Display alert message only once

You must Login before you can answer or comment on any questions.

I have a button, on click an alert appears and a new win will open.

button1.addEventListener('click', function(){
    var win1 = Ti.UI.createWindow({
        url:'some.js',
  })
 
  {
    alert("Hello! You will only se me once :)");
}; 
    win1.open();
});

Is it possible to display this alert only once (it will never appear again)?

you can use boolean property to set this like

Ti.App.appear = true;
Ti.App.appear = false;
 
button1.addEventListener('click', function(){
    var win1 = Ti.UI.createWindow({
        url:'some.js',
  });
 
 if(Ti.App.appear == false){ 
    alert("Hello! You will only se me once :)");
    Ti.App.appear = true;
}
    win1.open();
});
