Search method in javascript

The JavaScript search() method searches a string for a specified value, or regular expression, and returns the position of the match.
But -1  will be returned if no match is found.

Syntax:

string.search(searchvalue)
where,     searchvalue = Required. The value, or regular expression, to search for.

Example:

var str=”The JavaScript SEARCH() method searches a string.This JavaScript search() method return position number”
var num=str.search(“search”);
alert(num);         // OUTPUT: 31 cause search function is case sensitive
num=str.search(/search/i);
alert(num);       // OUTPUT: 15
