How can I call a controller method from VisualForce page without any onclick event happening?
My VisualForce page would be like

<apex:page standardController=Account> 



    <script>

     /* Here i need to call a controller class with out any onclick event. It should load by itselef */



    </script>



</apex:page>

and my controller class will be like

public class OrderPadController {

    /* this will be the constructor */



    public PageReference openPage() {

         PageReference newpage = new Pagereference('/apex'+'/pagetoopen'+'?aid='+a.id); 

         openorderpadembed.setRedirect(false); 

         return openorderpadembed;      

    }

From my VisualForce page I need to call the method openPage().

Please help me out

You can use JavaScript Remoting for Apex Controllers in the following manner:

<apex:page standardController=Account extensions=OrderPadController>

    <script src=//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js></script>

    <script>

      window.$j = jQuery.noConflict();

      $j( document ).ready(function() {

        OrderPadController.openPage(function(result, event){



            console.log(result);

            window.open(result,_self);



        });

      });



    </script>

</apex:page>

public class OrderPadController {

    //



    @remoteAction

    public  PageReference openPage() {

        PageReference newpage = NEW Pagereference('/apex' + '/pagetoopen' + '?aid=' + a.id);

        openorderpadembed.setRedirect(false);

        return openorderpadembed;

    }

}
