JQuery ajax调用asp.net的webMethod

在vs2010中,用JQuery ajax调用asp.net 2.0的  webMethod 方法时,怎么都调不出来,原来和3.5 有点出入。

3.5中,无需特殊设置,可以直接用$.ajax调用在aspx.cs中,访问级别public,静态的,标记为【webmethod】的方法。

 

aspx.cs:

using System.Web.Services;
[WebMethod]
public static string PollCount()
{
    ……    return getResultHTML(ds2);

}


 

<div id="divAnswers" runat="server">
</div>

<script src="scripts/jquery-1.4.4.min.js" type="text/javascript"></script>
<script language="javascript" type="text/javascript">
    $(document).ready(function () {
        var imgPoll = new Image();
        imgPoll.src = 'style/red-bar.png';
        $.ajax(
            {
                type: "POST",
                contentType: "application/json",
                url: "voteresult.aspx/PollCount",
                data: "{}",
                dataType: "json",
                success: function (msg) 
                {
                    $("div[id$=divAnswers]").fadeOut("fast").html(msg.d).fadeIn("fast", function () { animateResults(); });
                }
            });
    });
    function animateResults() {
        $("div[id$=divAnswers] img").each(function () {
            var percentage = $(this).attr("val");
            $(this).css({ width: "0%" }).animate({ width: percentage }, 'slow');
        });
    }  
</script>
