Use the same script for multiple forms

How do I use only one script for multiple forms?

  <script>
    $(document).ready(function() {
        $("#formPost").submit(function() {
            var dados = $(this).serialize();

            $.ajax({
                type: 'POST',
                url: 'https://jsonplaceholder.typicode.com/posts',
                data: dados,
                success: function(data) {

                }
            });
            return false;
        });
    });
</script>

<form action="" method="POST" id="formPost">
    <input type="text" name="title" />
    <input type="text" name="body" />
    <input type="submit" value="Enviar" />
</form>

Thank you in advance!
