Update a textfield after selecting a radio button option

[RENEDI]

I integrated in a pdf

- two radio buttons which have also their own Javascript

- a new textfield (txt_field)

After clicking

- option 1 the textfield should be updated via Javascript of radio button 1: 

  txt_field="€";

(2) option 2 the textfield should be updated via Javascript of radio button 2:

    txt_field="$;

Result: Nothing happened in the moment

How can I implement this feature?

Thanks for further information!

This JavaScript alone can do nothing. Is there more? What does it say in the console?

Hi MVP and others,
,

I tried following lines (as js for a radio button)

app.alert ("Start javascript");     //has been shown

txt_EINHEIT.value="€";                //is not working

app.alert ("Ende javascript");      //has been shown

Who kows that problem?

That's not how you access a field. Use the getField method.

Hi. Could you explain more about the getField method?

In the Radio Button Properties box, I went to Actions. I don't know the best trigger to select: Mouse Enter or Mouse Exit, maybe? The action I selected is "Run a JavaScript."

I'm familiar with JavaScripts that link dropdown lists with text fields. I don't know how to link radio buttons to text fields.

When I link a dropdown list to a text field, I use:

switch (event.value) {

case "A":

this.getField("Text Field").setItems(["A1","A2","A3"]);

break;

case "B":

this.getField("Text Field").setItems(["B1","B2","B3"]);

break;

}

How do I adjust this JavaScript to work with a radio button instead of a dropdown list? Where do I put it in the Properties box? What trigger should I select?

Thanks for your help.
