arrays - 新しい項目を json 配列に追加 (プッシュ) する方法

Question

次のように同じ配列を取得したい：

var data = 
[
{"date":"20111001","Happy":"63.4","Sad":"62.7","Angry":"72.2"},    
{"date":"20111002","Happy":"67.4","Sad":"61.7","Angry":"52.2"},   
{"date":"20111003","Happy":"60.4","Sad":"84.7","Angry":"44.2"}
];

2 つのリストがある場合: リスト アイテム

var items=["date","Happy","Sad","Angry"]; 

および値の配列:

    var values=[
            ["20111002","67.4","61.7","52.2"],
            ["20111003","60.4","84.7","44.2"],
        ];

同じ最初の例を得るために、配列に結合する方法:項目と値?
