Creating a signature field in a PDF using JavaScript

[Julio Cesar Llavilla Ccama]

I want to create a field in which a signature can be inserted something like what is indicated in the documentation:

https://www.pdftron.com/documentation/web/guides/interacting-with-signature-field/

   <script>

    WebViewer({

      path: 'lib/',

      fullAPI: true,

      initialDoc: 'example0006.pdf',

      //config: 'config.js',

    }, document.getElementById('viewer')).then(async instance => {

      const { Annotations, annotManager, PDFNet, CoreControls, signatureWidgetAnnots, docViewer  } = instance;

      const createSignHereElement = Annotations.SignatureWidgetAnnotation.prototype.createSignHereElement;

      Annotations.SignatureWidgetAnnotation.prototype.createSignHereElement = function() {

        const signHereElement = createSignHereElement.apply(this, arguments);

        signHereElement.style.background = 'red';

        return signHereElement;

      }

    });

  </script>

I have tried everything and it has not worked for me, please if anyone knows how it works I will appreciate it very much.

Hi there, 

Thanks for reaching out!

If you would like to add a signature field to a PDF directly in the web browser, you can take a look at this sample: https://www.pdftron.com/samples/web/samples/forms/form-builder/#. 

The sample code is available in the `WebViewer/samples/forms/form-builder` if you download the WebViewer folder and also available online: https://www.pdftron.com/documentation/samples/js/form-builder/
