javascript - JS サンプル コードでシェープファイルを追加する

Question

フォルダからマップにシェープファイルを追加したい。私はJSサンプルコードを使用しましたが、機能しません.応答でエラーが発生します.featurecollection. リクエスト ブロックに入らないので、esri リクエストに変更しますが、コードが機能しません

              <!-- fileName = arr[arr.length - 1]; -->
            <!-- } -->
            if (fileName.indexOf(".zip") !== -1) {//is file a zip - if not notify user
