ASP.NET MVC 4 - Ajax.ActionLink calls the method multiple times

Question

This is the part of code in

<script type="text/javascript" src="~/scripts/jquery.unobtrusive-ajax.js"></script> Ajax.ActionLink("Yes", "Delete", "Notes", new { id = item.NoteId }, new AjaxOptions { HttpMethod = "POST", OnComplete = "javascript:void(0);" }, new { id = item.NoteId, @class = "yes" });

Upon clicking it is supposed to call the following action:

 [HttpPost] public bool Delete(int id) { Notes notes = db.Notes.Find(id); db.Notes.Remove(notes); db.SaveChanges(); return true; }

And it does - the note gets deleted. But the method is called 5 or 8 more times for some reason.

 POST http://localhost:57904/Notes/Delete/41 500 (Internal Server Error) jquery-1.8.2.min.js:2 POST http://localhost:57904/Notes/Delete/41 500 (Internal Server Error) jquery-1.8.2.js:8416 POST http://localhost:57904/Notes/Delete/41 500 (Internal Server Error) jquery-1.8.2.min.js:2 POST http://localhost:57904/Notes/Delete/41 500 (Internal Server Error) jquery-1.8.2.js:8416

What could be the cause of the extra calls?

This line was the cause:

<script type="text/javascript" src="~/scripts/jquery.unobtrusive-ajax.js"></script>

I actually put it inside a "foreach" loop, causing it to be included multiple times. Once I moved it outside of that loop, the problem was fixed.

Note to self: you only include once.

oh my god thank you. i kept including it through @{ Layout = ... } which made it crash every second time i did a partial reload

Ajax.ActionLink("Yes", "Delete", "Notes", new { id = item.NoteId }, new AjaxOptions { HttpMethod = "POST", OnComplete = "javascript:void(0);" }, new { id = item.NoteId, @class = "yes" });

change this to

Ajax.ActionLink("Yes", "Delete", "Notes", new { id = item.NoteId }, new AjaxOptions { HttpMethod = "POST", OnComplete = "javascript:void(0);" }, new { @class = "yes" });
