Soukromé modely
Do modelu můžete přidat svá vlastní soukromá data.
Tento příklad naznačuje omezení dat:
Příklad
"restrictions" : {
"fname" : {"maxlength": 40},
"price" : {"max": 999,"min": 100}
}
Data modelu mohou používat serverové aplikace a váš řadič AppML.
Tento příklad používá data modelu k ověření vstupu:
Příklad
function myController($appml) {
if ($appml.message == "submit") {
var price = document.getElementById("price").value;
if (price < $appml.model.restrictions.price.min) {
$appml.displayError(15, "Price
too low!");
return;
}
}
