Javascript SyntaxError:意外标记<；（…）-dojo/ajax

我在我的项目中使用以下AJAX

    var _getWeatherInfo = function(ntown){
    //Debugging
    console.log("Before dojo.xhrget");
      //dojo ajax request used to call the PHP file and retrieve the towns data
      dojo.xhrGet({
          handleAs: "json",
          timeout: 5000,
          //php file URL (location)
          url: "PHP/weather.php?ntown=" + ntown,

          load: function(results) {
              //send the results to the function _refreshWeatherList
              _refreshWeatherList(results);               
        }

    });
    //Debugging
    console.log("After dojo.xhrget");
}

以检索城市/城镇的天气数据。然而，我已经有一段时间没有参与这个项目了，我很难理解为什么它不再有效（上次我运行这个项目时它还在有效）

在浏览器控制台中，我收到以下错误：

我使用以下方法包括dojo：

<script src="//ajax.googleapis.com/ajax/libs/dojo/1.10.4/dojo/dojo.js"></script>

xhr响应：

我的问题无效/已折旧的mysql。我用MYSQLi重写了我的MYSQL，一切都安排妥当了。

我在从一个服务返回JSON时遇到了这个问题，我以前在该服务中var_转储了一些东西。不明飞行物。希望它能帮助一些人，因为我浪费了10分钟来找出原因。

xhr请求是否收到响应？你能把它寄出去吗？我想知道你的服务器是否返回了格式错误的json。听起来服务器响应的是XML而不是JSONSorry，因为回复太晚了。我做了一些进一步的工作，在xhr响应中发现了一些有用的信息（感谢Russell的建议！）。更新：从xhr响应中，我的SQL连接/语句显然有一些错误。现在都修好了。谢谢你的帮助。
