google drive javascript api gapi.client.drive.files undefined

Question

The JavaScript example to list files of Google Drive uses gapi.client.drive.files.list(). When trying to use this method I get the error \"Cannot read property

Answer 1

If it works fine after writing gapi.client.load('drive', 'v2', callback), then all good. In my case it does not work so I wrote below code.

gapi.load('client', function () {
                gapi.client.load('drive', 'v2', function () {
                    var file = gapi.client.drive.files.get({ 'fileId': fileId });
                    file.execute(function (resp) {
                        //Write you code with resp variable
                    });

                });
            });
