Found my answers here. Bottom line: toString/valueOf can only return primitive types. So here the lack of native getters in javascript shows, I suppose.
I would like to use the following simple function in an elementwrapper:
function ElGetter(id){
var id = id;
return {
set: function(nwid){id = nwid;},
toString: function(){return document.getElementById(id);},
valueOf: function(){return document.getElementById(id);}
};
}
var myEl = ElGetter('myId');
console.log(myEl.innerHTML); //=> undefined
But I can't get it to work. Is it a DOM/javascript restriction or am I missing something? Normally it works, as in:
function Tester(){
var x = 1;
return {
toString: function(){return x},
valueOf: function(){return x}
}
}
var myTest = Tester();
console.log(myTest); //=> 1
