To set the text direction, use the direction property with JavaScript. Set rtl for right-to-left or ltr for left-to-right text direction.
Example
You can try to run the following code to set the text direction with JavaScript −
<!DOCTYPE html>
<html>
<body>
<h1 id="myID">Heading 1</h1>
<p>Click below to set the direction of heading to Left-to-right</p>
<button type="button" onclick="display()">Click to change the direction</button>
<script>
function display() {
document.getElementById("myID").style.direction = "rtl";
}
</script>
</body>
</html>
