Question

我想附加表格，但问题是它没有在表格中添加任何内容

<%@page import="database.FoodServiceDAO"%>
<%@page import="beans.categoryBean"%>
<%@page import="java.util.ArrayList"%>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
 pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"   "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<body>
<table id="table_design">
<tr id="categorys">
</tr>
</table>

<script type="text/javascript" src="javascript/jquery.js"></script>
<script type="text/javascript" src="javascript/ajax.js"></script>
</body>
</html>

现在我只想附加一个表ajax的代码，如下所示，问题是没有填充任何内容

$(function () {

var $categorys = $('#categorys');
$.ajax({ 
    type: 'GET' ,
    url: '/controller?action=category' ,
    success: function(categorys){
        $.each(categorys, function(i, categorys){

            $categorys.append("<td><h1>Heelo</h1></td>") ;

        });

    }

    });
 });

Ajax填充表
