通过javascript的日期对象来得到当前的日期：

var now = new Date();

        var year = now.getFullYear();

        var month = now.getMonth() + 1;

        var day = now.getDate();

        var h = now.getHours();  //时

        var m = now.getMinutes(); //分

        var s = now.getSeconds(); //秒

        var weekday = new Array(7)

        weekday[0] = "星期日"

        weekday[1] = "星期一"

        weekday[2] = "星期二"

        weekday[3] = "星期三"

        weekday[4] = "星期四"

        weekday[5] = "星期五"

        weekday[6] = "星期六"

        document.write(  year + "年" + month + "月" + day + "日" + weekday[now.getDay()]) ;
