ここでは、テキストからすべての句読点を削除しようとしています。しかし、私のコードでは出力が得られません。Web スクリプト言語に関する知識が不足しているため、解決策が見つかりません。テキストから句読点を削除するにはどうすればよいですか? ここで何が間違っていますか？

アップデート

Rahul の回答によると、次のようにコードを編集しましたが、残念ながらまだうまくいきません。最初の句読点だけでなく、テキスト全体からすべての句読点を削除したい。

あなたはこのように試すことができるかもしれません:-

var s = "Your%^%*^%^&*^% string '"+"'which*^&^&( consists of punctuation";
var st = s.replace(/["']/g, "")
var newstring= st.replace(/[\.,-\/#!$%\^&\*;:{}=\-_`"~()]/g,"");
var finalString = newstring.replace(/\s{2,}/g," ");
alert(finalString);

上記のコードは、文字列のすべての句読点を置き換えますs

上記のコードは正常に動作します。JSFIDDLEを確認してください。
