가라멜의 달달한 세상 탐방

시간 단위로 선택 가능한 SelectBox를 만들어야 한다..

var $select = jQuery("#bmg_monday_start_hour");
 
for (var hr = 0; hr < 24; hr++) {
 
  var hrStr = hr.toString().padStart(2, "0") + ":";
 
  var val = hrStr + "00";
  $select.append('<option val="' + val + '">' + val + '</option>');
 
  val = hrStr + "30";
  $select.append('<option val="' + val + '">' + val + '</option>')
 
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>
  <select name="bmg_monday_start_hour" id="bmg_monday_start_hour" class="form-control bmg-hrs-mins-input"></select>
</div>
