ReferenceError: userInfo is not defined是一个JavaScript错误。它表示在当前的代码环境中,没有定义名为userInfo的变量或对象。这个错误可能发生在你试图访问或使用一个不存在的变量或对象时。要解决这个错误,你需要确保在使用userInfo之前先定义它。你可以通过声明和初始化一个名为userInfo的变量来定义它。例如,你可以使用以下代码来定义userInfo:
var userInfo;
然后,你可以在之后的代码中使用userInfo。但是请注意,具体的解决方法可能因你的代码环境而异。你可能需要检查你的代码,了解userInfo应该在哪里定义,并确保它在使用之前已经定义好了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
