Question

I am trying to make a MVC website with Ajax call. I have no problem using directly jquery, but when i use @Ajax.ActionLink, i don’t get the result i want.
Here is my view:

    <script type="text/javascript">
        function deleteComment(id) {
            $.post(
                "/Role/AjaxTest",
                //{ id: id }, 

                function (data) {
                    $("#testtarget").html(data);               
                });
         }
    </script>


    <script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.min.js")" type="text/javascript"></script>
    <h2>TITLE</h2>
    <p>
 @Ajax.ActionLink("Ajax Test", "AjaxTest", "Role", new AjaxOptions{UpdateTargetId="testtarget",HttpMethod = "Get" , InsertionMode = InsertionMode.Replace }) 
    </p>
    <table>    
    @foreach (var item in Model) {
        <tr>
            <td>
                @Html.DisplayFor(modelItem => item.RoleName)
            </td>
            <td>
              <a onclick="deleteComment('@item.RoleId'); return false;" href="#">Delete</a>
                @Html.ActionLink("Delete", "Delete", new { id=item.RoleId })

            </td>
        </tr>
    }
    </table>
    <div id="testtarget">Test Div</div>

and here is my Controler data:

public string AjaxTest()
{
    return "Some random text";
}

My Call on Jquery works perfectly and text appears in the div, but my actionlink just redirects me to : localhost/Role/AjaxTest so i just have the message in a bank browser.

Any idea what’s wrong here?

Thanks a lot in advance!

Make sure you have added the jquery.unobtrusive-ajax.js script to your page:

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

or if you are using bundles (which is the recommended approach) make sure that you have included a bundle containing this script. For example when you create a new ASP.NET MVC 4 project using the Internet Template that would be the ~/bundles/jqueryval bundle:

bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
    "~/Scripts/jquery.unobtrusive*",
    "~/Scripts/jquery.validate*")
);

So make sure it is included in your view after the jquery bundle:

@Scripts.Render("~/bundles/jquery")
@Scripts.Render("~/bundles/jqueryval")

Or just combine them into a single bundle. It will all depend on your requirements and whether you need unobtrusive jquery validation support or not.

I would also recommend you to have your controller action return ActionResult and not string:

public ActionResult AjaxTest()
{
    return Content("Some random text");
}
