使用JQuery调用Asmx Web服务时出错 [英] Error calling asmx web service with JQuery

问题描述

我正在尝试使用JQuery调用asmx Web服务.我收到未定义的错误.

I a asmx webservice I am trying to call using JQuery. I am getting the error undefined .

function WebMethod(fn, paramArray, successFn, errorFn) {

    //----------------------------------------------------------------------+
    // Create list of parameters in the form:                               |
    // {'paramName1':'paramValue1','paramName2':'paramValue2'}              |
    //----------------------------------------------------------------------+
    var paramList = '';
    if (paramArray.length > 0) {
        for (var i = 0; i < paramArray.length; i += 2) {
            if (paramList.length > 0) paramList += ',';
            paramList += '"' + paramArray[i] + '":"' + paramArray[i + 1] + '"';
        }
    }
    paramList = '{' + paramList + '}';
//   url: 'http://service.4dpeeps.com/TSService/ImagesService.asmx' + '/' + fn,
    $.ajax({
        url: '../ImagesService.asmx' + '/' + fn,
        global: false,
        type: "POST",
        dataType: 'json',
        data: paramList ,
        contentType: 'application/json; charset=utf-8',
        success: successFn,
        error: errorFn
    });
    //----------------------------------------------------------------------+
    // Call the WEB method                                                  |
    //----------------------------------------------------------------------+
   // $.ajax({ data: paramList });
}

// xhrFields: {
//            withCredentials: true
//        },
//---------------------------------------------+
// jQuery AJAX Call Succeeded.                 |
//---------------------------------------------+
function AjaxSucceeded(result) {
    alert(result.d);
    var tableView = $find(RgImages).get_masterTableView();
    tableView.set_dataSource(result);
    tableView.dataBind();

}

//------------------------------------------------+
// jQuery AJAX Call FAILED.                       |
//------------------------------------------------+
function AjaxFailed(result) {



    DoSomething(result.d);
}


function DoSomething(msg) {
    // Do something with the response data here.
    //  Expect it to consistently have no .d.
    alert('SERVICE Failed : ' + msg);
}

这是我的网络服务.它从不进入Web服务，但是在javascript中失败

This is my webservice. It never makes it to the webservice but fails in the javascript

Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.ComponentModel
Imports TsBusiness.TsBusiness
Imports System.Web.Script.Services

Namespace TSWebServices
    ' To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
    ' <System.Web.Script.Services.ScriptService()> _

    <System.Web.Services.WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
    <System.Web.Script.Services.ScriptService()> _
    <ToolboxItem(False)> _
    Public Class ImagesService
        Inherits System.Web.Services.WebService

        Private mImageUpload As Images.Images
    
        <WebMethod(MessageName:="Images by Ids")> _
      <ScriptMethod(UseHttpGet:=True, ResponseFormat:=ResponseFormat.Json)> _
        Public Function GetImageURLs(ByVal id As Integer) As List(Of TsDbAccess.ts_ImagesResult)
            ' mImageUpload = New Images.Images
            Return mImageUpload.GetImages(id)
        End Function
    End Class
End Namespace
