JS，Jquery 调用 C#WebService

1，需要在服务下面把代码的注释去掉

　　// 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消对下行的注释。
　　//[System.Web.Script.Services.ScriptService]

2,JS 调用方法如下

var request = '<?xml version="1.0" encoding="utf-8"?>';request += '<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">'request += '<soap12:Body>'request += '<UpdateFacultativere xmlns="http://tempuri.org/">'request += '   <facNum>12313</facNum>'request += '  <facVerstion>2</facVerstion>'request += '   <date>string</date>'request += ' <description>string</description>'request += ' </UpdateFacultativere>'request += '</soap12:Body>'request += '</soap12:Envelope>'var req = new XMLHttpRequest();req.open("POST", 'http://localhost:34869/CRMService.asmx', true)// Responses will return XML. It isn't possible to return JSON.//req.setRequestHeader("Accept", "application/xml, text/xml, */*");req.setRequestHeader("Content-Type", "application/soap+xml; charset=utf-8");req.setRequestHeader("Content-Length:", request.length);req.setRequestHeader("SOAPAction", "http://tempuri.org/UpdateFacultativere");req.onreadystatechange = function () { DoR(req, successCallback, errorCallback); };req.send(request);

　　

3，Jquery调用方法如下

            $.ajax({url: 'http://localhost:34869/CRMService.asmx/UpdateFacultativere',data: {facNum :'02020',facVerstion:10, date:'10292', description:'2222'},dataType: "xml",type: "POST",success: function (xml) {debuggeralert(xml);},error: function (xml, status) { debugger}});
