JavaScriptでwindowを閉じるやつ

More than 5 years have passed since last update.

JavaScriptで現在開いているタブを閉じようと思って、

window.close();

とか叩いても、セキュリティポリシーとかで大体禁止されているので閉じられない。

そんなときは、

window.open('about:blank','_self').close();

とやると閉じることが出来るみたい。

一回自分自身に対して空タブを開くことでjsの操作対象にして、その上でclose()を実行している感じ。

ちなみにFireFoxはこれでもダメで、空タブが残ってしまうので諦めてください。


なお、

window.open('','_self').close();

こちらでもいけますが、これだとFireFoxで本当に何も起こらないので、そういう挙動のほうがいいならこちらがいいかもしれません。
