</select>

我的脚本

$('select#roomOptions').change(function () {
    $('div#text select').remove();  
    var val = $(this).val();    
    for (var x = 1; x < val; x++) {
       var createSelectBox = '<select id="adults"><option value="1">1</option></select><option value="2">2</option></select><option value="3">3</option></select><select id="children"><option value="1">1</option></select><option value="2">2</option></select><option value="3">3</option></select>';

$('#txtTickets').change(function() {
      var val = parseInt($(this).val(), 10);
      var html = '';
      for (var i = 1; i < val; i++) {
            html += '<select class="adults"><option>One</option><option>Two</option></select><select class="childs"><option>One</option><option>Two</option></select><br>';
      }
      $('#selectContainer').html(html);
});
