pdf form conditional checkboxes

[jacjohnston]

Hi.

I'm building a pdf form in Acrobat 8 Professional. I want to add JavaScript to 3 checkboxes to achieve the following:

if checkbox 1 or 2 is checked, uncheck checkbox 3; and if checkbox 3 is checked uncheck both 1 and 2.

It seems straightforward, but I have not been able to find a solution either in the Acrobat guide nor online. I have no experience in Javascript other than copying and pasting, so I'm not sure I'm using the right language to search. If anyone can provide any guidance, I would greatly appreciate it.

Thanks a lot!

You could create a function in a document-level JavaScript and call it in the Mouse Up event of each check box, something like:

// Document-level function
function cbControl() {

    // Get a reference to each check box
    var f1 = getField("cb1");
    var f2 = getField("cb2");
    var f3 = getField("cb3");

    // Uncheck cb3 if cb1 or cb2 was selected/deselected
    if (event.target === f1 || event.target === f2) {
        f3.value = "Off";
        return;
    }

    // Uncheck cb1 and cb2 if cb3 was selected/deselected
    if (event.target === f3) {
        f1.value = "Off";
        f2.value = "Off";
    }
}

Change "cb1", "cb2", "cb3" to the names of the check boxes you're using.

Here's the code for each check box's Mouse Up event:

cbControl();

Well, a little bit late but thanks for this anyway. Very helpful.

I've another question related to this matter. How can I make polish this code and apply to various groups of checkboxes without creating an endless list of variables?

function Caselles()

{ 

// Get a reference to each check box 

    var f1 = getField("C1"); 

    var f2 = getField("C2"); 

    var f3 = getField("C3"); 

    var f4 = getField("C4");

    var f5 = getField("C5");

    // Uncheck c2, c3 and c4 if c1 was selected/deselected 

    if (event.target === f1) {

        f2.value = "Off"; 

        f3.value = "Off";

        f4.value = "Off";

    }

    // Uncheck c3 and c4 and check c1 when c2 was selected/deselected 

    if (event.target === f2) {

        f1.checkThisBox(0,true);

        f3.value = "Off";

        f4.value = "Off";

    }

    // Uncheck c4 and check c1 and c2 when c3 was selected/deselected

     if (event.target === f3) {

          f1.checkThisBox(0,true);

          f2.checkThisBox(0,true);

          f4.value = "Off";

    }

    // Check all when c4 was selected/deselected

     if (event.target === f4) {

          f1.checkThisBox(0,true);

          f2.checkThisBox(0,true);

          f3.checkThisBox(0,true);

    }

}

Thanks in advance!
