How to assign a handler to the edittext element ?

[Andy_Bat1]

Hello everyone.

How to make so that when you input letters in the edittext, button was unlocked ( not empty input value) or blocked (empty value) ?

#target photoshop;
var w = new Window('dialog', '');
w.orientation = "column";

etProd = w.add('edittext',undefined,'');
etProd.preferredSize = [170,20];
btnProd = w.add('button',undefined,"Save");
btnProd.enabled =false;
w.show();

One possibility:

var w = new Window('dialog', '');
w.orientation = "column";
etProd = w.add('edittext',undefined,'');
etProd.preferredSize = [170,20];
etProd.onChanging = function() {
    if (etProd.text) {
        btnProd.enabled = true;
        }
    }
btnProd = w.add('button',undefined,"Save");
btnProd.enabled = false;
w.show();

a second one:

var w = new Window('dialog', '');
w.orientation = "column";
etProd = w.add('edittext',undefined,'');
etProd.preferredSize = [170,20];
btnProd = w.add('button',undefined,"Save");
btnProd.onClick = function() {
    if (etProd.text) {
    alert("etProd-value: " + etProd.text)
    w.close();
    } else {
        alert("No etProd-value")
        }
    }
w.show();
