URLからファイル名を取得する正規表現

More than 5 years have passed since last update.

これは便利。

var url = window.location.href;

// 拡張子付きで
var filename_ex = url.match(".+/(.+?)([\?#;].*)?$")[1];
// 拡張子無しで
var filename = url.match(".+/(.+?)\.[a-z]+([\?#;].*)?$")[1];

参考URLのスクリプトでは、QueryStringやhashがあった場合、ファイル名が正常に取得出来ないの、修正しました。kawazさんのご指摘ありがとうございます!
