HTML DOM Bdo Object

Last Updated : 15 Jun, 2023

The DOM Bdo Object is used to represent the HTML <Bdo> element. The Bidirectional element is accessed by getElementById().

Properties: It has a dir attribute which is used to set or return the text direction of an element.

Syntax:

document.getElementById("GFG");

Where “GFG” is the ID assigned to the “bdo” tag.

Example 1: In this example, we will use DOM Bdo Object.

HTML

<!DOCTYPE html>
<html>
   
<head>
    <style>
        h1 {
            color: green;
        }
        h2 {
            font-size: 35px;
        }
    </style>
</head>
   
<body>
    <h1>GeeksForGeeks</h1>
    <h2>DOM Bdo Object</h2>
    <bdo id="GFG" dir="rtl">
        A Computer science portal for geeks
    </bdo>
    <br>
    <button onclick="myGeeks()">Submit</button>
    <p id="sudo"></p>
   
    <script>
        function myGeeks() {
            let w = document.getElementById("GFG");
            if (w.dir === "rtl") {
                document.getElementById("sudo").innerHTML =
                    "right to left text direction";
            } else {
                document.getElementById("sudo").innerHTML =
                    " left to right text direction.";
            }
        }
    </script>
</body>
   
</html>

Output:

            let f = document.createTextNode("GeeksForGeeks.");
            g.setAttribute("dir", "rtl");
