popuppanel中的Pagemethods不会在IE9中第二次加载

标签: c# javascript internet-explorer-9 modalpopupextender pagemethods

我有一个主页面,其中有一些 pagemethod 被调用来执行某些活动。在此主页中使用 popuppanel (popuppanel内容页面也有页面方法)来显示一些细节。如果多次执行相同的操作(即多次打开弹出式面板),则除了IE9 之外的所有其他浏览器 正常(即使在IE8中也能正常工作)。但是,第一次时间执行 成功。正在使用的代码如下所示。

Scriptmanager如下:

<ajaxToolkit:ToolkitScriptManager runat="server" ID="TSCM1" EnablePageMethods="true" />

主页中的脚本:

function Clkd(){
     var ppnl=document.getElementById("if1");
     ppnl.src="Test1.aspx";
     $find('<%= MPE.ClientID %>').show();
}

function Clkd2(){
     var ppnl=document.getElementById("if1");
     ppnl.src="";
     $find('<%= MPE.ClientID %>').hide();
}

$(document).ready(function(){
     PageMethods.mainPageMethod("MainTest",cbackfn);
});

function cbackfn(str){
     alert(str);
}

页面方法:

 [System.Web.Services.WebMethod(EnableSession = true)]
        public static string mainPageMethod(String mainStr)
        {
            return mainStr + " Ok";
        }

Test1.aspx页面详情(这是弹出式面板中加载的页面):

以下脚本代码:

$(document).ready(function(){
     PageMethods.Testpm("Test",fnd);
});

function fnd(str){
     alert(str);
}

页面方法:

 [System.Web.Services.WebMethod(EnableSession = true)]
        public static string Testpm(String alrt)
        {
            return "Ok";
        }

如果第二次执行相同的操作(仅在IE9中)

,则抛出以下错误
SCRIPT5007: Unable to set value of the property '_UpdateProgress': object is null or undefined 
ScriptResource.axd?........

SCRIPT5007: Unable to get value of the property 'WebServiceProxy': object is null or undefined 
Test1.aspx, line 66 character 1

SCRIPT5007: Unable to get value of the property 'DomElement': object is null or undefined 
ScriptResource.axd?......, line 2 character 18851

SCRIPT5007: Unable to get value of the property 'add_init': object is null or undefined 
Test1.aspx, line 97 character 122

SCRIPT438: Object doesn't support property or method 'Testpm' 
Test1.aspx, line 11 character 4
  

重要提示:如果主页没有任何pagemethods,那么它的工作正常。   请帮我解决这个问题..

您应该添加相关的HTML,这可能有助于其他人帮助您。

我使用了你的代码并添加了丢失的代码,当我用它时,它在包括IE9在内的所有浏览器中都运行良好。

请在下面找到代码:

主页面(Default.aspx):

<head runat="server">
    <title></title>
    <script src="Scripts/jquery-1.9.1.js" type="text/javascript"></script>
    <script type="text/javascript">
        function Clkd() {
            var ppnl = document.getElementById("if1");
            ppnl.src = "test.aspx";
            $find('<%= MPE.ClientID %>').show();
        }

        function Clkd2() {
            var ppnl = document.getElementById("if1");
            ppnl.src = "";
            $find('<%= MPE.ClientID %>').hide();
        }
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <cc1:ToolkitScriptManager runat="server" ID="scriptmanager1">
    </cc1:ToolkitScriptManager>
    <asp:Panel ID="pnl1" runat="server">
        <iframe id="if1"></iframe>
        <asp:Button ID="btnHidePopup" runat="server" Text="Hide" />
    </asp:Panel>
    <asp:Button ID="btnShowPopup" runat="server" Text="Show" OnClientClick="Clkd();" />
    <cc1:ModalPopupExtender ID="MPE" runat="server" TargetControlID="btnShowPopup" PopupControlID="pnl1"
        DropShadow="true" OkControlID="btnHidePopup" OnOkScript="Clkd2()" CancelControlID="btnHidePopup">
    </cc1:ModalPopupExtender>
    </form>
</body>

<强> Test.aspx文件:

<head runat="server">
    <title></title>
    <script src="Scripts/jquery-1.9.1.js" type="text/javascript"></script>
    <script type="text/javascript">
        $(document).ready(function () {
            PageMethods.Testpm("Test", fnd);
        });
        function fnd(str) {
            alert(str);
        }
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
     <cc1:ToolkitScriptManager runat="server" ID="scriptmanageriframe" EnablePageMethods="true">
    </cc1:ToolkitScriptManager>
    Hello World this is game.
    </div>
    </form>
</body>

Test.aspx.ce(Webmethod):

 [System.Web.Services.WebMethod(EnableSession = true)]
        public static string Testpm(String alrt)
        {

            return "Ok";
        }

我希望它有所帮助!

你可以试试不同的popUp

例如:

  1. asp:ModalPopupExtender也可在ajaxtoolkit
  2. 中找到
  3. jquery对话框弹出窗口。

答案 2 :(得分:1)

我希望你在j#和jquery代码中使用相同的web方法,使用jquery对话框弹出而不是ajaxpopup面板。

答案 3 :(得分:1)

在MPE上使用ClientIdMode =“Static”并直接在$ find()中使用MPE ID。

ASPX代码:

<asp:ModalPopupExtender ID="modalpopup" ClientIDMode="Static" runat="server" CancelControlID="btnCancel"
OkControlID="btnOkay" TargetControlID="Button1" PopupControlID="Panel1" 
        Drag="true" >
</asp:ModalPopupExtender>

Javscript代码:

$find('modalpopup').show(); // to show popup
$find('modalpopup').hide(); // to hide popup

IE9在页面方法(主页,popuppanelpage)中都有页面方法时遇到页面方法问题。

您可以在webservice(.asmx)文件中使用pagemethods

我尝试如下:

<强> defaultpage.aspx

<head id="Head1" runat="server">
    <title>Untitled Page</title>
    <script language="javascript" type="text/javascript" src="http://code.jquery.com/jquery-1.8.3.min.js"></script>
    <script type="text/javascript">

      function fnd123(str){
          alert(str);
    }

     function objFailed1(data) {
     fnd123(data);
      }
     function objGot1(data) {

                        fnd123(data.d);

             }
    function Clkd(){
    var ppnl=document.getElementById("if1");
    $.ajax({
             url: "Testser.asmx/GetData",
             contentType: "application/json; charset=utf-8",
             dataType: "json",
             data:'{"FileName":"Data from default page"}',
             type: 'POST',
             success:objGot1,
             error: objFailed1
         });
    ppnl.src="Test1.aspx";
     $find('MPE').show();
    }


     function Clkd2(){
    var ppnl=document.getElementById("if1");
     ppnl.src="";
     $find('MPE').hide();
     //PageMethods.clearPageData("/Test1.aspx",fnd1);
    }
