我有一个在我的主页 > index.cshtml 中使用分页的对象列表。当用户单击对象的每个页面时,我只想刷新页面的该部分,而不是其他任何内容。我将如何做到这一点?
理想情况下,我想使用异步方法和 ControllerActions ......
控制器 > HomeController.cs
public ViewResult Index(int page = 1) {
ProductsListViewModel viewModel = new ProductsListViewModel {
Products = repository.Products
.OrderBy(p => p.ProductID)
.Skip((page - 1) * PageSize)
.Take(PageSize),
PagingInfo = new PagingInfo {
CurrentPage = page,
ItemsPerPage = PageSize,
TotalItems = repository.Products.Count()
}
};
return View(viewModel);
}
首页 > 索引.cshtml:
@model SportsStore.WebUI.Models.ProductsListViewModel
@{
ViewBag.Title = "Products";
}
@foreach (var p in Model.Products) {
<div class="item">
<h3>@p.Name</h3>
@p.Description
<h4>@p.Price.ToString("c")</h4>
</div>
}
<div class="pager">
@Html.PageLinks(Model.PagingInfo, x => Url.Action("List", new {page = x}))
</div>
HtmlHelper > PagingHelper.cs
namespace SportsStore.WebUI.HtmlHelpers {
public static class PagingHelpers {
public static MvcHtmlString PageLinks(this HtmlHelper html,
PagingInfo pagingInfo,
Func<int, string> pageUrl) {
StringBuilder result = new StringBuilder();
for (int i = 1; i <= pagingInfo.TotalPages; i++) {
TagBuilder tag = new TagBuilder("a"); // Construct an <a> tag
tag.MergeAttribute("href", pageUrl(i));
tag.InnerHtml = i.ToString();
if (i == pagingInfo.CurrentPage)
tag.AddCssClass("selected");
result.Append(tag.ToString());
}
return MvcHtmlString.Create(result.ToString());
}
}
}
