In JavaScript, Special characters can be added to a text string by using the backslash sign. For example we want to display following text in JavaScript code.
var txt="This "This is a "big" Apple.";
In JavaScript, a string is started and stopped with either single or double quotes. This means that the string above will be chopped to:
This is a
We must place a backslash (\) before each double quote in "big" to solve this problem. This result string will look like this :
var txt="This "This is a \"big\" Apple.";
After executing in browser, it will display string as :
This is a "big" Apple.
There are many other special characters that can be added to a text string with the backslash sign, these are :
\' ( single quote )
\" ( double quote )
\\ ( backslash )
\n ( new line )
\r ( carriage return )
\t ( tab )
\b ( backspace)
\f ( form feed )
