    javascript - Trigger bootstrap modal if a condition statement is not met - Stack Overflow

    programmeradmin4浏览0评论

    Instead of using the default jquery alert popup, I'd like to trigger a Bootstrap Modal. All the tutorials I've read, the modal is triggered by the click(function(){});. I'd like to have if triggered if a condition in my "if statement" is not met. Here is the code I have 

    var test1 = $('#test').val();

$('#go').click(function() {
  if (test1 === "") {
    alert("Please enter all values in the fields");
    $('#myModal').modal('show');
  }

});
    <script src=".11.1/jquery.min.js"></script>

    Reset to default 7

    In your case, since the modal has an id of id="#myModal", you need to escape the # within the jQuery selector, $('#\\#myModal').modal('show'):

    $('#go').click(function() {
  var test1 = $('#test').val();

  if (test1 === "") {
    $('#\\#myModal').modal('show');
  }
});
    <script src="https://ajax.googleapis./ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<link href="https://maxcdn.bootstrapcdn./bootstrap/3.3.2/css/bootstrap.min.css" rel="stylesheet" />
<script src="https://maxcdn.bootstrapcdn./bootstrap/3.3.2/js/bootstrap.min.js"></script>
<div class="form-group">
  <label for="test" class="col-sm-3 control-label">Test</label>
  <div class="col-sm-3">
    <input type="text" class="form-control" id="test" placeholder="Enter A Value">
  </div>
</div>
<div class="form-group">
  <div class="col-sm-offset-6 col-sm-3">
    <button type="button" id="go" class="btn btn-primary">Go</button>
  </div>
</div>
<!--Modal-->
<div class="modal fade" id="#myModal">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span>

        </button>
        <h4 class="modal-title">Modal title</h4>

      </div>
      <div class="modal-body">
        <p>Please enter all values in the fields.</p>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
    <!-- /.modal-content -->
  </div>
  <!-- /.modal-dialog -->
</div>
<!-- /.modal -->
<!--End Modal-->

    Remove the '#' from the id and your code should work

    <div class="modal fade" id="myModal">
