Opening a new browser tab from rails action in the controller

so i have a Exam controller. Now the the file for it has a jqgrid (index.html.erb )on it. One clicks on the grid row and i have set upped the javascript for handling the event. it looks like

<script type= "text/javascript">
function handleSelection(id) {
    <%=  
    remote_function :url => render_exam_exams_path,:with => "'id='+id" 
    %>
}
</script>

now the the method i was just testing as follows

def render_exam
    @exams = Exam.find(params[:id])
    #either
    #redirect_to home_index_path
    #or open this in new browser tab        
    #render :action => "render_exam"
end

and I have a view called render_exam as well. Now i have checked the server logs and all, everything works fine even the render_exam is generated as i could see that in chrome developer plugin. Now the problem is i want either

  1. the controller action render_exam to open up a new tab and render render_exam view as it seems to be happening remotely (generating render_exam view and all)without changing the jqgrid page. But I couldn't find a way to open up a new browser tab to render the render_exam action view from the render_exam action itself rather than happening behind the scene. or
  2. have the jqGrid (or index view) page redirected to the render_exam view. Now the problem here was the redirect_to action doesn't work in the view as it is supposed to be controller method. So i can't say.
<script type= "text/javascript">
function handleSelection(id) {
    <%= redirect_to :action => render_exam_exams_path, :with => "'id='+id"  %>
}
</script>

otherwise the problem would have been solved. Any help is appreciated thanks

First, you can't redirect and render in the same action since there's only one response per action. Second opening a new tab is a client side feature (controlled by your browser), you need to use something like ""target=_blank in your link which will open a new browser which in turn will request a page (render_exam_exams_path in your case) from the server.
