Example code: In an MVC 5 project in Visual Studio, I have set up the following controller and views:
Controller
TestController.cs
public class TestController : BaseController
{
public ActionResult Index()
{
return View("Index");
}
public PartialViewResult MyPartialView1()
{
return PartialView("PartialView1");
}
public PartialViewResult MyPartialView2()
{
return PartialView("PartialView2");
}
}
Views
Index.cshtml
@{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<script src="@Url.Content("~/Scripts/jquery-2.1.1.min.js")"></script>
<script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.min.js")"></script>
</head>
<body>
<h1>Testing Unobtrusive AJAX</h1>
@Ajax.ActionLink("Partial 1", "MyPartialView1", "Test",
new AjaxOptions() { UpdateTargetId = "contentShouldLoadHere", InsertionMode = InsertionMode.Replace })
|
@Ajax.ActionLink("Partial 2", "MyPartialView2", "Test",
new AjaxOptions() { UpdateTargetId = "contentShouldLoadHere", InsertionMode = InsertionMode.Replace })
<div id="contentShouldLoadHere">
<p>This will get replaced.</p>
</div>
</body>
</html>
PartialView1.cshtml
<h1>Test 1</h1>
PartialView2.cshtml
<h1>Test 2</h1>
Question
If I have understood correctly, clicking "Partial 1" should load the contents of "PartialView1" into the HTML element with an ID of "contentShouldLoadHere". Instead, clicking "Partial 1" causes a normal page load of the MyPartialView1 action (~/Test/MyPartialView1), and in the Chrome dev tools console I get the following JavaScript error:
Uncaught ReferenceError: Sys is undefined
Does anyone know why this is, and how I can fix it?
Notes - I have confirmed via Chrome Dev Tools that both scripts are being correctly loaded. - The HTML for the link generated by the @Ajax helper is:
<a href="/Test/MyPartialView1" onclick="Sys.Mvc.AsyncHyperlink.handleClick(this, new Sys.UI.DomEvent(event), { insertionMode: Sys.Mvc.InsertionMode.replace, updateTargetId: 'contentShouldLoadHere' });">Partial 1</a>
