Is there a way to send form data in the body of an email using javascript ?

Concernant la gestion des caractères accentués il faut absolument lire cet article-tuto :

Hello,

And a big thanks/merci to everyone, that's what I did and it kind of work the way I wanted :

app.mailMsg({
     bUI: false,
     cTo: "paul@studiofables.com",
     cSubject: "J'ai une question pour RNEST",
     cMsg: "Prénom : " + this.getField("Prenom").value +
                "\nNom : " + this.getField("Nom").value +
                "\nOrganisation : " + this.getField("Org").value +
                "\nE-mail : " + this.getField("Mail").value +
                "\nQuestion : " + this.getField("Question").value
});

Vous devriez jetez un œil à ce superbe document d'exemple : https://www.abracadabrapdf.net/pdf-de-demo/formulaires/formulaire-de-contact/

Take a look at the Acrobat JavaScript API document: 

The doc.mailDoc() method has a way to specify all parts of an email message: https://help.adobe.com/en_US/acrobat/acrobat_dc_sdk/2015/HTMLHelp/index.html#t=Acro12_MasterBook%2FJS_API_AcroJS%2FDoc_methods.htm%23TOC_mailDocbc-74&rhtocid=_6_1_8_23_1_73

There is no ready made function that would just add the form contents to the body of an email message, but you can assemble that message as a string, and then use that string to populate the body of your email. It's a bit more complex than just calling a function, but it can be done.
