Changing enable=true to false in Script Up dialog

[Jean-Claude Tremblay]

A Script UI diagog question... 

How can I change the enabled=true/false status of text a and b text inside a windows script, when the dialog is still open.
I have try adding this at the end but nothing happens.

if (checkbox1.value == true);
a.enabled = false;​

var w = new Window("dialog"); 

    var checkbox1 = w.add("checkbox", undefined, undefined, {name: "checkbox1"}); 
    checkbox1.text = "a check box"; 

var a = w.add('edittext {justify: "center", properties: {name: "a"}}'); 
    a.preferredSize.width = 100; 

var b = w.add('edittext {justify: "center", properties: {name: "b"}}'); 
    b.preferredSize.width = 100; 

var button1 = w.add("button", undefined, undefined, {name: "button1"}); 
    button1.text = "OK"; 

w.show();

Thanks!

Put that code inside the onClick event handler of checkbox. See the following

Add an onClick handler: 

var w = new Window("dialog"); 

var checkbox1 = w.add("checkbox", undefined, undefined, {name: "checkbox1"}); 
    checkbox1.text = "a check box"; 

    checkbox1.onClick = function() {
        if (checkbox1.value == true) { a.enabled = false; }
        else { a.enabled = true; }
    }

var a = w.add('edittext {justify: "center", properties: {name: "a"}}'); 
    a.preferredSize.width = 100; 

var b = w.add('edittext {justify: "center", properties: {name: "b"}}'); 
    b.preferredSize.width = 100; 

var button1 = w.add("button", undefined, undefined, {name: "button1"}); 
    button1.text = "OK"; 

w.show();

Thanks Brian! 
Thanks also Manan for the link. I was not even aware there was a CC2020 API Object Model available.
