You CAN call it directly if you are using ajax.

Page A -> Ajax -> Controller -> Return javascript which invokes a method in Page A

    public ActionResult MyAjax(string message)
    {
        return JavaScript(string.Format("methodInPageA('{0}');", message.Replace("'", "\\'")));
    }

It might work without ajax too, but I haven't tried that.

  • WHAT is not working? How do you invoke the controller method? What result do you get? I'm using this solution myself in different projects. As I said: It might only work with ajax. – jgauffin Nov 26 '10 at 12:04

You wont be able to call it directly you will have to call the javascript function onLoad document or other page event (like button click or something)

  • in mvc, onload is not working that i know but it's one class file only so it doesn't work.Here i have " ScriptManager.RegisterStartupScript(@@@@@@,this.GetType(),"setMenuItem","setMenuItem();",true); " – Hitesh Prajapati Nov 26 '10 at 11:06

You can call JavaScript as well as content methods

 public ActionResult Java_Script(){
      return JavaScript("Message");
 }
