Question

I have following code

function Model(onChanged) {
    this.array = new Array();
    this.onChanged = onChanged;
}
Model.prototype.push = function(val) {
    this.array.push(val);
    if (typeof(this.onChanged) !== 'undefined') {
        this.onChanged();
    }
}

console.log(JSON.stringify(Model.prototype));
console.log(JSON.stringify(Model.prototype.push));

And this gives me

{}
undefined

I’ve looked through some qml js code and there were same classes definitions so I can’t get why this doesn’t work for me. And autocomplete says that existing classes like Object, array, etc have prototype property. I tried to subclass them but got the same result.

Try

console.log(Model.prototype);
console.log(Model.prototype.push);

JSON does not handle function or class definitions and therefore shows empty results.
