Conditional formating of three or more checkboxes

It looks like you're mixing code intended for a form created in Acrobat with code intended for a form created in LiveCycle Designer. Which are you using? If Acrobat, what is the export value you set up for CheckBox1 and CheckBox2?

I am using Acrobat Pro 8.1, the export value set up for CheckBox1 and CheckBox2 is Yes for both.

I modified the code to

var cb1 = this.getField("CheckBox1")
var cb2 = this.getField("CheckBox2")
var cb3 = this.getField("CheckBox3")

if (cb3.rawValue = 1) {
cb1.value = "False"
cb2.value = "False"
cb3.value =="True";
}
Now if both CheckBox1 and CheckBox2 are selected and I select CheckBox3 Then Checkboxes 1 and 2 get deselected and CheckBox3 stays selected. I need to work out the logic for the CheckBox1 and CheckBox2 to ensure that if either one is the second Checkbox to be selected then Checkbox3 gets selected and Checkboxes 1 and 2 get deselected.


Thank You for you prompt reply.

If you're using Acrobat, the correct code for the Mouse Up event of Checkbox3 would be something like:

var cb1 = this.getField("CheckBox1");
var cb2 = this.getField("CheckBox2");

// If this check box is selected, deselect the other check boxes
if (event.target.value !== "Off") {
cb1.value = "Off";
cb2.value = "Off";
}

The rawValue property is not a property of acroform fields. It only works with XFA forms created in LiveCycle Designer.

Also, the following line:

if (cb3.rawValue = 1) {

uses the assignment operator (=), not an equality operator (== or ===), which is what you need to use here.

You description of how you want the rest of it to work is not clear to me, so get this working first and post again if you get stuck.

Thanks, I got CheckBox3 to work. Now I need the other 2 to work.

Let me clarify what I am trying to do. Say there is a line in the form
Do you Like:
Red Apples (Checkbox1)
Green Apples (CheckBox2)
Both(CheckBox3).

What I am trying to do is to get Checkbox3 to get checked upon trying to check the second checkbox if the first one is already checked.

PS: The code that I posted also seem to work. I wonder why?

Why not use radio-buttons? They make much more sense in this context.

The only problem is that I am unable to get all three radio buttons in the "off" position, if I so desire.

Then use check-boxes with the same name but different export values.

I thought there could be only "Yes" and "Off" as export values. Hence could only be used for 2 Check Boxes.

You can set the "on" value to whatever you want. It's in the properties window.

I am not sure how to achieve what I want with your suggestion.

Let me try and explain what I am trying to do

Say there is a line in the form

Do you Like: Red Apples (Checkbox1) Green Apples (CheckBox2) Both(CheckBox3)

In the above scenario I would like the following outcomes:

1. If Checkbox3 is checked then Checkboxes 1 and 2 get unchecked
2. If either Checkbox 1 or Checkbox2 is checked and the user decides to check the other Checkbox, either 2 or 1 as the case may be, then for Checkbox3 to be checked and Checkboxes 1 and 2 to be unchecked.
3. All the Checkboxes to remain unchecked

I was able to achieve item # 1 with the above javascript. Item # 3 is possible with Checkboxes. I am having trouble with Item # 2

Thanks for your continued interest

Then use a drop-down box with the following items:
"-", "Red Apples", "Green Apples", "Both"

It just seems unnecessary to me to script it when there are other options which are much more user-friendly and intuitive.

I agree with try67. The behavior you're wanting seems awkward and non-standard and I think this particular question should rethought. It seems more straightforward to include just the first two check boxes and allow them to select none, one, or both.

I agree with you. I will have to make that suggestion to the powers that be. Personally I am switching to pears.
