The RegExp \v Metacharacter in JavaScript is used to find the vertical tab character. If it is found it returns the position else it returns -1.

Syntax:

/\v/ 

or

new RegExp("\\v")

Example 1: This example searches for the vertical tab character in the string.




<!DOCTYPE html>
<html>
  
<head>
    <title>
        JavaScript RegExp \v Metacharacter
    </title>
</head>
  
<body style="text-align:center">
      
    <h1 style="color:green">
        GeeksforGeeks
    </h1>
      
    <h2>RegExp \v Metacharacter</h2>
      
    <p>Input String: GeeksforGeeks@_123_$</p>
      
    <button onclick="geek()">
        Click it!
    </button>
      
    <p id="app"></p>
      
    <script>
        function geek() {
            var str1 = "GeeksforGeeks@_123_$";
            var regex4 = /\v/;
            var match4 = str1.search(regex4);
            if(match4 == -1) {         
                document.getElementById("app").innerHTML
                = "No vertical tab character present. ";
            } else {
                document.getElementById("app").innerHTML = 
                "Index of vertical tab character: " + match4;
            }
        }
    </script>
</body>
  
</html>                    

Output:
