JavaScript实现字符串与日期的互相转换及日期的格式化

前端之家收集整理的这篇文章主要介绍了JavaScript实现字符串与日期的互相转换及日期的格式化前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

字符串转日期、日期转字符串

/**

  • 字符串转时间(yyyy-MM-dd HH:mm:ss)
  • result (分钟)
    */
    stringToDate : function(fDate){
    var fullDate = fDate.split("-");
return new Date(fullDate[0],fullDate[1]-1,fullDate[2],0);  

}

/**

  • 格式化日期
  • @param date 日期
  • @param format 格式化样式,例如yyyy-MM-dd HH:mm:ss E
  • @return 格式化后的金额
    */
    formatDate : function (date,format) {
    var v = "";
    if (typeof date == "string" || typeof date != "object") {
    return;
    }
    var year = date.getFullYear();
    var month = date.getMonth()+1;
    var day = date.getDate();
    var hour = date.getHours();
    var minute = date.getMinutes();
    var second = date.getSeconds();
    var weekDay = date.getDay();
    var ms = date.getMilliseconds();
    var weekDayString = "";
  if (weekDay == 1) { 
    weekDayString = "星期一"; 
  } else if (weekDay == 2) { 
    weekDayString = "星期二"; 
  } else if (weekDay == 3) { 
    weekDayString = "星期三"; 
  } else if (weekDay == 4) { 
    weekDayString = "星期四"; 
  } else if (weekDay == 5) { 
    weekDayString = "星期五"; 
  } else if (weekDay == 6) { 
    weekDayString = "星期六"; 
  } else if (weekDay == 7) { 
    weekDayString = "星期日"; 
  } 

  v = format; 
  //Year 
  v = v.replace(/yyyy/g,year); 
  v = v.replace(/YYYY/g,year); 
  v = v.replace(/yy/g,(year+"").substring(2,4)); 
  v = v.replace(/YY/g,4)); 

  //Month 
  var monthStr = ("0"+month); 
  v = v.replace(/MM/g,monthStr.substring(monthStr.length-2)); 

  //Day 
  var dayStr = ("0"+day); 
  v = v.replace(/dd/g,dayStr.substring(dayStr.length-2)); 

  //hour 
  var hourStr = ("0"+hour); 
  v = v.replace(/HH/g,hourStr.substring(hourStr.length-2)); 
  v = v.replace(/hh/g,hourStr.substring(hourStr.length-2)); 

  //minute 
  var minuteStr = ("0"+minute); 
  v = v.replace(/mm/g,minuteStr.substring(minuteStr.length-2)); 

  //Millisecond 
  v = v.replace(/sss/g,ms); 
  v = v.replace(/SSS/g,ms); 

  //second 
  var secondStr = ("0"+second); 
  v = v.replace(/ss/g,secondStr.substring(secondStr.length-2)); 
  v = v.replace(/SS/g,secondStr.substring(secondStr.length-2)); 

  //weekDay 
  v = v.replace(/E/g,weekDayString); 
  return v; 
} 

// dateValue=2014-02-28
var cDate = _STAGE.stringToDate(dateValue);
cDate.setDate(cDate.getDate()+1);
currentDate = jAnXin.util.formatDate(cDate,"yyyy-MM-dd");

console.log(currentDate ); // 2014-03-01

正则替换日期并格式化日期

转数字型:

结果:

转日期型:

结果:

超级正则替换:

ttDate = ttDate.replace(/(\d{4}).(\d{1,2}).(\d{1,2}).+/mg,'$1-$2-$3');
alert(ttDate);

结果:
