Javascript 错误：XMLHTTPRequest失败。。。为什么？

我的网站上有两张表格。它们都有电子邮件地址，代码都是一样的。第一个表单工作正常，但第二个表单出现XMLHTTPRequest失败错误。为什么会这样

以下是错误：

Could not accept email address: XMLHttpRequest failed: {"statusText":"","status":0,"response":"","responseType":"","responseXML":null,"responseText":"","upload":{"ontimeout":null,"onprogress":null,"onloadstart":null,"onloadend":null,"onload":null,"onerror":null,"onabort":null},"withCredentials":false,"readyState":4,"timeout":0,"ontimeout":null,"onprogress":null,"onloadstart":null,"onloadend":null,"onload":null,"onerror":null,"onabort":null}

代码如下：

你能在这里显示表格吗？确切的错误是什么？记录的错误是什么。消息说用error和htmlh更新了你是否尝试用id或name来引用输入，而不是class@hex494D49是的，我还是会犯同样的错误
