The signature only appears once the modal bootstrap has been resized

After a user enters data in my application, they are required to sign using the signature-pad plugin found here: https://github.com/szimek/signature_pad. The signature is then placed in a modal created using bootstrap4.

The problem arises when I try to open the modal, as the canvas inside it has dimensions of 0x0 pixels. To fix this issue, I need to resize the screen and initialize the library when the modal is opened.

I have attempted to set the width of the modal-body dynamically, but this did not provide a satisfactory solution. Manually setting the width and height also did not work as expected.

<script>
      $('#myModal').on('show.bs.modal', function (e) {
        console.log("modal open");
        resizeCanvas();
      });
 </script>

Answer №1

Thanks everyone, I was able to figure it out. I set the modal to display:block; and then used jQuery to change it

$(document).ready(function (){
            $('#myModal').css('display','none');
      });

and disabled the screen resize on the signature pad.
