JQuery.ajax将无法识别来自JSP的JSON响应

Question

我正在尝试使用JSP、Jquery和AJAX编写一个简单的应用程序，以便在页面上获取和显示数据。

下面是我的ajax函数：

    $.ajax({
                type:"POST",
                url:"interface_load_status_page.jsp",
                data:dataString,
                dataType:"json",
                success: function(data, textStatus, jqXHR){
                    $("#response").html("");
                    $("#response").append(data);
                },
            });

只要dataType设置为"text“，ajax调用就可以正常工作。不幸的是，当它被设置为json时，我需要它工作。下面是ajax函数调用的JSP的代码

<%
        response.setContentType("application/json");
        response.setCharacterEncoding("UTF-8");

            String date = request.getParameter("date");
            System.out.println("Date: "+date);  
        if (date != null) {
                DBAccess acc = new DBAccess();
                ArrayList<InterfaceLoadStatus> loadStatus = acc
                        .loadStatusQuery(date);
                //System.out.println(loadStatus);
                out.println(Utils.getJSONLoadStatus(loadStatus));
            }
        %>

JSP所做的是将查询结果转换为JSON格式，如下所示：

{"success":true,"interfaceloadstatus":[{"bType":"COC","start":"2013-04-22 03:30:10.0","end":"2013-04-22 04:35:38.0","exe":"01:05:28","handOff":"Y"},{"bType":"DST","start":"2013-04-22 00:10:09.0","end":"2013-04-22 00:23:17.0","exe":"00:13:08","handOff":"Y"},{"bType":"HTL","start":"2013-04-22 00:10:10.0","end":"2013-04-22 01:17:14.0","exe":"01:07:04","handOff":"Y"},{"bType":"RC","start":"2013-04-22 00:10:11.0","end":"2013-04-22 00:45:17.0","exe":"00:35:06","handOff":"Y"},{"bType":"AIR","start":"2013-04-22 03:00:16.0","end":"2013-04-22 04:03:58.0","exe":"01:04:42","handOff":"Y"},{"bType":"VP","start":"2013-04-22 03:00:16.0","end":"2013-04-22 04:03:58.0","exe":"01:04:42","handOff":"Y"},{"bType":"AIR-IAR","start":"2013-04-22 09:45:06.0","end":"2013-04-22 10:24:51.0","exe":"00:40:45","handOff":"Y"}]}

好了，现在JSON输出是固定的，但是JQuery ajax函数仍然不能识别它

Answer 1

根据www.jsonlint.com的说法，每一行都是有效的JSON。另一方面，并不是整个输出都是有效的json，所以如果不是逐行输入，这可能是原因所在。

Answer 2

我知道这个问题很老了，你可能早就忘记了它，但我刚刚遇到了同样的问题，所以我想我应该分享我所做的，以防其他人正在寻找解决方案。

如下所示：

JSP

<%@ page contentType="text" %>

*JSON here*

JS

var jsonData = JSON.parse(data);
