将 UpdatePanel 添加到页面后不再调用 PageMethod

我在 asp.net 2.0 上使用 asp.net ajax 1.0 版。（我还无法升级到 3.5）

我有一个可以由 Javascript 调用的 PageMethod。在我将 UpdatePanel 添加到页面的其他部分之前，这一切都非常有效。现在，当我在打开调试的情况下运行页面时，页面方法中的断点永远不会被调用。当我在 firebug 中查看调用 PageMethod 的 post 时返回的内容时，我注意到返回了整个 aspx 页面，而不仅仅是调用值。我做了什么？

以下是对 PageMethod 的 Javascript 调用：

function EndRequestHandler(sender, args) {
    $('#selectedCHK').change(
        function() {
            var chkedInput = $('#selectedCHK');
            var networkRead = chkedInput[0].checked;
            PageMethods.ChangeSelectedNetworkReadFlag(routeNum, 
                                                      networkRead, 
                                                      function(msg) { alert(msg);  });
        }
    );
}
$(document).ready(function() {
    Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
}

在每个请求结束时调用 EndRequestHandler 函数的要点是，id 为“#selectedCHK”的项目位于更新面板内，并且每次 UpdatePanel 时都需要设置该事件被刷新了。

I am using asp.net ajax version 1.0 on asp.net 2.0. (I cannot yet upgrade to 3.5)

I had a PageMethod that would get called by Javascript. This worked perfectly until I added an UpdatePanel to another part of the page. Now when I run the page with debug turned on The breakpoint in the pagemethod never gets called. when I look in firebug at what gets returned when the post to the PageMethod is called, I notice that the entire aspx page is returned instead of just the calls value. What have I done?

Here is the Javascript call to the PageMethod:

function EndRequestHandler(sender, args) {
    $('#selectedCHK').change(
        function() {
            var chkedInput = $('#selectedCHK');
            var networkRead = chkedInput[0].checked;
            PageMethods.ChangeSelectedNetworkReadFlag(routeNum, 
                                                      networkRead, 
                                                      function(msg) { alert(msg);  });
        }
    );
}
$(document).ready(function() {
    Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
}

The point of having the EndRequestHandler function called at the end of each request is that the item with the id '#selectedCHK' is inside the update panel and the event needs to get set every time the UpdatePanel is refreshed.

尝试在更新面板上将更新模式设置为有条件。听起来更新面板正在劫持您的事件。

<asp:UpdatePanel ID="upMyPanel" UpdateMode="Conditional" runat="server">

Try setting the updatemode to conditional on your update panel. Sounds like the update panel is hijacking your events.

<asp:UpdatePanel ID="upMyPanel" UpdateMode="Conditional" runat="server">

我发现这是一个配置问题。具体来说，我需要添加：

<httpModules>
    <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
</httpModules>

在内部分。

我认为我已经正确配置了该站点，但我决定查看文档< /a> 一步一步。

I figured this out and it was a configuration problem. Specifically I needed to add:

<httpModules>
    <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
</httpModules>

inside the <system.web> section.

I thought that I had configured the site properly but I decided to go through the documentation step by step.
