I'm defining a class in javascript as
Class = (function() {
var privateFunction = function() { return "private"; }
return { publicFunction: function() { return privateFunction("public"); } };
)();
Here user can access Class.publicFunction, but not Class.privateFunction.
Now I want to provide the user an interface to extend this Class. So I added a public function extend.
Class = (function() {
var privateFunction = function() { return "private"; }
return {
publicFunction: function() { return privateFunction("public"); }
extend: function(source) {
dest=this;
for(var prop in source)dest[prop] = source[prop]
}
};
)();
My aim was to use the extend attribute as follows
Class.extend({
someFunc: function() { return privateFunction("hooray"); }
});
and access it as
Class.someFunc()
The problem I face is the call to the privateFunction() in the extended function someFunc is not available for it. I can understand that it is the problem of the scope, but, is there anyway to solve my need.
