I'm kinda new to OOJS so please bear with me on this. I'm trying to get a setup like the following:
Item
name = "no name"
description = "no description"
someVar = "no var"
Section
name = "Section A"
//Rest are inherited
deleted = false
So far I have:
function Item() {}
function Section() {}
$.extend(Item.prototype, {
name: "no name",
description: "no description"
}
Section.prototype = Item.prototype;
$.extend(this.Section.prototype, {
description: "A section",
swung: true,
swing: function() {
this.swung = false;
return this;
}
});
$.extend(this.Item.prototype, {
"date": "x"
});
$.extend(this.Section.prototype, {
"someVar": "someValue"
});
If I create a new Section, I get:
Section {
name: "no name",
description: "A section",
swung: true,
swing: function,
date: "x",
someVar: "someValue"
}
If I create a new Item, I get:
Item {
name: "no name",
description: "A section",
swung: true,
swing: function,
date: "x",
someVar: "someValue"
}
Obviously they're both the same, and the reason is that the prototype is the same instance. What I am trying to achieve is that all functions which inherit from Item pick up properties whenver they're added, and any changes to the value of a property on the Item prototype do not affect the property on Section if it has been overridden beforehand. Any changes to the Section prototype should not affect the Item prototype (as has obviously happened above) as there will be properties specific to Section. Does anyone know of any way to achieve this?
If I'm not being clear, please say so rather than downvoting me :). Thanks in advance.
