Pagemethods in asp.net

问题:

My Pagemethod implementation is not working in Chrome browser. I have ASP.NET 3.5 web application developed in VS 2008.

The code below not working in chrome or Safari:

function FetchDataOnTabChange(ucName)
{ 
    PageMethods.FetchData(ucName, OnSuccessFetchDataOnTabChange, OnErrorFetchDataOnTabChange);
}

function OnErrorFetchDataOnTabChange(error)
{   
   //Do something
}

function OnSuccessFetchDataOnTabChange(result)
{
   //Do something  
}

Sorry for the late response, but if any one stumbles on this later, this should work in all browsers by following the steps below.

• The page method must have the System.Web.Services.WebMethod attribute. [WebMethod]
• The page method must be public. [WebMethod] public ...
• The page method must be static. [WebMethod] public static ...
• The page method must be defined on the page (either inline or in the code-behind). It cannot be defined in a control, master page, or base page.
• The ASP.NET AJAX Script Manager must have EnablePageMethods set to true.

This is from a working application

aspx page:

/* the script manager could also be in a master page with no issues */
<asp:ScriptManager ID="smMain" runat="server" EnablePageMethods="true" />
<script type="text/javascript">
    function GetDetails(Id) {
        PageMethods.GetDetails(doorId);
    }
</script>

code behind:

[System.Web.Services.WebMethod]
public static void GetDetails(string Id)
{

}

Good luck! :-)
