Answer You can change the CSS class of a textbox (or any other HTML element) using JavaScript by manipulating the classList property. Here's an example:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<style>
.originalClass {
/* Your original styles here */
border: 1px solid #ccc;
padding: 5px;
}
.newClass {
/* Your new styles here */
border: 2px solid #ff0000; /* Red border as an example */
padding: 10px;
}
</style>
<title>Change CSS Class Example</title>
</head>
<body>
<input type="text" id="myTextbox" class="originalClass">
<script>
// Function to change the class
function changeClass() {
var textbox = document.getElementById("myTextbox");
// Remove the current class
textbox.classList.remove("originalClass");
// Add the new class
textbox.classList.add("newClass");
}
// Call the function to change the class (you can trigger this in response to an event)
changeClass();
</script>
</body>
</html>
In this example, we have an input textbox with an initial class of "originalClass." The JavaScript function changeClass is defined to remove the original class and add a new class ("newClass"). You can trigger this function in response to an event such as a button click, form submission, or any other user action.
Make sure to replace the styles and class names with your own as needed.
