Caractères spéciaux de Javascript

Previous

Dans le Javascript vous pouvez ajouter les caractères spéciaux à une corde des textes en employant le signe d'antislash.

Insérer les caractères spéciaux

L'antislash (\) est employé pour insérer des apostrophes, de nouvelles lignes, des citations, et d'autres caractères spéciaux dans une corde des textes.

Puisque l'antislash est le caractère d'évasion, pour insérer l'antislash lui-même que vous devez le doubler (\ \).

Escape Sequence	Character
\'	Single quotation mark
\"	Double quotation mark
\\	Backslash
\b	Backspace
\f	Form feed
\n	New line
\r	Carriage return
\t	Horizontal tab
\ddd	Octal sequence (3 digits: ddd)
\xdd	Hexadecimal sequence (2 digits: dd)
\udddd	Unicode sequence (4 hex digits: dddd)

Regarder le code suivant de Javascript :

var txt="We are the so-called "Vikings" from the north."
document.write(txt)

En manuscrit de Java, une corde est commencée et arrêtée par l'un ou l'autre des citations simples ou doubles. Ceci signifie que la corde ci-dessus sera coupée à.

Pour résoudre ce problème, vous devez placer un antislash (\) avant chaque double citation dans « Viking ». Ceci transforme chaque double citation en coquille de corde :

var txt="We are the so-called \"Vikings\" from the north."
document.write(txt)

Le manuscrit de Javas produira maintenant la corde appropriée des textes : Nous sommes prétendu « Vikings » du nord.

Voici un autre exemple :

document.write ("You \& me are singing!")

Rendement

Toi et moi chantez !
