Set the value of a radio button with Javascript

[Kris Hunt]

Quick syntax question: If I have a radio button group called "Answer" with the options "Yes", "No", and "Maybe", how can I use Javascript to select one of those options?

this.getField("Answer").value = "Maybe";

Thank you.

On my test form, I have a dropdown menu (named "Selection") where the user makes their selection, and then on another page, that same selection is displayed in a radio button group (named "Result") with that option checked. The export values in the dropdown and the radio button group are the same. Here's what I did:

On the dropdown menu field, I added a Javascript to be executed on MouseUp:

var mySelection = this.getField("Selection").value;

this.getField("Result").value = mySelection;

I also checked the "Commit selected value immediately" option.

It's not working properly; the selections in the radio group are always one selection behind the selections in the dropdown list, exactly as they would be if I had not selected the "Commit selected value immediately" option. What am I doing wrong?

Move it to the Validation event and change the first line to:

var mySelection = event.value;

Hmm... it's not working for me. Would you mind looking at my PDF?

[try67]

Sure. You can share it via Dropbox, Google Drive, Adobe Document Cloud, etc., or you can email it to me directly to try6767 at gmail.com.

I tried sharing it with Dropbox, but I'm not sure if it worked. Here's a link from WeTransfer.

Important to remember: JavaScript is case-sensitive.

[Kris Hunt]

Right... all my export values are in lower case. Do you see a typo somewhere?

[Bernd Alheit]

The export values of the drop down are not lower case.

[Kris Hunt]

Sure they are:

[try67]

Right, but the "event.value" property returns the display value, though.

[Kris Hunt]

Ah.

[try67]

I would recommend getting rid of the export values and changing the values of the radio-buttons to match those in the drop-down.

[Kris Hunt]

Got it, thank you both!
