    JavaScript Functions That Call WebService Methods Are Not Working

    in JavaScript

    Posted

    Hello,
    very simple code block is below. Javascript functions that call web service methods are working when I called them between form tags. But they are not working at the beginning of the page.
    I specified lines that are not working below.
    Please help.
    <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %>
    <!DOCTYPE html>
    <head runat="server">
    <title></title>
    <script type="text/javascript">
    function GetMyName() {
    WebService1.GetName(onNameSuccess, onNameFailure);
    }
    function onNameSuccess(result) {
    return result;
    }
    function onNameFailure(result) {
    alert("There is an error");
    }
    function GetMySurname() {
    WebService1.GetSurname(onSurnameSuccess, onSurnameFailure);
    }
    function onSurnameSuccess(result) {
    return result;
    }
    function onSurnameFailure(result) {
    alert("There is an error");
    }
    //JAVASCRIPT FUNCTIONS ARE NOT WORKING HERE
    //THESE TWO LINES ARE NOT WORKING
    var name = GetMyName();
    var surname = GetMySurname();
    </script>
    </head>
    <body>
    <form id="form1" runat="server">
    <asp:ScriptManager ID="ScriptManager1" runat="server">
    <Services>
    <asp:ServiceReference Path="WebService1.asmx" />
    </Services>
    </asp:ScriptManager>
    //JAVASCRIPT FUNCTIONS ARE WORKING HERE
    </form>
    </body>
    </html>
