基于jQuery的时间戳与日期间的转化

本文实例为大家分享了jQuery时间戳与日期间的转化代码，供大家参考，具体内容如下

背景：

需求如图：

直接上代码，所有的内容都在注释里：

/**
 * 格式化时间：补0操作
 * */
function supplement(num){
  if(parseInt(num) < 10){
    num = '0'+num;
  }
  return num;
};

/**
 * 格式化时间：拓展jquery的全局变量
 * */
$.extend({
  JTime:{
    //当前时间戳 秒：如果要毫秒就不除以1000
    newTime: function(){
      //本地时间然后在转为时间戳，没有时区区别 == Date.now()
      return Date.parse(new Date())/1000;
    },
    //日期格式(YY-mm-dd HH:MM:SS)转时间戳（秒）
    DateToTamp: function(oString) {
      var f = oString.split(' ', 2);
      var d = (f[0] ? f[0] : '').split('-', 3);
      var t = (f[1] ? f[1] : '').split(':', 3);
      //使用Date的构造函数，实力化并解析
      return (new Date(
        parseInt(d[0], 10) || null,
        (parseInt(d[1], 10) || 1) - 1,
        parseInt(d[2], 10) || null,
        parseInt(t[0], 10) || null,
        parseInt(t[1], 10) || null,
        parseInt(t[2], 10) || null
      )).getTime() / 1000;
    },
    //时间戳（秒）转日期时间格式(YY-mm-dd [HH:MM:SS])：有条件的转（时间戳， 是否解析时间，时区：中国=8）
    TampToDate: function(unixTime, isFull, timeZone) {
      //时区处理
      if (typeof (timeZone) === 'number'){
        unixTime = parseInt(unixTime) + parseInt(timeZone) * 60 * 60;
      }
      var time = new Date(unixTime * 1000);
      var ymdhis = "";
      ymdhis += time.getUTCFullYear() + "-";
      ymdhis += (time.getUTCMonth()+1) + "-";
      ymdhis += time.getUTCDate();
      //需要完整的就设置true
      if (isFull === true){
        ymdhis += " " + time.getUTCHours() + ":";
        ymdhis += time.getUTCMinutes() + ":";
        ymdhis += time.getUTCSeconds();
      }
      return ymdhis;
    },
    //时间戳（毫秒）转日期时间格式
    TampToDatetime: function (str) {
      var oDate = new Date(str),
        oYear = oDate.getFullYear(),
        oMonth = oDate.getMonth()+1,
        oDay = oDate.getDate(),
        oHour = oDate.getHours(),
        oMin = oDate.getMinutes(),
        oSen = oDate.getSeconds(),
        oTime = oYear +'-'+ supplement(oMonth) +'-'+ supplement(oDay) +' '+ supplement(oHour) +':'+ supplement(oMin) +':'+supplement(oSen); //按格式拼接时间
      return oTime;
    }
  }
});
