javascript - Form not submitting when clicking submit button -

i added javascript validation form on website. site connects db fine, when click on submit button, no action taken.

this form located in footer of page:

<div id="add_restaurant" class="full-shadow">     <h4>add restaurant</h4>      <form name="submitform" action="<?php echo $pagename ?>" method="post">          <ul class="radio_list" id="category">             <li>category:</li>             <li><label class="radiobtn"><input name="category" type="radio" value="healthy" id="is_healthy" checked="checked"/>healthy</label></li>             <li><label class="radiobtn"><input name="category" type="radio" value="unhealthy" id="is_unhealthy"/>unhealthy</label></li>         </ul>         <br />         <label>name:</label>&nbsp;<input name="rest_name" id="rest_name" type="text" autocomplete="off"/>         <input id="submit" type="submit" name="submit" value="submit">     </form>      <p id="add_thanks"></p> </div> 

i imagine problem simple i'm over-looking. can help?

edit: i've found issue here in js validation:

$('#submit').off('click').on('click', function(){     if($('#rest_name').val() === ""){         $('#add_thanks').html("please type in restaurant name.");     }     return false; }); 

if disable code, form works. causing problem in javascript code?

you not printing $pagename:

<form name="submitform" action="<?php echo $pagename ?>" method="post">
