javascript - Adding InfoWindow on Google directions route -

i trying add infowindow directions route,there lots of examples out there adding infowindow on event listener on marker how can move infowindow show on actual planned route 1 marker another. tried ask question before no response (infowindow on directions route), anyway did lot of googling , found 1 question similar again there no response that. tried infowindow.open(map,this) on event on marker in callback open infowindow on marker position..its want show duration , distance similar google..something in attached image

var infowindow2 = new google.maps.infowindow(); distanceservice.getdistancematrix(distancerequest, function (response, status) {     if (status == "ok") {       infowindow2.setcontent(response.rows[0].elements[0].distance.text + "<br>" + response.rows[0].elements[0].duration.text + " ")     }     else {       alert("error: " + status)     }   }) infowindow2.open(map, this); 

to find position on route , put infowindow there, parse route (the details described in documentation). location along route , call setposition method of infowindow position.

function calcroute(start, end) {   var request = {       origin:start,       destination:end,       travelmode: google.maps.directionstravelmode.driving   };   directionsservice.route(request, function(response, status) {     if (status == google.maps.directionsstatus.ok) {       directionsdisplay.setdirections(response);       var step = 1;       var infowindow2 = new google.maps.infowindow();       infowindow2.setcontent(response.routes[0].legs[0].steps[step].distance.text + "<br>" + response.routes[0].legs[0].steps[step].duration.text + " ");       infowindow2.setposition(response.routes[0].legs[0].steps[step].end_location);       infowindow2.open(map);     }   }); }

code snippet:

var directionsdisplay;  var directionsservice = new google.maps.directionsservice();  var map;    function initialize() {    directionsdisplay = new google.maps.directionsrenderer();    var chicago = new google.maps.latlng(41.850033, -87.6500523);      var mapoptions = {      zoom: 7,      maptypeid: google.maps.maptypeid.roadmap,      center: chicago    }    map = new google.maps.map(document.getelementbyid('map-canvas'), mapoptions);    directionsdisplay.setmap(map);    calcroute("67 windmill hill, allesley, coventry cv5 9fr, uk", "26 rosaville crescent, allesley, coventry cv5 9bp, uk");  }    function calcroute(start, end) {    var request = {      origin: start,      destination: end,      travelmode: google.maps.directionstravelmode.driving    };    directionsservice.route(request, function(response, status) {      if (status == google.maps.directionsstatus.ok) {        directionsdisplay.setdirections(response);        var step = 1;        var infowindow2 = new google.maps.infowindow();        infowindow2.setcontent(response.routes[0].legs[0].steps[step].distance.text + "<br>" + response.routes[0].legs[0].steps[step].duration.text + " ");        infowindow2.setposition(response.routes[0].legs[0].steps[step].end_location);        infowindow2.open(map);      }    });  }    google.maps.event.adddomlistener(window, 'load', initialize);
