  • jquery:JavaScriptに基づいて作成されたライブラリ
  • jqueryは$(セレクタ)と同じ式を使用して、必要なHTMLのDOM要素
    • を検索します.
  • JSON:インターネットで資料を交換する際に使う文法
  • request:url=要求サーバからこのアドレスの情報を送信する->サーバは応答によって情報を提供する.このとき、ブラウザはajaxを受信します(画面をリフレッシュしません)
  • api:ブラウザとサーバのウィンドウ
  • GETとPOSTはrequest形式
    • を採用
  • bs 4によるWebスクロール(必要な情報を取得)
  • meta tag/
    bs 4を使用してmetaタグを記述する場合は、既存のスクリプトフォーマットとは異なる必要があります(alonememo app.pyを参照).
