JavaScriptでJSONファイルダウンロード

More than 5 years have passed since last update.

ブラウザだけでAPIを叩き、JSONファイルを取得する方法です。
d3.jsを使っているのは趣味なので、jQueryで取得してもただのJavaScriptで取得してもいいと思います。

コードを修正すれば、何度もAPIを叩きJSONを結合して最後にダウンロードするということもできます。
ただファイル名が必ずダウンロードとなるので、なんとかならないかな〜と思っています。

  //JSONファイルの読み込み
  d3.json(url,function(data){
     //JSONデータをURLに変換
    var href = "data:application/octet-stream," + encodeURIComponent(JSON.stringify(data));

    //URLを叩き、ダウンロード
    location.href = href;
    return true;
  });
