Ignore open enter key

2

On my system, I created a modal that will serve as an alert whenever the user does some invalid operation.

But to force the user to always close the modal via the close button, I wanted to prevent him from closing the modal by pressing ENTER . Is there anything that does this?

// Get the modal
var modal = document.getElementById('mensagem');

// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];

// When the user clicks on <span> (x), close the modal
span.onclick = function() {
    modal.style.display = "none";
}
.modal {
    position: fixed; /* Stay in place */
    z-index: 1; /* Sit on top */
    padding-top: 100px; /* Location of the box */
    left: 0;
    top: 0;
    width: 100%; /* Full width */
    height: 100%; /* Full height */
    overflow: auto; /* Enable scroll if needed */
    background-color: rgb(0,0,0); /* Fallback color */
    background-color: rgba(0,0,0,0.4); /* Black w/ opacity */
}

/* Modal Content */
.modal-content {
    background-color: #fefefe;
    margin: auto;
    padding: 20px;
    border: 1px solid #888;
}

/* The Close Button */
.close {
    color: #aaaaaa;
    float: right;
    font-size: 28px;
    font-weight: bold;
}

.close:hover,
.close:focus {
    color: #000;
    text-decoration: none;
    cursor: pointer;
}
<div id="mensagem" class="modal" style="display:block">
<input type="hidden" autofocus="true">
  <!-- Modal content -->
  <div class="modal-content">
    <span class="close">&times;</span>
    <p><?=$mensagem;?></p>
  </div>
</div>

You could try, if I'm not mistaken, to apply the onkeypress keyboard event to the span and set it so that when there is a keyboard event nothing happens. Example:

 span.onkeypress = function() {
  modal.style.display = "none";
 }

Then a keyboard event triggers action on the modal. To avoid this, you can pass 'none' to the event. It would look like this:

span.onkeypress = none;

thus avoiding any keyboard events on the span.
