We can use the IF statement to execute a group of one or
more script statements only, when a particular condition is met. Let’s create a
webpage, named IfStatement.html which shows the use of if statement.
#####Showing the code of the IfStatement.html file#####
<!DOCTYPE html>
<html>
<head>
<title>Using
if statement</title>
</head>
<body>
<h1>Using
the if statement in the script</h1>
<SCRIPT
type=”text/javascript”>
var
Number=45;
if((Number%2))
!=0)
{
document.write(Number +" is an
odd number");
}
document.write("<BR/>
Thank you");
</SCRIPT>
</body>
</html>
The script enclosed within the starting and the ending tags
of the body element has a variable named Number that is assigned a value 45.
The if statement has a condition which checks if the number is divisible by 2.
If the number is not divisible by 2 the statement within curly brackets are
executed and if the number is divisible by 2 the statement within the curly
bracket is ignored and the immediate statement is executed.
