JavaScript
For instance this code:
function stuff() {
this.onlyMethod = function () {
return something;
}
}
// some error is thrown
stuff().nonExistant();
Is there a way to do something like PHP's __call
as a fallback from inside the object?
function stuff() {
this.onlyMethod = function () {
return something;
}
this.__call__ = function (name, params) {
alert(name + " can't be called.");
}
}
// would then raise the alert "nonExistant can't be called".
stuff().nonExistant();
