ESCAPING CHARACTERS IN JAVASCRIPT

Certain characters after a backlash \ have a special effect in the javascript code. This is referred to as the escape sequence.

Some of these characters are:

\n

Characters after it start on a new line.

Example:

var string="Go on, make \n my day";

alert(string);

The above outputs:

Go on, make
my day

\t

Horizontal tab space immediately after.

Example:

var string="Go on, make\t my day";

alert(string);

The above outputs:

Go on, make       my day

\r

Carriage return immediately after.

Example:

var string="Go on, make\r my day";

alert(string);

The above outputs:

Go on, make
my day

\'

Single quote. Useful in single quoted strings without causing the string to terminate prematurely.

Example:

var string='Go on, \'make my\' day';

alert(string);

The above outputs:

Go on, 'make my' day

\"

Double quote. Useful in double quoted strings without causing the string to terminate prematurely.

Example:

var string="Go on, \"make my\" day";

alert(string);

The above outputs:

Go on, "make my" day

\\

Single backslash. Allows you to literally insert a backslash character.

Example:

var string="Go on, \\make my day";

alert(string);

The above outputs:

Go on, \make my day

Other special characters:

\f - form feed
\b - backspace
