Setting up an HTML webform with e-signature is a straightforward process.
You'll need to create a new form in your HTML editor, selecting the input fields and e-signature widget from the available options.
The e-signature widget can be customized to fit your brand's style, with options for changing the font, color, and size of the signature field.
With the form set up, you can add a submit button to allow users to send their signed forms.
The next step is to integrate the form with an e-signature service, such as DocuSign or HelloSign, to enable electronic signatures.
You can do this by adding a script to your HTML code, which will connect the form to the e-signature service.
Once integrated, users can sign the form electronically, and you'll receive a notification when the form is submitted.

Setting Up the HTML Structure
Setting Up the HTML Structure is a crucial step in creating an HTML webform with e-signature. The document starts with a standard HTML5 structure, including a head section where required libraries are loaded.
The head section loads two essential libraries: jQuery (v3.6.0) and jSignature (v2.1.2). jQuery simplifies DOM manipulation and event handling, while jSignature enables digital signature capture on an HTML5 canvas.
A form with the id "signature-form" is placed in the body of the document. This form contains several key elements, including a signature capture area with the id "signature".
The form also includes a "Clear Signature" button to reset the signature field and a hidden input with the id "signatureData" to store the captured signature data. A "Submit" button is present to submit the form.

Capturing and Submitting
The signature is extracted as an image in Base64 format when the form is submitted.
This data is then stored in a hidden input field, which can be sent to a server for processing. For demonstration purposes, the script logs the captured signature data to the console and shows an alert.
The signature image is saved as a PNG image in the form owner's Google Drive and a link to the image is saved in the Google Sheet along with the form response.
The signature image can also be sent as an image attachment in the email copy that is sent after the form is submitted.
The electronic signature fields in the form are mandatory, so the form respondent won't be able to submit the form unless they put their signature in the field.
Respondents can submit their signatures on desktop, tablet, and mobile phone.
