How do I clear clear a div when modal closes using Twitter boostrap?
===

Say I submit the form, it either gives me an error or a success message. I close the modal and if I click to open it again, the message is still there. How do I clear it?

    $("#JqAjaxForm").submit(function(e){                
            e.preventDefault();
                
            dataString = $("#JqAjaxForm").serialize();

            $.ajax({
                type: "POST",
                url: "update.php",
                data: dataString,
                dataType: "json",
                success: function(data) {
                //clearForm("#JqAjaxForm");
                        
                    if(data.email_check == "invalid"){ 
                        $("#message_ajax").html("<p class='alert alert-error'>Sorry " + data.name + ", " + data.email + " is NOT a valid e-mail address. Try again.</p>");
                    } else {                        
                        $("#message_ajax").html("<p class='alert alert-success'>" + data.newpasswd + " is a valid e-mail address. Thank you, " + data.name + ".</p>"); 
                    }     
                }                
            });                 
    });

And I call the modal via 

    <a data-toggle="modal" href="#chg_settings">Settings</a>

Here's the message div

    <div id="message_ajax"></div>
