我正在开发一个 SilverLight 应用程序,其中在浏览器关闭事件中,我需要进行 Web 服务调用。我有一种接受一个参数的网络服务方法。当用户点击浏览器关闭事件时。我将调用 doRelease() 函数。 releaseuser方法需要一个参数usertoken。

当我调用 jQuery 函数 CallService() 时出现错误。

Line: 186 Error: Object expected

 var varType;
var varUrl;
var varData;
var varContentType;
var varDataType;
var varProcessData;
//Generic function to call AXMX/WCF Service
function CallService() {
$.ajax({
type: varType, //GET or POST or PUT or DELETE verb
url: varUrl, // Location of the service
data: varData, //Data sent to server
contentType: varContentType, // content type sent to server
dataType: varDataType, //Expected data format from server
processdata: varProcessData, //True or False
success: function (msg) {//On Successfull service call
alert("success");
ServiceSucceeded(msg);
},
error: ServiceFailed// When Service call fails
});
}

function Temp(usertoken) {
varType = "POST";
varUrl = "http://localhost/TempWS/MachineHistoryWS.asmx?op=ReleaseUser";
varData = usertoken;
varContentType = "application/json; charset=utf-8";
varDataType = "json";
varProcessData = true;

alert("call service");

CallService();

}
function ServiceSucceeded(result) {//When service call is sucessful

alert("success");

varType = null; varUrl = null; varData = null; varContentType = null; varDataType = null; varProcessData = null;
}
function ServiceFailed(result) {
alert('Service call failed: ' + result.status + '' + result.statusText);
varType = null; varUrl = null; varData = null; varContentType = null; varDataType = null; varProcessData = null;
}



function doRelease() {

var usertoken = readCookie("usertoken");


Temp("usertoken");
}

最佳答案

我解决了我的问题,但没有使用jquery。这是我的解决方案。

function sendDataAsXML_SOAP() {
var req_params = "", url = "", number = 0, type = "";
/* Configure Parameters */
url = "http://localhost/TempWS/MachineHistoryWS.asmx";
user = "129272802615082804";

req_params = "<?xml version=\"1.0\" encoding=\"utf-8\"?><soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">";
req_params = req_params + "<soap:Body><ReleaseUser>";
req_params = req_params + "<credentials>" + user + "</credentials></ReleaseUser></soap:Body></soap:Envelope>";
alert(req_params);
/* Send XML/SOAP Request To Web Service Using Browser's Javascript DOM */
try {
ajax_request = new XMLHttpRequest();
}
catch (trymicrosoft) {
try {
ajax_request = new ActiveXObject("Msxml2.XMLHTTP");
}
catch (othermicrosoft) {
try {
ajax_request = new ActiveXObject("Microsoft.XMLHTTP");
}
catch (failed) {
ajax_request = false;
}
}
}
ajax_request.open("POST", url, true);
ajax_request.setRequestHeader("Content-Type", "text/xml;charset=utf-8");
ajax_request.onreadystatechange = receiveXML_SOAPData;
ajax_request.send(req_params);
}

function receiveXML_SOAPData() {
if (ajax_request.readyState == 4) {
if (ajax_request.status == 200) {
alert(ajax_request.responseText);

}
}
}
