Question

我有一个按钮，在单击添加按钮时添加新的引导日期选择器输入字段。

我面临的问题是当添加新的bootstrap日期选择器输入字段时，它不允许我选择日期，并且那些新添加的bootstrap日期选择器输入字段的大小不同于第一个输入字段

$(document).ready(function() {
  var counter = 2;
  $("#addBtn").click(function() {
    var newRowDiv = $(document.createElement('div')).attr("class", 'row');
    var newStartDateLabel = $(document.createElement('div')).attr("class", 'col-md-2');
    var newStartDateInput = $(document.createElement('div')).attr("class", 'col-md-2', 'input-group', 'input-daterange');

    newStartDateLabel.appendTo(newRowDiv);
    newStartDateLabel.after().html("Start Date " + counter);
    newStartDateInput.insertAfter(newStartDateLabel).html('<input "id="startDate"' + counter + 'name="startDate' + counter + 'type="text class="form-control" >');
    newRowDiv.appendTo(".container");
    counter++;
  });
});

<body>
  <form id="form" name="form" action="DateServlet" method="POST">
    <div class="container">
      <div class="row">
        <div class="col-md-2">
          Start Date 1
        </div>
        <div class="col-md-2 input-group input-daterange">
          <input id="startDate1" name="startDate1" type="text" class="form-control">
        </div>
      </div>
    </div>
    <button id="addBtn" type="button" class="btn btn-default">Add</button>
  </form>
  <script type="text/javascript">
    $('.input-daterange input').each(function() {
      $(this).datepicker("clearDates");
    });
  </script>
</body>

请看下面的代码。具体做出改动：

 var newStartDateInput = $(document.createElement('div'))
                  .attr("class", 'col-md-2 input-group input-daterange');

和

var dateText = $('<input id="startDate' + counter + '" name="startDate' + counter + '" type="text" class="form-control" >');
newStartDateInput.insertAfter(newStartDateLabel).html(dateText);
dateText.datepicker(); //initializing the datepicker on newly added text field
