JavaScript date calculation example analysis_javascript skills

The examples in this article describe javascript date calculation. Share it with everyone for your reference. The details are as follows:

function setLeaveDate(){
  var inDay=$("#date_6").val();
  // 获取的日期格式为2014-07-03
  var date=inDay.split('-');
  // 将日期分隔成数字
  var num=$(".time_lk").val()*1;
  // 需增加的天数
  var year=date[0]*1;
  var month=date[1]*1;
  var day=date[2]*1+num;
  var d = new Date(month+"/"+day+"/"+year);
  // 得到一个日期对象,注意:这里的月与日历是对应的
  var weekday=new Array(7);
  // 添加一个解析星期显示的数组
  weekday[0]="周日";
  weekday[1]="周一";
  weekday[2]="周二";
  weekday[3]="周三";
  weekday[4]="周四";
  weekday[5]="周五";
  weekday[6]="周六";
  month=d.getMonth()+1;
  // 注意:这里的月份依然变了,月份的索引为0~11,
  //故此在此处加1才会变回与日历对应的月份.
  result=month+"月"+d.getDate()+"日<br>"+weekday[d.getDay()]+"离店";
  $(".time_2").text(result);
}

I hope this article will be helpful to everyone’s JavaScript programming design.
