Elsewhere on this site, I've seen people ask how to turn-off radio buttons once they've been clicked. And the usual answer is "You can't, so use Checkboxes instead."

Humm... try the following. It wll work with one, two, or two hundred Radio Buttons in a group, but I'll just do two. Adjust to your needs:

Given two radio buttons named "rad"; the first returns a value of "Yes" and the 2nd returns a value of "No"

In the Mouse Up() event of the 1st "rad" button, put the following:

if (this.getField("rad").OldValue == "Yes") {
    this.getField("rad").value = "Off";
}

In the Mouse Up() event of the 2nd "rad" button, put:

if (this.getField("rad").OldValue == "No") {
    this.getField("rad").value = "Off";
}

In the Mouse Down() event of [b]BOTH[/b] buttons, put:

this.getField("rad").OldValue = this.getField("rad").value;
Now, the radio buttons work as usual: select one, the other turns off. But, if you click a button that's currently selected, it turns off, leaving [b]both[/b] buttons [b]off[/b]!

This plays off (no pun intended) the fact that you can create/add any property you want on any object. In this case, we've created a new property named OldValue. Feel free to call it anything you want, like Fred, or something.

Enjoy!

Thanks for this. It's always good to have more options.

Terrill,

I stumbled on your post after posting a similar question. I tried what you had posted and can't seem to get it to work. I'm using Adobe Designer 7.0. I gave two radio buttons the name "test". Both buttons are wrapped in the same redio group.

The mouse UP() event of the first button reads:

if (this.getField("Test").OldValue == "Yes") {
this.getField("Test").value = "Off";
}
The mouse UP() event of the 2nd button reads:

if (this.getField("Test").OldValue == "No") {
this.getField("Test").value = "Off";
}

Both mouse Down() events read:

this.getField("Test").OldValue = this.getField("Test").value;

What am i doing wrong???

I believe the code for the "Mouse Up" action should be testing the "OldValue" and not the value of the the given button. Realizing this and using JavaScript to obtain the field's name, the scripts for the "Mouse Up" and "Mouse Down" actions can be simplified to the following sclripts:

/*Mouse Down action:save the current value of the focused field*/this.getField(event.target.name).oldValue = this.getField(event.target.name).value;

/*Mouse Up action:if the saved value and current value of the focused field are equalthen turn "Off" the all the buttons or boxes with the same name*/if (this.getField(event.target.name).value == this.getField(event.target.name).oldValue)this.getField(event.target.name).value = "Off";

With the use of document level scripts, one could further simplify the code for the Radio or Check Boxes to calling just 2 functions.
