脚本标签、js显示实时时间，兼容谷歌与火狐

        <div class="riqiyou">
          <SCRIPT language=JavaScript>
           var userAgent = window.navigator.userAgent.toLowerCase();
     todayDate = new Date();
     date = todayDate.getDate();
     month= todayDate.getMonth()+1;
     year= todayDate.getYear();
           if(userAgent.indexOf("firefox")>=0||userAgent.indexOf("chrome")>=0||userAgent.indexOf("opera")>=0){
            year+=1900;
           }
     document.write(" 今天是")
     document.write(" ")
     document.write(year);
     document.write("年");
     document.write(month);
     document.write("月");
     document.write(date);
     document.write("日");
     document.write(" ")
     if (todayDate.getDay() == 5) document.write("星期五")
     if (todayDate.getDay() == 6) document.write("星期六")
     if (todayDate.getDay() == 0) document.write("星期日")
     if (todayDate.getDay() == 1) document.write("星期一")
     if (todayDate.getDay() == 2) document.write("星期二")
     if (todayDate.getDay() == 3) document.write("星期三")
     if (todayDate.getDay() == 4) document.write("星期四")
  </SCRIPT>

或者直接：

<%=new SimpleDateFormat("yyyy年MM月dd日 EEEE").format(new Date()) %>
