我有一张登记表，在那里我试图注册新成员。我试图在wordpress中传递图像上传的formdata和ajax操作。目前，我正在尝试在控制台中打印这些值。但是ajax函数根本没有被调用，因为操作不起作用。我该怎么做呢。请帮帮我。

HTML

<form id="landlordregform" method="post" action="" enctype="multipart/form-data" novalidate="novalidate">
   <div class="registrationformbox landloardregformbox">
      <div id="custommsg"></div>
      <table width="100%">

            <tr>
               <td><input type="text" name="username" placeholder="USERNAME*" id="username" class="valid" aria-invalid="false"></td>
               <td><input type="password" name="password" placeholder="PASSWORD*" id="password" class="valid validate-equalTo-blur" aria-invalid="false"></td>
