The Signature Input Web Control collects a user-drawn signature. It is also possible to gather a typed signature with this control.


Note: the Asset that automatically stores the entered signature will be available throughout the duration of a user's Journey but not beyond.

Check Common style properties of web controls for details on how to style this Web Control.


Value Changed

This event is run each time the control receives an input.

Metadata about this event can be accessed through the event namespace.

Example #1

To configure a type signature, on the Web Page that will hold the signature input, create two additional variables of type Text: typed_signature, where the typed signature value will reside and mode , which will contain the current mode of the Signature Input Control. This variable will be used to toggle the appearance of the text input box.

Add the Signature Input to the Web Page. In Data Binding , set the Signature value to typed_signature.  Next, click the '+' icon next to the Signature Input and add the Text Input to the control.

Change the Data Binding on the Text Input to typed_signature. In State set the Is Visible value to:

activity.mode = "type"

On Actions > Value Changed, set activity.mode to event.mode. The mode will either be "draw" or "type."

This configuration will allow the user to type in a signature instead of requiring the drawn signature.

Example #2

The signature control can collect a signature at the end of a legal document.

Add a Signature control to a Web Page. Create an Asset on the Web Page. On the Signature control, set the Signature value to the asset created.
