JavaScript provides special characters that allow you to include in strings some characters you can't type directly. Each of these characters begins with a backslash. The backslash is an escape character you use to inform the JavaScript interpreter that the next character is special.
Escape Sequence |
Character |
\b |
Backspace |
\f |
Form feed |
\n |
Line feed ( newline ) |
\r |
Carriage return |
\t |
Horizontal tab ( Ctrl-I ) |
\' |
Single quotation mark |
\" |
Double quotation mark |
\\ |
Backslash |
Notice that because the backslash itself is used as the escape character, you cannot directly type one in your script. If you want to write a backslash, you must type two of them together ( \\ ).
aString = "The class of \'97";
aPath = "c:\\myweb\\myhome.aspx";
You can use these escape sequences to control formatting of text inside <PRE> and <XMP> tags and, to some extent, inside alert, prompt, and confirm message boxes.
