まず、pyppeteer で直接 page.querySelectorAll() を使用してすべての要素を直接取得することはできない可能性があります。
str(await (await element_songer_name.getProperty("title")).jsonValue())
データ値を取得します。主な理由は #document の問題である可能性があります。
したがって、この問題が発生した場合は、すぐに js で試してはいけません。次のコードを使用して解決できます。
frames = page.frames
# print(frames)
iframe = frames[1] # 第一个iframe frames[0]相当于是page.content() 整个页面的html 想要访问iframe的就要frames[0] [1]
# await iframe.click("#content-operation > a.u-btn2.u-btn2-2.u-btni-addply.f-fl")
elements_song_names = await iframe.querySelectorAll("td:nth-child(2) > div > div > div > span > a > b")
elements_songer_names = await iframe.querySelectorAll("td:nth-child(4) > div > span")次に、js を使用してクロールするだけであれば、不可能ではありません。実際、非常に便利です。直接クロールできます。#document は問題ありませんが、適切なデータを取得する方法を考える必要があります。 「コピー」: 配列を直接印刷すると、
次のようなデータ形式が得られます: レプリケーションと再利用には適していません:
このとき、印刷方法を変更する必要がありますが、まず、1つ目の方法：
console.table(song_names)で取得するデータ形式は以下の通りです。
コピーした方が良いですし、一重引用符もあるので、再利用のためにコードに組み込む方が良いです。最良の方法は、
console.log(JSON.stringify(song_names)) を使用して、次と同じ結果を得ることができるようにすることです。 Python は次のように配列を出力します。
さらにエクスペリエンスが大幅に向上したコピー ボタンもあります。
結果のデータ形式は次のとおりです。

ただし、大規模なデータ クローラーの場合は、依然としてコンパイラーで実行することを好みます (js スクリプト プロジェクトを作成し、それを実行する前にブラウザー スクリプトまたはプラグインにパッケージ化した後であっても)。
