JavaScript Special Characters
In JavaScript you can add special characters to a text string by using the backslash sign.
Insert Special Characters
The backslash (\) is used to insert apostrophes, new lines, quotes, and other special characters into a text string.
Look at the following JavaScript code:
var txt="We are the so-called "Vikings" from the north.";
document.write(txt); |
In JavaScript, a string is started and stopped with either single or double quotes. This means that the string above will be chopped to: We are the so-called
To solve this problem, you must place a backslash (\) before each double quote in "Viking". This turns each double quote into a string literal:
var txt="We are the so-called \"Vikings\" from the north.";
document.write(txt); |
JavaScript will now output the proper text string: We are the so-called "Vikings" from the north.
Here is another example:
| document.write ("You \& I are singing!"); |
The example above will produce the following output:
