JQuery：调用Web服务

我正在开发SilverLight应用程序，其中在浏览器关闭事件中，我需要执行Web服务调用。我有一个接受一个参数的Web服务方法。当用户点击浏览器关闭事件时。我将会调用doRelease（）函数。 releaseuser方法需要一个参数usertoken。JQuery：调用Web服务

我在调用我的jQuery函数CallService（）时出错。

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"); 
    }

由于在你的例子中少于50行，你可以给我们所有的提示什么代码是在你的实际页面186行吗？ :) – 2010-08-25 11:11:22

它在进入函数CallService（）时发生。你可以说发送我的参数？这是对的吗？ – xscape 2010-08-25 11:25:55

这与Silverlight有什么关系？ – Pointy 2010-08-25 12:38:25

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); 

      } 
     } 
    }

这看起来有点奇怪： -

function doRelease() { 

    var usertoken = readCookie("usertoken"); 


    Temp("usertoken"); 
}

首先，我们假设readCookie是做正确的事？

其次应该是最后一行是： -

Temp(usertoken);

三，凡在这一切的 “Silverlight的” 角？

数据必须包装为一个对象。在CallService功能，更改：

data: varData,

到：

data: "{input:'" + varData + "'}",

“INPUT” 改变实际参数名称在Web服务方法。
