.call(vari).toLowerCase().match(/\[object (.*)\]/);
return s[1];
};

我复制的，删了东西，这个成自执行函数了，这样
function getType(vari){
var s = Object.prototype.toString.call(vari).toLowerCase().match(/\[object (.*)\]/);
return s[1];
};
