当我点击Ajax.ActionLink是叫我的控制器的两倍。

＆LT; TD ID = @ tdTag＆GT;    @ Ajax.ActionLink（LL-+ item.getProjectAbbreviation（item.projectID.Value）+ - + item.prjLessonID，详细信息，                     新{ID = item.lessonID}，                     新AjaxOptions                         {                           HttpMethod =POST                           UpdateTargetId =细节，                           InsertionMode = InsertionMode.InsertAfter，                           的onSuccess =showDetails（）                          }）

我的控制器看起来像这样...

公众的ActionResult详细信息（INT ID）     {         使用（LLDataContext storeDB =新LLDataContext（））         {             VAR教训=（从升的storeDB.lessons                           其中，l.lessonID == ID                           选择L）.SingleOrDefault（）;             返回PartialView（课）;         }     }

解决方案

我只是跑在这个同样的问题，我发现我不得不装两次jquery.unobtrusive-ajax.js。我删除了第二个实例，一切工作正常。要看到这个动作，只是将它加入三次，并创建一个@ Ajax.ActionLink（...）与确认AjaxOption。你会得到证实多次。

＆LT;脚本SRC =@ Url.Content（〜/脚本/ jquery.unobtrusive-ajax.js）类型=文/ JavaScript的＆GT;＆LT; /脚本＆GT;

When I click on Ajax.ActionLink it is calling my controller twice.

<td id = @tdTag> @Ajax.ActionLink("LL-" + item.getProjectAbbreviation(item.projectID.Value) + "-" + item.prjLessonID, "Details", new { id = item.lessonID }, new AjaxOptions { HttpMethod = "POST", UpdateTargetId = "details", InsertionMode = InsertionMode.InsertAfter , OnSuccess = "showDetails()" })

My Controller looks like this...

public ActionResult Details(int id) { using (LLDataContext storeDB = new LLDataContext()) { var lesson = (from l in storeDB.lessons where l.lessonID == id select l).SingleOrDefault(); return PartialView(lesson); } }

解决方案

I just ran in this same issue and I found that I had "jquery.unobtrusive-ajax.js" loaded twice. I removed the second instance and all is working well. To see this in action, just add it three times and create an @Ajax.ActionLink(...) with an Confirm AjaxOption. You will get confirmed multiple times.

<script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>
