JSONを楽にJavaScriptObjectへ変換する

Posted at

JSONファイルを読み取って, JavaScript Objectへ変換する関数を実装しようとしました.
行き詰まっていたところ, teratailで質問をするとすぐに回答が付きました. 便利な世の中になりましたね.

以下ソースコードです. jQuery依存コードです.

const readjson = path => {
    let jsondata;
    $.ajaxSetup({ async: false }); // Ajax通信を同期通信にする
    $.getJSON(path, data => {
        jsondata = data;
    })
    $.ajaxSetup({ async: true }); // Ajax通信を非同期通信に戻す
    return jsondata;
};

使うときは, [const/let] [変数名] = readjson([jsonのパス])を記述します.
