layui 获取时间和日期（前些天，后些天，当前）

Posted 2022-03-19 每天坚持亿点点

第一:获取当前时间

var now = new Date();

    var year = now.getFullYear();//获取当前年份

    var month = now.getMonth()+1;//当前月份

    if(month<10)

      month = "0" + month;

    else

      month = month;

   

    var day = now.getDate();//当前天份

    if(day<10)

      day = "0" + day;

    else

      day = day;

   

    var time=now.getHours();//当前小时

    var getMinutes=now.getMinutes();//当前分钟

    var getSeconds=now.getSeconds();//当前秒钟

    var time=year+"-"+month+"-"+day+" "+time+":"+getMinutes+":"+getSeconds; //获取当前时分秒

    var datatime=year+"-"+month+"-"+day; //获取当前年月日

第二：获取前些天日期

   var now = new Date().getTime(); //获取毫秒数

    var before = new Date(now - 2 * 86400 * 1000); //这里的2，表示2天前，例如：需要当前日期的10天前，只需要将2改成10就可以了

    var beforeyear = before.getFullYear();

    var beforemonth = before.getMonth()+1;

    if(beforemonth<10)

    beforemonth = "0" + beforemonth;

    else

      beforemonth = beforemonth;

   

    var beforedate = before.getDate();//当前天份

    if(beforedate<10)

    beforedate = "0" + beforedate;

    else

      beforedate = beforedate;

   

        var datatimeOne = beforeyear +"-" + beforemonth + "-" + beforedate;

第三：获取后些天的日期（和前些天一样，只需要把）

 var now = new Date().getTime(); //获取毫秒数

    var before = new Date(now + 2 * 86400 * 1000); //这里的2，表示2天后，例如：需要当前日期的10天后，只需要将2改成10就可以了

    var beforeyear = before.getFullYear();

    var beforemonth = before.getMonth()+1;

    if(beforemonth<10)

    beforemonth = "0" + beforemonth;

    else

      beforemonth = beforemonth;

   

    var beforedate = before.getDate();//当前天份

    if(beforedate<10)

    beforedate = "0" + beforedate;

    else

      beforedate = beforedate;

   

        var datatimeOne = beforeyear +"-" + beforemonth + "-" + beforedate;
