我有两个字段月份名称和日期...当我点击月份名称时，我希望在特定月份中的那个特定月份的日子...（抱歉我的英语不好）

enter image description here

我的月份名称和天数代码...（请为其他任何其他简单代码提供支持）

请添加此脚本（只需在上面的代码下复制粘贴） - 注意：当前年份假定为2017 JS FIDDLE https://jsfiddle.net/sooraz2/f4hb0b5d/ 

 $('.selectmonth').on('change', function(){

 var year = new Date().getFullYear();

 var month = $(this).val();


   var totalDays = new Date(year, month, 0).getDate();

  var options = '<option value="0">Select Day</option>';

  for (var i = 1; i <= totalDays; i++) {

   options+= '<option value="'+i+'">'+i+'</option>';

 }

   $('.selectday').html(options);
})


  var MonthsValue = "<?php $_POST['monthname'] ?>";
   var DayValue = "<?php $_POST['dayname'] ?>";


$(function(){

  $('.selectmonth option[value='+MonthsValue+']').prop('selected', true);
  $('.selectmonth').trigger('change')
  $('.selectday option[value='+DayValue+']').prop('selected', true);

})
