how to make email submit button use default email program

Yes, the Submit button function will automatically open the default email application of the user. Your task is to determine in what format (html. pdf, fdf) you want to receive the completed form. You can set these parameters in the Submit button properties dialog box.

Here are two button JavaScripts that you might consider:

Example 1
this.mailForm(true);

Example 2:

var cResponse = app.response({
cQuestion: "To copy yourself, enter your email address. Click cancel to send data without sending a copy to yourself",
cTitle: "emailAddress", }); // title of the dialog box
{
if ( cResponse == null)
this.mailForm(true, "xxx [at] yourcomany [dot] com", "", "", "Purchase Order");
else
this.mailForm(true, "yyy [at] yourcomany [dot] com", cResponse, "", "Purchase Order");
}
