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) {
                    debugger
                    alert(xml);
                },
                error: function (xml, status) { 
                    debugger
                }
            }
            );
