MOSS 2007 Web部件中的Ajax

Question

I am creating a web part in MOSS 2007 that contains an autocompleteextender.

I have ajax-enabled my site by adding all the configs in web.config (Example here)

My web service:

    [System.Web.Script.Services.ScriptService]
    public class AutoComplete : System.Web.Services.WebService
    {
        [System.Web.Services.WebMethod]
        [System.Web.Script.Services.ScriptMethod]
        public string[] GetCompletionList(string prefixText, int count)
        {
                    List<string> results = new List<string>();
                    results.Add("Here");
                    results.Add("Here");
                    results.Add("Here");
                    results.Add("Here");
                    results.Add("Here");
                    results.Add("Here");
                    results.Add("Here");
                    return results.ToArray();
         }
   }

I am able to hit the web service from web browser. However, the autocompleteextender does not call my web service.

My web service url: http://[myserver]/AutoComplete.asmx (I used this for the ServicePath of the extender). My web part page: http://[myserver]/Pages/mypage.aspx

I also tried to add a calendarextender onto the page and the calendar renders underneath the textbox and shows as inline html. Weird.

Any thought would be helpful.

Thanks

From you web service url it looks like you've put the web service into the root folder of your site. This will not work as this folder is handled by the SharePoint VirtualPathProvider which will look up files in the content database.

You should put your web service into a subdirectory or either 12Hive\ISAPI or 12Hive\LAYOUTS and then call it through the corresponding

http://[myserver]/_vti_bin/[Folder]/AutoComplete.asmx 

or

http://[myserver]/_layouts/[Folder]/AutoComplete.asmx
