[javascript]URLを取得する正規表現

今後も何かで使いそうなのでメモ。
http://example.com?keyword=hogehoge&limit=25
のようなクエリパラメータにも対応してます。

  • 英字のみのURL
/https?:\/\/[-_.!~*\'()a-zA-Z0-9;\/?:\@&=+\$,%#]+/g
  • 日本語を含むURL
/https?:\/\/[-_.!~*\'()a-zA-Z0-9;\/?:\@&=+\$,%#\u3000-\u30FE\u4E00-\u9FA0\uFF01-\uFFE3]+/g

でいける。ちなみにimgタグなどの画像のURLを取得したい場合は

/(src=)["|'](.*?)["|']+/g

でsrcの部分だけ先に取得して上記のURLの正規表現をとってこればいけるはず。
