The regular expression in JavaScript utilizes the \xxx expression to manipulate octal numbers represented by Latin characters. This enables us to incorporate octal numbers when testing, searching, or matching Latin characters.
Syntax
- Syntax without modifiers
The syntax is used for manipulating the Latin character of the octal numeral system.
/\xxx/
- Syntax with modifiers
The syntax functions to manipulate octal numbers using specified modifiers.
/\xxx/g
Supported Browsers
The javascript \xxx regex Metacharacter supports the following browsers:
- Google Chrome browser
- Safari browser
- Mozilla Firefox
- Opera browser
- Internet Explorer browser
Examples
Below are instances that demonstrate how to match, search, test, and manipulate Latin characters using regular expressions in JavaScript.
Example1: use the search method in the \xxx regex
In this illustration, octal values are represented by Latin characters using regular expressions in JavaScript. The test method is utilized to obtain the Boolean result 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('Example 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> Example website to Learn : "+octal_regex3
}
</script>
</body>
</html>
Output:
The result displays the accessibility of the octal input sequence.
Example2: use the search method in the \xxx regex without a modifier
The provided illustration is specifically applicable to regular expressions for strings without any modifier.
<!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/;
var input_val1 = 'Hello Coder';
var input_val2 = 'You Learn JavaScript language';
var input_val3 = 'Example 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> Example website to Learn : "+octal_regex3
}
</script>
</body>
</html>
Output:
The result displays the Latin representation of the octal input string.
An example of utilizing the exec method involves applying it within the \xxx regular expression alongside a modifier.
The provided illustration is specifically designed to function with regular expressions applied to strings with a global modifier. It is tailored to search through the complete content of the input string.
<!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.exec('Hello Coder');
var octal_regex2 = octal_pattern.exec('You Learn JavaScript language');
var octal_regex3 = octal_pattern.exec('Example 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> Example website to Learn : "+octal_regex3
}
</script>
</body>
</html>
Output:
The result displays the Latin representation of the octal input string.
Example4: use the match method in the \xxx regex
The illustration compares the octal representation of the string with the global flag enabled.
<!DOCTYPE html>
<html>
<head>
<title>
JavaScript RegExp \xxx (octal) Metacharacter
</title>
</head>
<body>
<h3>

<script>
function octal_display() {
let octal_pattern = /\112/g;
var input_val1 = 'Hello Coder';
var input_val2 = 'You Learn JavaScript language C# Tutorial';
var input_val3 = 'Example 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");

}
</script>
</body>
</html>
Output:
The result displays the provided values expressed in Latin and formatted in octal.
Conclusion
The user-provided values are transformed and shown in Latin characters to represent octal values. Octal values are structured in groups of four characters and validated using the \u regular expression pattern.
