Convert simple VBA code to Javascript

[wpryan]

Hello all,
I want to enable some checkboxes in based on the input of an option button using Javascript for a PDF document. I have no experience with Javascript, so I was hoping someone could help me. The VBA code is like this:

Private Sub Opt_1_AfterUpdate()
    If Opt_1.Value = True Then
        CheckBox1.Enabled = False
        CheckBox2.Enabled = False
        CheckBox3.Enabled = False
        CheckBox1.Value = False
        CheckBox2.Value = False
        CheckBox3.Value = False
    End If
End Sub

Private Sub Opt_2_Click()
    If Opt_2.Value = True Then
        CheckBox1.Enabled = True
        CheckBox2.Enabled = True
        CheckBox3.Enabled = True
    End If
End Sub

Thanks in advance.
