The code at the end works but I have a question.
When I have this code construction with prototype I can call the getFoo in
this way var poo = f.getFoo(); // "bar"
P.prototype.getFoo = function ()
{
return this.foo;
};
I mean if I add this piece of code into the class definition I can call the
getFoo in this way var poo = f.getFoo(); // "bar"
this.getFoo = function ()
{
return this.foo;
};
So as a summary can somebody explain what is the advantage to use a
prototype in this exemple?
Here is the complete code
********************
<script type="text/javascript">
function P(foo) //Here is the class definition
{
this.foo = foo;
// implicit return av "this" i den fall då P anropas som
konstruktor
}
P.prototype.getFoo = function ()
{
return this.foo;
};
var f = new P("bar");
var g = new P("baz");
var poo = f.getFoo(); // "bar"
g.getFoo(); // "baz"
</script>
