気象データに関するいくつかの JSON ファイルをマージしようとしていますが、それを行う最善の方法を見つけようとしています。JSONオブジェクトを連結するだけの投稿や、同じキーの場合に2番目のオブジェクトが最初のオブジェクトを上書きするなどの他のいくつかの投稿を見つけましたが、キーでそれらをマージするものは何もありません。

以下は、私が取り組んでいるものと私が望む出力のサンプルです。これに関する提案は素晴らしいでしょう！

Try this:

function mergeJson(target) {
    for (var argi = 1; argi < arguments.length; argi++) {
        var source = arguments[argi];
        for (var key in source) {
            if (!(key in target)) {
                target[key] = [];
            }
            for (var i = 0; i < source[key].length; i++) {
                target[key].push(source[key][i]);
            }
        }
    }
    return target;
}

DEMO: http://jsfiddle.net/4nfWp/1/

And you call it like: mergeJson({}, object1, object2, object3); (with any number of arguments past the 1st)

In the demo, the actual call is at the bottom of the Javascript because I need the "JSON" to be defined first, and they're long.

UPDATE:

If using underscorejs, you can use something like:

var finalJson = {};
_.each(_.keys(json0,json1), function(key) {
    finalJson[key] = _.flatten(_.zip(json0[key], json1[key]));
});
console.log(finalJson);

DEMO: http://jsfiddle.net/4nfWp/4/

Credit goes to @djKianoosh for figuring that out :)
