asp.net mvc - Executing JavaScript from an Action that returns ActionResult -


I am trying to implement the error handling system in my MVC project. I am looking for a way to show the error message to the user on the same page. I have tried -

- However, this does not work because I am calling the action through the ActionLink and not Ajax. I can not call it through Ajax because the error may load when the page loads for the first time.

- This does not show a warning

I do this in a catch block - 

  Public Action Index () {Try {// Some that generate an exception} Cache (Exception E) {// Show a warning with error via JS}}   
 Is there a way to execute javascript? An error to the user without using an Ajax call?   
 
 
 You can do something like  
  hold (exception e) {ViewBag.Error = "Error:" + E. Toasting (); } See Return ();   
 In your view  
  & lt;% if (ViewBag.Error! = Null) {%> & Lt; Script type = "text / javascript" & gt; Warning ('<% = ViewBag.Error%>';); & Lt; / Script & gt; & Lt;%}% & gt;
