我想知道,如果点子被点击,我是否可以在控制器中采用某种方法。
我有以下看法:home
,在装上该观点时,该观点在控制器中援引Ind
。 我有<代码>Button(超文本或ASP.NET) ,称为<代码>LoadData。 当我点击 but子时,我需要把一些数据装上所谓的<代码>。 Home .
我如何这样做?

如果希望用美国宇宙航空研究开发机构的形式提供数据,就必须让JQuery或Java式读物公司参与。 但最简单的形式是:
<% Html.BeginForm("Action", "Controller"); %>
<!--Form values in here-->
<input type="submit" />
<% Html.EndForm(); %>
将援引你的行动方法并援引背后。 该系统中有一个自动协调机制。 Web.Mvc.Ajax, 用AjaxForm和AJAX备选办法做背后yn,很容易安装。 我倾向于亲自使用JQuery。
HTH.
为了利用一个简单员额来做到这一点,你刚刚需要把控制器方法存在的URL上调。
例如,遵循你全球确定的标准路线。
如果你在称为“LoadData”的家库勒班内有控制器方法,那么你可以使用URL:
/Home/Load 数据
这就是你加入以下表格的URL:action/code>属性。
你们也可以利用美国宇宙航空研究开发机构的请求,将数据输入你重新接下去的同一页,而没有任何回击。
你们可以做这样的事情:
$( #myForm ).submit(function() {
$.post(
this.action,{params},
function(data){ // do something with return info }
}
您界定了两种行动,一种是表明空洞的观点,另一种是把观点列入清单:
public ViewResult Empty()
{
var products = productsRepository.Products.Where(x => x.ProductID == -1);
return View();
}
并且:
public ViewResult ListAll()
{
var products = productsRepository.Products;
return View("Empty", products);
}
以及您的看法

<td>

</td>
</tr>

兹致函主计长如下。
public class HomeController : Controller
{
public ActionResult Index()
{
return View();
}
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult FetchData()
{
return Content("Some data...");
}
}
并要求采取下列行动。
<% using (Ajax.BeginForm("FetchData", new AjaxOptions() { UpdateTargetId = "ContentPlaceHolder", HttpMethod = "Post" }))
{ %>
<div id="ContentPlaceHolder"></div>
<input type="submit" value="Fetch Data" />
<% } %>
