html - How to submit a form that is loaded using jquery -

i have file contain html form php , loaded file using jquery , when try submit form ,the form doesn't submit , , refresh page file contain form loaded disappear. files:

$(document).ready(function() {  $('#admin_profile').click(function () {         $('#main').load('profile_admin.php', null, function () {              $('#addtot').click(function () {                 $('#cont').load('add.php');             })      }); }); }) 

my form exist in add.php it's simple form

 <form method="post" >       <td><input name="title" type="text"></td>       <td><textarea name="cont"></textarea></td>       <input type="submit" name="sendmsg" value="send msg"> </form> 

and php exist in same file , mean form , php code

if(isset($_post['sendmsg'])){             $title=mysqli_real_escape_string($connect,$_post['title']);             $cont=mysqli_real_escape_string($connect,$_post['cont']);             if(empty($title) || empty($cont)) {                 echo "some fields empty";             }             else {                 $qr8=$connect -> query("insert msg(title,cont) values ('$title','$cont')") or die($connect->error);                 if($qr8) {                     echo "success";                 }             }         } 

what want when click on submit button want form submit , message success or fields empty show on same div file loaded,

i guess php showed in add.php. need change form to:

<form method="post" action="add.php">     ... </form> 

if form doesn't have action attribute, uses url of current document. when form loaded javascript, that's document did loading, not pulled from.
