javascript - 如果选择了选项，则显示 Bootstrap 模式

Question

我有一个包含下拉列表和一些选项的表单:

<select name='type' id='type'>
<option value='suggestions' >Suggestions</option>
<option value='inquiries' >Inquiries</option>
<option value='donations' >Donations</option>
</select>

我还有一个 Bootstrap 模态窗口:

    <!-- Modal -->
    <div id="myModal" class="modal fade" role="dialog">
      <div class="modal-dialog">

        <!-- Modal content-->
        <div class="modal-content">
          <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal">&times;</button>
            <h4 class="modal-title">Modal Header</h4>
          </div>
          <div class="modal-body">
            <p>Some text in the modal.</p>
          </div>
          <div class="modal-footer">
            <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
          </div>
        </div>

      </div>
    </div>

如果选择值“捐赠”，我想显示 Bootstrap 模式。

我试过这样做:

$("#type").bind("change", function () {
    $('#myModal').modal('show')(this.value === 'donations'); 
}).change();

模式默认打开，所以我知道我的目标是模式，但我只想在选择“捐赠”选项时显示。

有什么想法吗？

你这样试试..

$("#type").on("change", function () {        
    $modal = $('#myModal');
    if($(this).val() === 'donations'){
        $modal.modal('show');
    }
});

  $("#type").on("change", function () {        
      $modal = $('#myModal');
      if($(this).val() === 'donations'){
        $modal.modal('show');
    }
 });
