BUG Scenario

Usage Scenario

Trigger the display modal box, fill in the corresponding information, and then submit the form information via ajax Go backstage.

Simplify

Click the button below once to pop up the modal box. Clicking submit will alert("submit") directly. Clicking it once will feel normal, but if you click the modal box several times, you will find that when you click Submit again, the alert will appear multiple times.

Jianshu cannot display the effect. You can refer to the

code as follows:

<button class="btn btn-info" id="modal-click-error">点击弹出模态框</button>

<p class="modal" tabindex="-1" role="dialog" id="myModal">
 <p class="modal-dialog" role="document">
 <p class="modal-content">
  <p class="modal-header">
  <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
  <h4 class="modal-title">Modal title</h4>
  </p>
  <p class="modal-body">
  <p>One fine body…</p>
  </p>
  <p class="modal-footer">
  <button type="button" class="btn btn-default" data-dismiss="modal">取消</button>
  <button type="button" class="btn btn-primary">提交</button>
  </p>
 </p><!-- /.modal-content -->
 </p><!-- /.modal-dialog -->
</p><!-- /.modal -->
$(function() {

 $(&#39;#modal-click-error&#39;).on(&#39;click&#39;, function() {
  $(&#39;#myModal&#39;).modal(&#39;show&#39;);
  
  $("#myModal .btn-primary").on(&#39;click&#39;, function() {
   alert("提交");
  });
 });
 
});

Problem repair

The above js code will be displayed every time the button is clicked. Add corresponding events for the submit button. Just modify it as follows:

$(function() {

 $('#modal-click-error').on('click', function() {
  $('#myModal').modal('show');
 });
 
 $("#myModal .btn-primary").on('click', function() {
  alert("提交");
 });
 
});

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
