jquery ajax form submit

Question

Is this code correct? I\'m trying to submit it and also I would like on submit if text area would be empty again.

Answer 1

​$(function(){
    $("form#submit").submit(function(e){
        e.preventDefault();
        var fid = $(".messag").attr("id");
        var val = $("#mess_ar").val();
        $.ajax({
            type: "POST",
            url: "send_message.php",
            data: "fid="+ fid +"&val="+ val,
            success: function(){
                $("#mess_ar").val("");
            }
        });
    });
});​

Use

$("#submit").on('submit', function(e){...});

instead of

$("#submit").submit(function(e){...});

if you are using latest version of jquery.
