截取系统时间 

function showTime() {
    var now = new Date();
    var nowTime = now.toLocaleString();
    var date = nowTime.substring(0,10);//截取日期
    var time = nowTime.substring(10,20); //截取时间
    var week = now.getDay(); //星期
    var hour = now.getHours(); //小时
    //判断星期几
    var weeks = ["日","一","二","三","四","五","六"];
    var getWeek = "星期" + weeks[week];
    //alert(weeks[week])
    var sc;
    //判断是AM or PM
    if(hour >= 0 && hour < 5){
        sc = '凌晨';
    }
    else if(hour > 5 && hour <= 7){
         sc = '早上';
    }
    else if(hour > 7 && hour <= 11){
        sc = '上午';
    }
    else if(hour > 11 && hour <= 13){
        sc = '中午';
    }
    else if(hour> 13 && hour <= 18){
         sc = '下午';
    }
    else if(hour > 18 && hour <= 23){
        sc = '晚上';
    }
    document.getElementById('time').innerHTML ="当前时间：" + date+" " + getWeek +" "+"   "+sc+"  "+time;
    setTimeout('showTime()',1000);
