How to set focus on input field or textarea inside a Bootstrap modal on activation
Topic: Bootstrap / SassPrev|Next
Answer: Use the jQuery .focus() method
You can simply use the jQuery .focus() method to set the focus on the first input box or textarea inside the Bootstrap modal when it is loaded upon activation.
Let's try out the following example to understand how it basically works:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Set Focus on First Text Input inside Bootstrap Modal</title>
<link rel="stylesheet" href="css/bootstrap.min.css">
<script src="js/jquery-3.5.1.min.js"></script>
<script src="js/bootstrap.min.js"></script>
<script>
$(document).ready(function(){
$("#myModal").on('shown.bs.modal', function(){
$(this).find('#inputName').focus();
});
});
</script>
</head>
<body>
<!-- Button HTML (to Trigger Modal) -->
<a href="#myModal" class="btn btn-lg btn-primary" data-toggle="modal">Launch Demo Modal</a>
<!-- Modal HTML -->
<div id="myModal" class="modal fade">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title">Your Feedback</h5>
<button type="button" class="close" data-dismiss="modal">×</button>
</div>
<div class="modal-body">
<form>
<div class="form-group">
<label for="inputName">Name</label>
<input type="text" class="form-control" id="inputName">
</div>
<div class="form-group">
<label for="inputComment">Comments</label>
<textarea class="form-control" id="inputComment" rows="4"></textarea>
</div>
</form>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
<button type="button" class="btn btn-primary">Send</button>
</div>
</div>
</div>
</div>
</body>
</html>The jQuery code in the above example simply finds the <input> element and set focus on it when modal is visible to the user using the modal's shown.bs.modal event.
