Validate Required Fields Prior to Applying Electronic Signature

There are a couple of ways to do this. In both methods you have to hide or disable the signature field so the user can't click on it.

1. The easiest way is to create a validate button that runs code for validating the fields and then shows/enables the signature field on a positive result. On a negitive result, use a popup to let the user know they need to change somthing.

You could extend this method to actually start the signature process so the user doesn't have to actually click on the signature field. You wouldn't even have to enable the signature field. Just label the button as "Sign Form"

2. A slightly trickier method is to place an invisible button(that does the same thing as 1) over top of the signature field. The signature field would need to be ReadOnly. When the user clicks on the signature, they are really clicking on the button. You need to set the fields up in the right order to do this.

If you want to show the signature as disabled, here's an article on how to do it.

Thanks for the response this was a big help.

I have created a sign form button that validates the required fields and upon validation it will add a signature field in the appropriate location.

You mentioned in your post that you could extend this method to actually start the signature process, this is what I would like to do but can't seem to find the correct code to make that happen.

Can you point me in the right direction??

Thanks again for all your help.

I was thinking of the "field.signatureSign()" function, but after looking it up in the Acrobat JavaScript Reference its apparent that it can't be run from inside a document script. This function can siliently sign a document or initiate the signing process, depending on the input parameters. But it requires a privileged context.
