  • Give the alert or store in another variable in javascript on oncomplete of action function Commented Oct 1, 2014 at 19:55
  • Do you have an associated controller as well? You could place them in a variable then and pass that variable to the javascript.

This is the simplest way to achieve it

You can assign the the error Message to alertMsg to serve your purpose.

Page:

<apex:page controller="Js_Alert" >
              <script> 
                    {!alertMsg}
              </script>
    </apex:page>

Controller :

public class Js_Alert {

public string alertMsg{get;set;}

public SE_Js_Alert()
{

    alertMsg = 'alert(\'Error Msg\'); ';

}
}
