    1. 获取当前日期(包含时间)字符串:

    // 获取当前时间字符串
    function getCurentTime() {
    var now = new Date();
    var year = now.getFullYear(); //年
    var month = now.getMonth() + 1; //月
    var day = now.getDate(); //日
    var hh = now.getHours(); //时
    var mm = now.getMinutes(); //分
    var ss = now.getSeconds(); //秒
    var clock = year + "-";

    if (month < 10) {
    clock += "0";
    }
    clock += month + "-";

    if (day < 10) {
    clock += "0";
    }
    clock += day + " ";

    if (hh < 10) {
    clock += "0";
    }
    clock += hh + ":";

    if (mm < 10) {
    clock += '0';
    }
    clock += mm + ":";

    if (ss < 10) {
    clock += '0';
    }
    clock += ss;
    return (clock);
    }

    function isNum(e) {
      var k = window.event ? e.keyCode : e.which;
      if (((k >= 48) && (k <= 57)) || k == 8 || k == 0) {

      // 键盘非字母按键无效
      } else {
        if (window.event) {
          window.event.returnValue = false;
        } else {
          e.preventDefault(); //for firefox
        }
      }
    }
