如果选择了选项，则显示引导模态 [英] Show a bootstrap modal if option is selected

问题描述

我有一个包含下拉菜单和一些选项的表单:

I have a form that contains a dropdown and some options:

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

我也有一个Bootstrap模式窗口:

I also have a Bootstrap modal window:

    <!-- 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>

如果选择了捐赠"值，我想显示Bootstrap模式.

I would like to show the Bootstrap modal if the value "donations" is selected.

我尝试这样做:

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

默认情况下，模态是打开的，所以我知道我以模态为目标，但是我只想在选择捐赠"选项时显示.

The modal is opened by default so I know I'm targeting the modal but I would only like to display when the "donations" option is selected.

有什么想法吗?

推荐答案

您可以尝试这种方式.

$("#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');
    }
 });

<option value='donations' >Donations</option>
</select>
<!-- 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>
