var Foo = (function () {
var cls = function () {
this.prototype = {
sayhi: function () {
alert('hi');
}
};
};
cls.staticMethod = function () {};
return cls;
})();
var f = new Foo();
Why can't i access my sayhi method? Doesn't this refer to the cls variable?
You are attempting to set the prototype property on every instance of cls. What you actually want to do is set the prototype property of cls itself:
var Foo = (function () {
var cls = function () {}; // Constructor function
cls.prototype = { // Prototype of constructor is inherited by instances
sayhi: function () {
alert('hi');
}
};
return cls;
})();
cls {}, cls {sayhi: function}, but aren't both using the same prototype and should therefore share the sayhi function?
cls. Setting the prototype inside the constructor will cause all sorts of problems. For example, try window.f instanceof foo in your example - it will return false.
