ScriptUI field validation

[Polycontrast]

Can a scriptUI dialog check if the value entered in the text field is valid?

For example, if the field is empty, display an alert that the field can not be empty.

Yes, use edittext.onChanging() event to test as you type and edittext.onChange() to check when you leave the field. Put your validation code in another function that you call.

See this if it's okay for you.

var regExp = new RegExp();
win = new Window("dialog", "TEST",undefined);

var textInput =win.add("edittext", undefined, "TEXT");
textInput.characters = 20;
textInput.active = true;

closeBtn =win.add("button", undefined, "CLOSE");

closeBtn.onClick = function () {
if (textInput.text == "")
alert("ALERT !!!\nEMPTY EDITTEXT?");
else {
win.hide();
}
}

win.show();

Yes, this solution works. Thank you for providing the sample. Once the alert dialog is closed can the scriptUI insert the original textfiled value TEXT in the empty field?

[Geppetto Luis]

that's fine.

var regExp = new RegExp();
win = new Window("dialog", "TEST",undefined);

var textInput =win.add("edittext", undefined, "TEXT");
textInput.characters = 20;
textInput.active = true;

closeBtn =win.add("button", undefined, "CLOSE");

closeBtn.onClick = function () {
if (textInput.text == "")
alert("ALERT !!!\nEMPTY EDITTEXT?");
else {
win.hide();
}
 textInput.text = "TEXT";
}

win.show();

Thank you much, that works. Can the filed focus return to highlight the TEXT in blue after the validation? 

I placed textInput.active = "true" below textInput.text = "TEXT" in the onClick function. But the filed focus does not dispaly.
