Evaluating Multiple Sets of Radio Buttons With JavaScript

- You're not accessing the fields correctly.
- You're not hiding the fields correctly.

Have a look here: http://www.adobe.com/devnet/acrobat/javascript.php
Look especially at the Field object and the Document object's method getField.

try67,

Thanks, but I am a JavaScript novice. I could not understand most of the stuff I read in the references you provided.

Could you just tell me how to access the fields correctly?

Let's back up a little bit. Was this form created in Acrobat or LiveCycle Designer?

Once this is known then we can give you the correct syntax.

BTW, the correct place to perform this action, hiding and showing the banner fields, is in the calculation event for "eAuthBanner".

thomp,

I created the form in Acrobat. I set the mouse up action on each radio button to run a Javasript and you saw the Java Script I wrote.

-Thanx for the quick response

To get the value of a field use this code:

this.getField("btneAuth1).value;

So your script is actually pretty close, just missing some details. If you were to place the hide/show code in the calculation event of the banner field, instead of the MouseUp event of the radio buttons, it would look like this;
event.target.hidden = !( (this.getField("btneAuth1).value=="eAuth1Yes") && (...) )
The calculation event is called anytime the user changes a field so all your code is in one place and activated at the right time.

thomp,

Thanx a million.

Does the exclamation point following the equal sign make this "not equal"? The reason I ask is the initial form has this text box hidden and I only want it to show if 'yes' is selected on all three sets of radio buttons.

You can just tell I'm a nervous novice cantcha :-)

Yes, the "!" is the logical inversion operation, commonly refered to as a "bang". If all three are set to yes, given that your button export values are set correctly, then the result of the logical AND, "&&", will be TRUE. The bang will invert this to FALSE which makes the field visible. Otherwise the field's hidden property will be set to "TRUE".Thom Parker

One small note. The hidden property has been superseded by the display property.

To hide a field, use: .display = display.hidden;
To show a field, use: .display = display.visible;

(If you do make the switch, you will also need to adjust the code provided by Thom)

thomp,

"less filling, tastes great!!!"

Thanks again.
