Ajax responseText不起作用

在我的ajax中，当我运行ajax.respondText时，由于某种原因，我有一个名为ajax的var。

在php代码中，我要求它返回一个登录的用户名。好吧它是回显出用户的名字，但也回显了我的网站的标题在混合中，你可以看到这里 - 安德鲁在第一组代码的底部。这是唯一应该回应的不是前面的html。

什么可能导致我的标题被包含在我的响应中所以我确实更加深入并运行了一个console.log只是var ajax。这给了我这个

响应是我的标题。

我要问的是请查看下面的代码并试图帮助我理解为什么会这样。我很困惑，我已尽力解决它。

答案 0 :(得分：1)

这是来自php脚本顶部的以下两个中的任何一个：

include 'core/init.php'; include 'includes/overall/header.php';

因此，在ajax调用的时间内限制不需要的输出或文件包含。
