Signature
A built-in JavaScript signature capture widget allows your respondents to add a digital signature to a web form that they fill out. Switch between available front-end frameworks to see a dedicated demo version of an e-signature pad widget for jQuery, React, Angular, Vue, or Knockout. Draw your e-signature with the mouse pointer or your finger on a touch-enabled device to try the functionality.
To add a signature pad JavaScript widget to your survey, define an object with the type property set to "signaturepad" and add it to the elements array. You can also specify penColor and use the signatureHeight and signatureWidth properties to resize the signature box.
The signature can be saved in PNG (default), JPEG, or SVG. Set the dataFormat property to change the format.
