【问题描述】：
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");
}
为了检索城市/城镇的天气数据。但是，自从我从事这个项目以来已经有一段时间了，我无法理解为什么它不再起作用（我上次运行这个项目时它还在起作用）。
在浏览器控制台中我收到以下错误：

我包括道场使用：

【问题讨论】：
-
xhr 请求是否收到响应？你能贴出来吗？我想知道您的服务器是否返回格式错误的 json。
-
听起来服务器响应的是 XML 而不是 JSON
-
抱歉回复晚了。我做了一些进一步的工作，并在 xhr 回复中找到了一些有用的信息（感谢 Russell 的建议！）。
-
更新：从 xhr 响应来看，我的 SQL 连接/语句显然有一些错误。现在都修好了。感谢您的帮助。
