Question

I make product my favourite with Javascript yes no window. When click yes button, product gets my favourite and refresh background page. I have MakeMyFavorite action in the controller, but it return same result every call.

public ActionResult MakeMyFavorite( int id )
{
   ....
   return RedirectToAction( "Details", "Product", product );
}

and Javascript:

<script language="JavaScript" type="text/javascript">
    function confirmFavorite() {
        if (confirm("Are you sure make favorite?")) {
            document.location.reload(true);
            return true;
        } else {
            return false;
        }
    } 
</script>

and link:

<a href="@Html.Action ( "MakeMyFavorite", "Product", new { id = item.ID } )" 
     onclick = "return confirmFavorite()"> Make Favorite </a> 

I use Make Favorite link in different places in the site (Details, Index and other views). When click link, product is favourite, page refresh, but always opens Details view.
I changed ActionResult with void in the controller, but never open, because, there is not return view.
How should I do, in different pages of site, when I click Make Favorite link, product is favourite, but background page not change? To stay current view. (Sorry for bad English)

Answer 1

You can do this

Make a JsonResult Action

Like

public JsonResult MakeMyFavorite(int id)
{
   ......
   string result = "favorite";
   return this.Json(result, JsonRequestBehavior.AllowGet);
}

Make your anchor tag like

<a href="#" id="myfav" onclick="confirmFavorite(@item.id);">Favorite</a>

and your jquery for handling this

<script type="text/javascript">
    function confirmFavorite (id) {
        if(confirm("Are you sure make favorite?")) {
           var data = { "id": id };
           $.getJSON("/Product/MakeMyFavorite", data, function (data) {
               //check your data here what it is returning
               if($.trim(data)=="favorite")
               {
                //Do what you want to do.
               }
           });
        }
     }

</script>
