Trying to clear fields in html javascript

Question

I am trying to make a button that cleans specific fields of my page. This is what I have, but it does not work. Not sure what else to do. Some folks tried to help me on the commends of another topic but since I could not make it work I opened this new question.

Thanks

Answer 1

You're calling $('.clear') before the elements exist.

Therefore, you're adding the event handler to an empty set.

You need to run your <script> block after the elements.

Answer 2

Maybe you can try, instead of:

<script>

    $('.clear').on('click', function () {
        $('#inputFirstName').val('');
        $('#inputLastName').val('');
        $('#inputEmail').val('');
    });

</script>

Instead have:

<script>
    $(document).ready(function () {
        $('.clear').on('click', function () {
            $('#inputFirstName').val('');
            $('#inputLastName').val('');
            $('#inputEmail').val('');
        });
    });
</script>
