JavaScript Special Characters

Previous

Next

Im Javascript kannst du Special Characters einer Textfolge hinzuf�gen, indem Sie das Gegenschr�gstrichzeichen verwenden.

Insert Special Characters

Der Gegenschr�gstrich (\) wird verwendet, um Apostrophe, neue Linien, Anf�hrungsstriche und andere Special Characters in eine Textfolge einzusetzen.

Da der Gegenschr�gstrich der Entweichenbuchstabe ist, den Gegenschr�gstrich, selbst einsetzen, den du ihn verdoppeln mu�t (\ \).

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)

Look at the following JavaScript code:

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

Im Java Index wird eine Zeichenkette begonnen und mit irgendeinem einfache oder doppelte Anf�hrungsstriche gestoppt. Dies hei�t, da� die Zeichenkette oben zu gehackt wird.

Um dieses Problem zu l�sen, mu�t du einen Gegenschr�gstrich (\) vor jeden Anf�hrungszeichen in �Viking� legen. Dieses macht jede Anf�hrungszeichen zu einen Zeichenkettedruckfehler:

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

Javas Index gibt jetzt die korrekte Textfolge aus: Wir sind das sogenannte �Vikings� vom Norden.

Ist hier ein anderes Beispiel:

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

Output

You & me are singing!
