How to remove title(instance says) from the confirm box

[Tabassum Sulta1]

How can we remove the highlighted message from the confirm box?

I have used confirm function for the pop up but want remove the instance says(highlighted) message here attached in screenshot.

function Test(){

var ans = confirm("This is the confirmation msg click ok");
if (ans == false) {

return false();

        }

}

The window.confirm() method functionality is a native modal dialog so it'll depend on the browser. As you can see, firefox renders the confirm modal differently:

You'll likely need to go down the route of a custom GlideDialogModal.

Does using sp model will work here, in UI Action as I don't want to use UI pages?

Sadly not, native ui required Jelly

You can create a Confirmation Modal:

var dialog = new GlideModal('glide_modal_confirm', true, 300);
dialog.setTitle(new GwtMessage().getMessage('Confirmation'));
dialog.setPreference('body', new GwtMessage().format("Your message"));
dialog.setPreference('focusTrap', true);
dialog.setPreference('onPromptComplete', doComplete);
dialog.setPreference('onPromptCancel', doCancel);
dialog.render();

function doComplete() {
    callback(true);
}

function doCancel() {
    callback(false);
}

No need to create a UI Page.
