こんにちは、ばかげた質問かもしれませんが、たとえばこれから印刷するにはどうすればよいですか

オブジェクト内のオブジェクトへのアクセスに問題があります。情報を教えてください。

私は次のようなことをしたかった:

 alert(text.responseData['results'])

このtextjson オブジェクトを chrome のコンソールに貼り付けます。textそして、変数にアクセスしてみてください。オートコンプリートされ、変数内のオブジェクトへのパスを見つけるのに役立ちます。それが私がjsonオブジェクトに対して行うことです。変数については、startこのコードを試してください。

var pages = text.responseData.cursor.pages;
for(var i=0; i < pages.length; i++){
   console.log(pages[i].start)
}
