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.
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); "
You can call JavaScript as well as content methods
public ActionResult Java_Script(){
return JavaScript("Message");
}
