Re: [問題] javascript 的 private 屬性

[BBSealion (海獅)]

Private members are made by the constructor. Ordinary vars and parameters of
the constructor becomes the private members.

    function Container(param) {
        this.member = param;
        var secret = 3;
        var that = this;
    }

This constructor makes three private instance variables: param, secret, and
that. They are attached to the object, but they are not accessible to the
outside, nor are they accessible to the object's own public methods.

我知道private的用意就是保護變數不被亂動
但另一個他該有的功能是: 在自己的method中能被使用
不然我為了自己要用他就得開getter給他，如此變成您說的無意義了

我想js的邏輯跟C應該不太一樣，所以有點困惑中
但應該有個對應的做法

推 lausai:大師的作法符合的嚴格的物件導向要求 但卻犧牲了效能跟簡潔
→ lausai:所以我覺得折衷的底線宣告法 應該是現在最好的方式 還有一
→ lausai:般提到 getter/setter 都會想到是 1.public 2.called from
→ lausai:outside client 所以你提到 getter/setter 會讓人有點誤會
→ lausai:因為網頁中你所謂的 setter/getter 是內部使用並不開放
→ lausai:大師也沒有使用getter/setter 而是以private method 稱呼它
→ BBSealion:恩了解~ 加底線真的是個很輕鬆的解法
