The following example shows octal values in Latin characters using the regex in JavaScript. Here, the test method works to get the Boolean output of the value.

<!DOCTYPE html>
<html>
<head>
<title>
JavaScript RegExp \xxx (octal) Metacharacter
</title>
</head>
<body>
<h3>
JavaScript RegExp \xxx (octal) Metacharacter 
</h3>
<h4> The regex operates the function for the octal input values and shows in Latin characters.
</h4>
<div id = "regex_data"></div>
<button onclick = "octal_display();"> Click Here!</button>
<script>
function octal_display() {
let octal_pattern = /\112/g;
var octal_regex1 = octal_pattern.test('Hello Coder'); 
var octal_regex2 = octal_pattern.test('You Learn JavaScript language'); 
var octal_regex3 = octal_pattern.test('Javatpoint website to Learn'); 
var regex_ele = document.getElementById("regex_data");
regex_ele.innerHTML = " Hello Coder : "+octal_regex1+"<br> You Learn JavaScript language : "+octal_regex2+" <br> Javatpoint website to Learn : "+octal_regex3
}
</script>
</body>
</html>

Output:

The output shows the availability of the octal input string.

Example2: use the search method in the \xxx regex without a modifier

The following example works only for regular expressions for the string without any modifier.

<!DOCTYPE html>
<html>

</title>
</head>
<body>
<h3>

<div id = "regex_data"></div>
<button onclick = "octal_display();"> Click Here! </button>
<script>
function octal_display() {
let octal_pattern = /\112/;
var input_val1 = 'Hello Coder';
var input_val2 = 'You Learn JavaScript language';
var input_val3 = 'Javatpoint website to Learn';
var octal_regex1 = input_val1.search(octal_pattern); 
var octal_regex2 = input_val2.search(octal_pattern); 
var octal_regex3 = input_val3.search(octal_pattern); 
var regex_ele = document.getElementById("regex_data");
regex_ele.innerHTML = " Hello Coder : "+octal_regex1+"<br> You Learn JavaScript language : "+octal_regex2+" <br> Javatpoint website to Learn : "+octal_regex3
}
</script>
</body>
</html>

Output:

The output shows the Latin character of the octal input string.

<title>
JavaScript RegExp \xxx (octal) Metacharacter
</title>
</head>

<button onclick = "octal_display();"> Click Here!</button>
<script>
function octal_display() {
let octal_pattern = /\112/g;
var octal_regex1 = octal_pattern.exec('Hello Coder'); 
var octal_regex2 = octal_pattern.exec('You Learn JavaScript language'); 
var octal_regex3 = octal_pattern.exec('Javatpoint website to Learn'); 
var regex_ele = document.getElementById("regex_data");
regex_ele.innerHTML = " Hello Coder : "+octal_regex1+"<br> You Learn JavaScript language : "+octal_regex2+" <br> Javatpoint website to Learn : "+octal_regex3
}
</script>
</body>
</html>

Output:

The output shows the Latin character of the octal input string.

<script>
function octal_display() {
let octal_pattern = /\112/g;
var input_val1 = 'Hello Coder';
var input_val2 = 'You Learn JavaScript language Javatpoint';
var input_val3 = 'Javatpoint website to Learn';
var octal_regex1 = input_val1.match(octal_pattern); 
var octal_regex2 = input_val2.match(octal_pattern); 
var octal_regex3 = input_val3.match(octal_pattern); 
var regex_ele = document.getElementById("regex_data");
regex_ele.innerHTML = " Hello Coder : "+octal_regex1+"<br> You Learn JavaScript language : "+octal_regex2+" <br> Javatpoint website to Learn : "+octal_regex3
}
</script>
</body>
</html>

Output:
