mvc 使用jQuery实现查询问题

Question

在页面中使用AjaxPager实现页面绑定，用$.ajax做参数传递时，如果返回的参数页数大于1，就会出现问题，提示AjaxPager有个key的值为null。但是换成$.post传递参数时，就不会出现类似问题，那位大侠帮忙看下为什么。

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<PagedList<ResouceManage.Models.Stat.ResourceUseForm>>" %>
<%@ Import Namespace="Webdiyer.WebControls.Mvc" %>
<div id="dvListRs">
    <script type="text/javascript">
    var pageindex_p74 =<%= ViewData["pageindexRs"]==null?"0":ViewData["pageindexRs"].ToString()%>; 
    </script>
    <div style="clear: both">
    </div>
     <div>
          <%=Html.AjaxPager(Model, new PagerOptions
        {
            ContainerTagName = "span",
            FirstPageText = "首页",
            LastPageText = "尾页",
            PrevPageText = "上一页",
            NextPageText = "下一页",
            PageIndexParameterName = "id",
            AlwaysShowFirstLastPageNumber = true,
            HorizontalAlign = "right",
            NumericPagerItemWrapperFormatString = "<span class=\"cpb\">{0}</span>",
            NavigationPagerItemWrapperFormatString = "<span class=\"ppb\">{0}</span>"
        }, new AjaxOptions() { UpdateTargetId = "dvList",OnBegin = "AjaxGetDataStart", OnComplete = "AjaxStop" }, new { Style = "float:right;width:40%;" })%>
        </div>
