Hi, you can integrate this dialog function in github of f7,
and if it is possible for Alert and Confirm methods, it will be more appreciated, Thanks

//Checkbox to not show again

app.on(‘dialogOpen’, function (event) {

var tipo = event.params.DoNotShowAgain || false;

if (!tipo || event.app.params.dialog.DoNotShowAgain == false) return;

var hashCode = function(txt) {
  var hash = 0, i, chr;
  if (txt.length === 0) return hash;
  for (i = 0; i < txt.length; i++) {
    chr   = txt.charCodeAt(i);
    hash  = ((hash << 5) - hash) + chr;
    hash |= 0; // Convert to 32bit integer
  }
  return hash;
}

event.hash = event.params.id || hashCode((event.params.title || "") + (event.params.text || ""));

event.hashes = JSON.parse(localStorage.getItem("DoNotShowAgain") || "[]");

if (event.hashes.indexOf(event.hash) != -1) {
    event.close();
    return;
}

var msg = '<br /><br /><label class="checkbox"><input class="DoNotShowAgain" type="checkbox"><i class="icon-checkbox"></i></label> ';

msg += tipo != true ? tipo : event.app.params.dialog.DoNotShowAgain || 'No volver a mostrar este mensaje.';

event.setText((event.params.text || "") + msg);

});

app.on(‘dialogClosed’, function (event) {
var el = event.el.getElementsByClassName(“DoNotShowAgain”) || [0];
if (el[0] && el[0].checked) {
event.hashes.push(event.hash);
localStorage.setItem(“DoNotShowAgain”, JSON.stringify(event.hashes));
}
});
