1.获取系统的ip地址：

可利用搜狐的IP地址查询接口：[http://pv.sohu.com/cityjson][http_pv.sohu.com_cityjson] (默认GBK)  或：[http://pv.sohu.com/cityjson?ie=utf-8][http_pv.sohu.com_cityjson_ie_utf-8]  (可设置编码)；

function showIP(){
        /**必须引用 http://pv.sohu.com/cityjson?ie=utf-8 */
        document.getElementById("ipAddress").innerHTML = returnCitySN["cip"];
        document.getElementById("cityName").innerHTML = returnCitySN["cname"];
    }

2.获取当前时间：

function showTime(){
        var date = new Date();
        var year = date.getFullYear(); //当前年份
        var month = date.getMonth < 9 ? "0" + (date.getMonth() + 1) : (date.getMonth() + 1); //当前月份(0-11，0代表1月)
        var day = date.getDate() < 10 ? "0" + date.getDate() : date.getDate(); //当前日(1-31)
        var weekday = date.getDay(); //当前星期(0-6，0代表星期日)
        var weekdayArray = ["日", "一", "二", "三", "四", "五", "六"];
        var hours = date.getHours() < 10 ? "0" + date.getHours() : date.getHours(); //当前小时
        var minutes = date.getMinutes() < 10 ? "0" + date.getMinutes() : date.getMinutes(); //当前分钟
        var seconds = date.getSeconds() < 10 ? "0" + date.getSeconds() : date.getSeconds(); //当前秒
        var milliseconds = date.getMilliseconds(); //当前毫秒
        var time = date.getTime(); //当前时间的毫秒数
        var strYMD = date.toLocaleDateString(); //获取当前时间： 年/月/日
        var strTime = date.toLocaleString(); //获取当前时间： 年/月/日 上/下午 时:分:秒
        var str = "";
        str += year + "-" + month + "-" + day;
        str += "  星期" + weekdayArray[weekday];
        str += "  " + hours + ":" + minutes + ":" + seconds + ":" + milliseconds;
        document.getElementById("nowTime").innerHTML = str;
    }
