<script type="text/javascript"> $Content = $("#MovieListing");//填充父容器 $PIndex = $("#pIndex");// $(function () { $("#btnShowMore").click(function () { ShowMore(); }); ShowMore(); }); function ShowMore() { $.ajax({ url: "Listing", data: { pIndex: $PIndex.val() }, success: function (data) { $Content.append(data); $PIndex.val(+($PIndex.val()) + 1); } }); } </script>
前台主界面里,准备好一个数据填充容器,一个临时保存当前获取第几页的容器,
Controller里写个返回分布视图的Action,用到了了两个获取数据的方法,下面会贴出来的,别急。
public ActionResult Listing(int pIndex) { int pageCount = 5;//每次获取的条数 if (pageCount * pIndex > zService.MovieService().Length())//数量越界 { return null; } var resault = zService.MovieService().Filter(pIndex, pageCount); return PartialView(resault); }
返回数据的代码,就随便写个Service,里面的两个方法:
public class MovieService { private MovieDBContext db = new MovieDBContext(); public IEnumerable<MovieInfo> Filter(int pIndex, int count) { return db.Movies.OrderBy(d => d.ID).Skip(pIndex * count).Take(count).ToList(); } public int Length() { return db.Movies.Count(); } }
