How to open a popup window when a marker is clicked from a route service?

Question

UPDATE
when I click the green marker, it displays the location.can address can I change it?

LAST CHANGES:
Can a pop-up window click a marker from a route service?
or try another way, as soon as you hide the marker from the route service (green marker) and display only the red marker (hide only the green marker, not the route)? Is this a good way?

If this is not possible, suggest some alternative ideas.

OLDER:

I have a marker of two types on a google map. The red marker is a normal marker that represents location.and the green marker is a route marker (it represents a lot of waypoints on the map).
I am changing the infowindow with textbox.which is open on the red click mark.

In fact, I'm trying to do this, first I put some markers on a Google map, then draw a route between these markers. This is done. Immediately on the green marker, a single pop-up window appears in which the user enters a price, and then click the button. Then I got this value and saved it in the database.
The problem is this:

code is:

    <script type="text/javascript">
      var markerarray=new Array(); 
      //for way points
      var waypts=[];
      //array in json format for placing multiple marker
      var locations = <?php echo json_encode($lat1);?>;

      var map = new google.maps.Map(document.getElementById('map'), {
          zoom: 11,
          center: new google.maps.LatLng(23.0171240, 72.5330533),
          mapTypeId: google.maps.MapTypeId.ROADMAP

      var infowindow = new google.maps.InfoWindow();

      //push value into way points

      //create array for polyline
      markerarray[i] = marker.getPosition();//(Array(locations[i][5], locations[i][6]));

      google.maps.event.addListener(marker, 'click', (function(marker, i) {
        return function() {
            var data='<div style="height:150px !important"><table><tr><td>Enter Price</td></tr><tr><td><input type="text" name="prc" id="prc" /></td></tr></table></div>';
            infowindow.setContent(data);
            infowindow.open(map, marker);
         }
        })(marker, i));
      }

//close here your set interval
