i trying migrate rails 3 , ujs jquery

now old code this:

page['contact_detail_data'].visual_effect :scrollto,:duration => 0.5,:offset => -30

now in jquery think must use animate

so thought of :

page['contact_detail_data'].animate :scrollto,:duration => 0.5,:offset => -30

but unsure of how give parameters can please guide me ?

you can use :

page.call("anim_up_down","certification_#{params[:index]}",30,500 )

and in javascript

function anim_up_down(ele,extraoffset,duration){      $('html,body').animate({scrolltop: $('#'+ele).offset().top-extraoffset},duration)  }
