列表主页Action内容:

public ActionResult HelpList()
{
Entity.Commons.VPredication vp = new Entity.Commons.VPredication();
Entity.Commons.PagingParam pp = new Entity.Commons.PagingParam(1, 10);
Entity.PagedList<Entity.HelpDocument> list = _HelpDocumentServices.GetHelpDocument(vp, pp);
List<Entity.HelpCategory> clist = _HelpDocumentServices.GetAllCatetories();
clist.Insert(0, new Entity.HelpCategory() { HelpCategoryID = "", CategoryName = "选择类别" });
ViewData["Category"] = clist;
return View(list);
}
列表用户控制页Action内容:

public ActionResult PageHelp(int? pi, string title, string cid)
{
Entity.Commons.VPredication vp = new Entity.Commons.VPredication();
Entity.Commons.PagingParam pp = new Entity.Commons.PagingParam(pi ?? 1, 10);
if (!string.IsNullOrEmpty(title))
vp.AddItem("Title", title);
if (!string.IsNullOrEmpty(cid))
vp.AddItem("HelpCategoryID", cid);
Entity.PagedList<Entity.HelpDocument> list = _HelpDocumentServices.GetHelpDocument(vp, pp);
list.AddParameters = new System.Collections.Specialized.NameValueCollection();
list.AddParameters.Add("title", title);
list.AddParameters.Add("cid", cid);
return PartialView("LelpItemList", list);
}
ASPX文件:

<script type="text/javascript">
$(function() {
$('#search_btn').click(function() {
var title = $('#Title').val();
var cid = $('#CategoryList').val();
$.ajax({
type: "POST",
url: "/Help/PageHelp",
data: "pi=1&title=" + title + "&cid=" + cid,
success: function(data) {
$('#helpitem_div').html(data);
}
});
})
})

</script>
