Question

我有ajax调用如下

$.ajax({
  type: "POST",
  url: "MainPortal/VirtualRoomService.asmx/SaveJunit",
  data: JSON.stringify({
    xjunit: junit,
    data: editor.getData().trim()
  }),
  contentType: "application/json; charset=utf-8",
  async: false,
  dataType: "json",
  success: function(result) {
    if (result.d.split('|')[0] != "-1") {
      $("#<%=lblMessage.ClientID%>").text("Junit saved successfully");
    } else {
      $("#<%=lblMessage.ClientID%>").text(result.d.split('|')[1]);
    }
  },
  error: function(result) {
    if (result.status == 200 && result.statusText == 'OK') {} else {
      alert("FAILED : " + result.status + ' ' + result.statusText);
    }
  }

});

以下是.asmx web服务

ajax调用总是返回200 OK，但从不调用该函数在客户端调试器（chrome）

中捕获的请求数据下方

 {"xjunit":"<?xml version=\"1.0\" encoding=\"utf-8\"?><junit><byline>Mohan</byline><id></id><capid>102</capid><status></status><slug> 17</slug><tags>tags</tags><publication>21</publication><type><id>17</id><name>Text</name></type><label>21</label><deck>deck1</deck><intro>intro</intro><info><infodate></infodate><infotime></infotime><infoloc>loc</infoloc><infotext>info</infotext></info><createdby>7</createdby></junit>","data":"<p>content</p>"}

更新

我已经改变了

error: function(result) {

到

error: function (jqXHR, textStatus, errorThrown) {

了解错误。 textStatus显示为parsererror，而errorThrown显示意外的输入结束

Answer 1

更改此行：

data: JSON.stringify({xjunit: junit, data: editor.getData().trim()}),

到：

data: {xjunit: junit, data: editor.getData().trim()},

Ajax调用返回200 OK但不调用web方法
