我使用jQuery的數據表,並得到這樣的警告消息:DataTables警告:table = userTable - 無效的JSON響應?
數據表警告:表=用戶表 - 無效JSON響應
一個servlet取從MySQL用戶,我想在jQuery的數據表顯示,但Ajax無法解析JSON或者JSON在servlet中生成錯誤?
的Servlet:
List<UserDTO> users = this.service.getAllUser();
Gson gson = new Gson();
request.setAttribute("users", gson.toJson(users));
request.getRequestDispatcher("listAllUser.jsp").forward(request, response);
JSP:
<%@ 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">

$(document).ready(function() {
$('#userTable').dataTable({
"processing" : true,
"serverSide" : true,
"ajax" : {
"url" : "ListAllUserServlet",

});
});
</script>
</head>
<body>
<table id="userTable" class="display">
<thead>
<tr>
<th colspan="10" id="userList">Users</th>

<tr>
<th>User id</th>

<tfoot>

JSON由servlet的產生:
[
{
"id": 1,
"userName": "userName1",
"firstName": "firstName1",
"lastName": "lastName1",
"email": "[email protected]",
"phone": "36202080085",
"location": "location1",
"password": "password1",
"gender": "m",
"birthday": "1-02-2015"
}
]
刪除 「服務器端」 的:真正爲我工作! –
