Acrobat Professional 9.2.0
 
I am trying to display a message when the user fails to select a checkbox. The code is working, but it is doing the opposite of what I want. It only displays the message when the checkbox is selected.
 
I have a group of 3 checkboxes named payment_option and I have set the export values to 1, 2, and 3. I guess I don't understand how the isBoxChecked works.
 
Here is the code...
  
if (this.getField("payment_option").isBoxChecked(0))
{
app.alert("You have not chosen a payment option. Please choose a payment option before submitting this form.", 3, 0, "Form Completion Instructions");
}
 
I appreciate any help!

Change the first line of the code to this:

if (this.getField("payment_option").isBoxChecked(0)==false)

OK that corrects if for the first checkbox but the other two still display the message when checked.

I would test the value of the check box not being equal to 'Off'.

if (this.getField("payment_option").value == 'Off')
{
app.alert("You have not chosen a payment option. Please choose a payment option before submitting this form.", 3, 0, "Form Completion Instructions");
}The "(0)" references the first created widget of the check box group with the same name and not the entire group of check boxes with the same name.

If you want to use the 'isBoxChecked' method you need to test each widget for not being checked:

if (!(this.getField("payment_option").isBoxChecked(0)) & !(this.getField("payment_option").isBoxChecked(1)) & !(this.getField("payment_option").isBoxChecked(2)) )
{
app.alert("You have not chosen a payment option. Please choose a payment option before submitting this form.", 3, 0, "Form Completion Instructions");
}

If you want to display the message if none of them is selected, use this:

if (this.getField("payment_option").isBoxChecked(0) == false && this.getField("payment_option").isBoxChecked(1) == false && this.getField("payment_option").isBoxChecked(2) == false)By the way, why are you using check-boxes and not radio-buttons for this?

Well I guess I am using checkboxes intead of radio buttons out of habit - no valid reason! I can change it if that makes the form more efficient.

Checking the value of the group does not require editing the script if check boxes are added or removed.

Both Check Boxes and Radio Buttons have a value of 'Off' with there is not selection made. Also the 'isBoxChecked' works the same for the check boxes and radio buttons.
