提交post jquery后无法重置表单

Question

我尝试使用post jquery插入表单数据，以便将数据成功处理到数据库中，但问题是如何在不重新加载表单的情况下重新恢复表单，因此在我更改后隐藏不再出现选项$(".access")？

<button type="button" id="add-user" class="btn btn-success"><i class="fa fa-plus"></i> Add user</button>
</br>
<div class="row">
    <div class="from-user" style="display: none">
    <form id="form-add" class="form-horizontal">        
    <div class="form-group">
        <div class="col-md-6">
            <div class="nama">
              <label for="nama">Name * :</label>
              <input type="text" name="name" id="name" class="form-control" type="text"  required />
              <div class="help-block with-errors"></div>
            </div>
        </div>
    </div>
    <div class="form-group">
        <div class="col-md-6">
            <div class="nama">
              <label for="nama">Address * :</label>
              <input type="text" name="address" id="address" class="form-control" type="text" required />
              <div class="help-block with-errors"></div>
            </div>
        </div>
    </div>  

    <div class="form-group">
