javascript - Google Maps directions mvcobject getting a individual step -

-

i using directionsservice directions via google maps javascript api. issue want individual steps , yet have them part of mvc object when click on them render on map default

directionsdisplay.setdirections(response);

does. code:

var directionsservice = new google.maps.directionsservice(); directionsdisplay.setmap(map);  var request = {         origin : a,         destination : b,         travelmode : google.maps.directionstravelmode.driving };  directionsservice.route(request, function(response, status) {      if (status == google.maps.directionsstatus.ok) {                 directionsdisplay.setdirections(response);           //instead of setting directions panel want            //set 1 panel , yet have link           //map above does.             }});

the idea must iterate on each leg of route, on each step in leg , render own html represent it. see following code (assumes have map, directionsdisplay, , directionsservice, , request defined):

directionsservice.route(request, function(response, status) {   // make sure directions request valid   if (status == google.maps.directionsstatus.ok) {     // give response directions display     directionsdisplay.setdirections(response);      // display route on map     directionsdisplay.setmap(map);      // grab result routes     var routeresult = response.routes[0];      // iterate on each leg of route     routeresult.legs.foreach(function(leg) {       // build html each step       var stephtml = '';       leg.steps.foreach(function(step) {         stephtml += '<div class="directionstep">'+                   '<div>'+step.instructions+'</div>'+                   '<div class="grey">'+step.distance.text+' ('+step.duration.text+')'+'</div>'+                 '</div>';       });        // put step html somewhere       $('.steps').append(stephtml);     });   } });

then, listen clicks on individual steps , whatever need in response.
