Jquery Ajax方法调用错误

本文介绍了Jquery Ajax方法调用错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

这是我的Jquery方法

var domain = $（domainId）.parent（）。find（input [name $ = whoisdomain]）VAL（）; var params ={domainname：'+ domain +'}; $ .ajax（{类型：'POST'， url：'.. / SearchResult.aspx / GetResult'， contentType：'application / json ; charset = utf-8'， data：params， dataType：'json'， processData：true，成功：AjaxSucceeded，错误：AjaxFailed }）; 服务器端WebMethod Is： [WebMethod] [ScriptMethod（ResponseFormat = ResponseFormat.Json）] public静态列表< 字符串 > GetResult （字符串域名） { //代码在这里}

错误是： {消息：无效的Web服务调用，缺少参数值：\ u0027domainname \ u0027。，StackTrace：at System.Web.Script.Services System.Web上的System.Web.Script.Services.WebServiceMethodData.CallMethodFromRawParams（Object target，IDictionary`2 parameters）\\\\ n中的.WebServiceMethodData.CallMethod（Object target，IDictionary`2参数）\\\\ n .Script.Services.RestHandler.InvokeMethod（HttpContext context，WebServiceMethodData methodData，IDictionary`2 rawPa rams）\\\ at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall（HttpContext context，WebServiceMethodData methodData），ExceptionType：System.InvalidOperationException} Plz告诉我错误在哪里..这个代码在除了Internet Explorer之外的所有浏览器中都能正常工作10

解决方案

（domainId）.parent（）。find（input [name

= whoisdomain] ）.VAL（）; var params ={domainname：'+ domain +'};

.ajax（{ type：'POST'， url：'../SearchResult.aspx/GetResult'， contentType：'application / json; charset = utf-8'， data：params， dataType：'json'， processData：true，成功：AjaxSucceeded，错误：AjaxFailed }）; 服务器端WebMethod Is： [WebMethod] [ScriptMethod（ResponseFormat = ResponseFormat.Json）] public静态列表< 字符串 > GetResult （字符串域名） { //代码在这里}

This is my Jquery Method

var domain = $(domainId).parent().find("input[name$=whoisdomain]").val(); var params = "{domainname:'" + domain + "'}"; $.ajax({ type: 'POST', url: '../SearchResult.aspx/GetResult', contentType: 'application/json; charset=utf-8', data: params, dataType: 'json', processData:true, success: AjaxSucceeded, error: AjaxFailed }); Server side WebMethod Is: [WebMethod] [ScriptMethod(ResponseFormat = ResponseFormat.Json)] public static List<string> GetResult(string domainname) { //code is here }

ERROR IS: {"Message":"Invalid web service call, missing value for parameter: \u0027domainname\u0027.","StackTrace":" at System.Web.Script.Services.WebServiceMethodData.CallMethod(Object target, IDictionary`2 parameters)\r\n at System.Web.Script.Services.WebServiceMethodData.CallMethodFromRawParams(Object target, IDictionary`2 parameters)\r\n at System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams)\r\n at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"} Plz tell me where is the error..this code work fine in all browers except Internet Explorer 10

解决方案

(domainId).parent().find("input[name

=whoisdomain]").val(); var params = "{domainname:'" + domain + "'}";

.ajax({ type: 'POST', url: '../SearchResult.aspx/GetResult', contentType: 'application/json; charset=utf-8', data: params, dataType: 'json', processData:true, success: AjaxSucceeded, error: AjaxFailed }); Server side WebMethod Is: [WebMethod] [ScriptMethod(ResponseFormat = ResponseFormat.Json)] public static List<string> GetResult(string domainname) { //code is here }
