I need the JS to require a user to select at least 1 checkbox, but the user can also select multiple checkboxes. I have a submit button on the form. When the user clicks submit, if they haven't selected one of the check boxes then a message should appear and not let the user submit the email.

I am new to JS, so I would need the code and how to make it work. I am using Adobe Acrobat Standard 9.

Thanks!

You will need something like this:

if (this.getField("checkbox1").value=="Yes" || this.getField("checkbox2").value=="Yes" || this.getField("checkbox3").value=="Yes") {this.submitForm();} else {app.alert("You must check at least one of the check boxes before submitting.");}

You will need to adjust the names and values of the check boxes as well as the proper parameters for submitting the form.

The pop up appears if no check boxes are marked, but it will still create an email to send. Is there a way to prevent it from creating the email when there are no check boxes selected?

You need to use only this code. Don't add any other action to the Submit button, because the validation will not affect those actions. Submitting the form should be done from the code I provided you.

The submit button does not do anything when I click on it now.

If the fields are checked properly, then I would like it to submit the form as a PDF to an email address such as: name [at] mycompany [dot] com.How is done? I appreciate your help. Thanks.

Replace:
this.submitForm();
With this:
this.mailDoc({bUI:true, cTo: "name [at] mycompany [dot] com"});

I found another issue. In addition to those checkboxes, I also have text fields and radio buttons that are required. With this code, they are not being validated any more. They used to be validated when I would click the submit button. A message would pop up as well.

Is there a fix for this?

You will need to expand the script to check those fields as well.
