Javascript jquery - 未捕获的类型错误 : Illegal invocation

Question

我试图通过发布一些 xml 来登录来测试登录 Web 服务，但它再次出现此错误:

未捕获的类型错误:非法调用

这是代码:

$(document).ready(function() {
  var data = $.parseXML("<authenticationDetail><userName>username</userName><password>passw</password></authenticationDetail>");
  var url = "http://127.0.0.1:8000/thelogin.ws";
   $.ajax({ 
        data: data,
        type: "POST", 
        contentType: "application/xml", 
        url: url,
        dataType: "xml",
        success: function(xml) { // callback called when data is received 
              alert("success to post");
        },
        error: function() { // callback called when error
              alert("fail to post");
        }
  });
});

我该如何解决这个问题？

Answer 1

尝试改变:

var data = $.parseXML("<authenticationDetail><userName>username</userName><password>passw</password></authenticationDetail>");

致:

var data = "<authenticationDetail><userName>username</userName><password>passw</password></authenticationDetail>";

您发送的是 XML，而不是已解析的 XML。
