Auto update div content while typing in textarea using jQuery

Topic: JavaScript / jQueryPrev|Next

Answer: Use the jQuery keyup() method

You can use the jQuery keyup() method in combination with the val() and text() method to simultaneously update the <div> element content, while user writing the text in a <textarea>.

Let's try out the following example to understand how it basically works:

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>jQuery Auto Update Div with Content from Textarea</title>
<style>
    .output{
        padding: 10px;
        min-height: 50px;
        border: 1px solid #e4e4e4;
    }
</style>
<script src="https://code.jquery.com/jquery-3.5.1.min.js"></script>
<script>
$(document).ready(function(){
    $("#myTextarea").keyup(function(){
        // Getting the current value of textarea
        var currentText = $(this).val();
        
        // Setting the Div content
        $(".output").text(currentText);
    });
});
</script>
</head>
<body>
    <form>
        <textarea id="myTextarea" rows="5" cols="60" placeholder="Type something here..."></textarea>
    </form>
    <div class="output"></div>
</body>
</html>
