文字列の特殊文字を確認してください

文字列に！@＃$％^＆*。、<>/\ '";：？のような特殊文字が含まれているかどうかを確認し、文字列に少なくとも1つの文字が含まれている場合はtrueを返します。

私は次の正規表現、スクリプトで試しました：

var format = /^[!@#$%^&*()_+\-=\[\]{};':"\\|,.<>\/?]*$/;

if( string.match(format) ){
  return true;
}else{
  return false;
}

文字列に特殊文字のみが含まれる場合はtrueを返しますが、文字列に英数字（！example1、.example2）などの何かが含まれる場合はfalseを返します。

RegExp .test()関数を使用してパターン一致をチェックすることをお勧めします。変更する必要があるのは、正規表現の行アンカーの開始/終了（および*量指定子も不要）を削除することだけです。

var format = /[ !@#$%^&*()_+\-=\[\]{};':"\\|,.<>\/?]/;
//            ^                                    ^   
document.write(format.test("My@string-with(some%text)") + "<br/>");
document.write(format.test("My string with spaces") + "<br/>");
document.write(format.test("MyStringContainingNoSpecialChars"));

アンカー（^文字列/行の開始、$ end od文字列/行、および\bワード境界など）は、文字列内の特定の場所での一致を制限できます。 ^を使用する場合、正規表現エンジンは次のサブパターンが文字列の先頭に表示されるかどうかを確認します（または/m修飾子が正規表現で宣言されている場合は行）。 $の場合と同じ：前のサブパターンは、文字列の最後で一致する必要があります。

あなたの場合、文字列内のセットanywhereからの特殊文字の存在を確認したいです。たとえ1つだけであっても、falseを返します。したがって、アンカーと量指定子*を削除する必要があります。 *量指定子は空の文字列と一致するため、少なくとも1つの特殊文字の存在を実際に確認するために削除する必要があります（実際には、確認する量指定子なしでexactly 1回、同じ{1}制限数量詞を使用しているかのように）。

正規表現は^と$を使用するため、文字列全体と一致するように試みます。結果としてブール値のみが必要な場合は、testの代わりにmatchを使用します。

var format = /[!@#$%^&*()_+\-=\[\]{};':"\\|,.<>\/?]+/;

if(format.test(string)){
  return true;
} else {
  return false;
}

代わりに、英数字を否定一致させる方が簡単ではないでしょうか？

return string.match(/^[^a-zA-Z0-9]+$/) ? true : false;

正規表現から文字^（文字列の先頭）および$（文字列の末尾）を削除します。
