Can't get simplest ASP.NET MVC3 form to post asynchronously using AJAX
I can't see why the following form performs a full postback instead of asynchronously using AJAX. Request.IsAjaxRequest() is always false. I think I've followed all the examples correctly. What am I doing wrong?
Here's the view:
@(Layout = null)
<!DOCTYPE html>
<html>
<head>
<title>Index</title>
<script src="../../Scripts/MicrosoftAjax.js" type="开发者_开发百科text/javascript"></script>
<script src="../../Scripts/MicrosoftMvcAjax.js" type="text/javascript"></script>
<script src="../../Scripts/MicrosoftMvcValidation.js" type="text/javascript"></script>
<script src="../../Scripts/jquery-1.4.4.js" type="text/javascript"></script>
</head>
<body>
<div>
<div id="update"></div>
@using(Ajax.BeginForm(new AjaxOptions { UpdateTargetId = "update" }))
{
<input type="submit" value="test" />
}
</div>
</body>
</html>
And here's the controller:
using System.Web.Mvc;
namespace TheHoges.Web.Controllers
{
public class TestController : Controller
{
public ActionResult Index()
{
if (Request.IsAjaxRequest())
{
// never gets here
return Content("it worked");
}
return View();
}
}
}
For reference:
AJAX and MVC 3
<script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>
Do you see this in you web.config?
<add key="UnobtrusiveJavaScriptEnabled" value="true"/>
If, yes, including the library above should solve your problem.
Just to be thorough I created a test page. Works peachy...
@{
ViewBag.Title = "Home Page";
}
@(Layout = null)
<!DOCTYPE html>
<html>
<head>
<title>Index</title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>
</head>
<body>
<div>
<div id="update">
</div>
@using(Ajax.BeginForm(new AjaxOptions { UpdateTargetId = "update" }))
{
<input type="submit" value="test" />
}
</div>
</body>
</html>
加载中,请稍侯......
