search() - FUNCTION

search() Function

The search() Function is used to find a substring from the String. It gives us the position of the substring.

Example :

<html>
<body>  
<script>

	var x = "Hello Beautiful World"
	var y = x.search("Beautiful")
	document.write("The substring is located at the position ",y)
    
</script>      
</body>
</html>

Output :

The substring is located at the position 6

In the above code, we have declared a String Hello Beautiful World and assigned it to a variable x.

x = "Hello Beautiful World"

And we would be searching the substring Beautiful, from the String, Hello Beautiful World.

So, we have used the search() Function to find the substring Beautiful.

y = x.search("Beautiful")

And what search() Function does is, goes to the String Hello Beautiful World and searches for the position of the substring Beautiful.

And finds the substring Beautiful in the 6th position. And the position (i.e. 6) is stored in variable y.

And thus prints the position.

document.write("The substring is located at the position ",y)

Output :

The substring is located at the position 6
