How do I redraw a google maps marker on click? -


i have google map set of map markers. chose draw map markers function called pinsymbol() - instead of using default image.

i want change color of pin when clicked, can't update. current code can change property of icon, can see console.log(marker), won't update color on map.

question: how redraw icon on click?

this code.

// go through restaurants , facebook info, // create marker each one.    restaurants.foreach(function(restaurant){     getfacebookinfo(restaurant);   }); // end foreach loop   // data facebook graph api , create marker   function getfacebookinfo(restaurant){     $.ajax({       url : '/restaurants/' + restaurant.id,       type : 'get',       datatype:'json',       success : function(data) {           restaurant.about = data.about;           createmarker(restaurant);       },       error : function(request, error) {         console.log(error);         alert("we're having trouble getting restaurant's info facebook. " +         "please check internet connection , try refreshing page.")       }     });   }  // create marker on map location   function createmarker(restaurant){   var position = restaurant.location;   var infowindow = new google.maps.infowindow({   maxwidth: 200   });     restaurant.marker = new google.maps.marker({      position: position,      map: map,      icon: pinsymbol('#cd212a', '#cd212a'),      name: restaurant.name,      id: restaurant.id,      about: restaurant.about,      animation: google.maps.animation.drop    });     // push marker array of markers    markers.push(restaurant.marker);     // call populateinfowindow function    populateinfowindow(restaurant.marker, infowindow);     // add infowindow property restaurant    // makes available use outside function.    restaurant.infowindow = infowindow;

this i'm stuck: 

   // open infowindow when marker clicked , change color    restaurant.marker.addlistener('click', function(){      this.icon = pinsymbol('#eed4d9', '#eed4d9');      console.log(restaurant.marker);      infowindow.open(map, this);    });  }

pinsymbol function 

// create pin google map marker   function pinsymbol(color, strokecolor) {     return {         path: 'm 0,0 c -2,-20 -10,-22 -10,-30 10,10 0 1,1 10,-30 c 10,-22 2,-20 0,0 z',         fillcolor: color,         fillopacity: 1,         strokecolor: strokecolor,         strokeweight: 1,         scale: 1,         labelorigin: new google.maps.point(0,-29)     };   }

there no (documented) .icon property of marker. don't use it. use documented .seticon method:

// open infowindow when marker clicked , change color restaurant.marker.addlistener('click', function() {   this.seticon(pinsymbol('#eed4d9', '#eed4d9'));   console.log(restaurant.marker);   infowindow.open(map, this); });

code snippet:

var geocoder;  var map;  var markers = [];    function initialize() {    map = new google.maps.map(      document.getelementbyid("map_canvas"), {        center: new google.maps.latlng(37.4419, -122.1419),        zoom: 13,        maptypeid: google.maps.maptypeid.roadmap      });    createmarker({      name: "center",      id: 2,      about: "",      location: {        lat: 37.4419,        lng: -122.1419      }    });  }  google.maps.event.adddomlistener(window, "load", initialize);  // create marker on map location  function createmarker(restaurant) {    var position = restaurant.location;    var infowindow = new google.maps.infowindow({      maxwidth: 200    });      restaurant.marker = new google.maps.marker({      position: position,      map: map,      icon: pinsymbol('#cd212a', '#cd212a'),      name: restaurant.name,      id: restaurant.id,      about: restaurant.about,      animation: google.maps.animation.drop    });      // push marker array of markers    markers.push(restaurant.marker);      // call populateinfowindow function    populateinfowindow(restaurant.marker, infowindow);      // add infowindow property restaurant    // makes available use outside function.    restaurant.infowindow = infowindow;      // open infowindow when marker clicked , change color    restaurant.marker.addlistener('click', function() {      if (this.geticon().fillcolor != "#eed4d9") {        this.seticon(pinsymbol('#eed4d9', '#eed4d9'));      } else {        this.seticon(pinsymbol('#cd212a', '#cd212a'));      }      console.log(restaurant.marker);      infowindow.open(map, this);    });  }    // create pin google map marker  function pinsymbol(color, strokecolor) {    return {      path: 'm 0,0 c -2,-20 -10,-22 -10,-30 10,10 0 1,1 10,-30 c 10,-22 2,-20 0,0 z',      fillcolor: color,      fillopacity: 1,      strokecolor: strokecolor,      strokeweight: 1,      scale: 1,      labelorigin: new google.maps.point(0, -29)    };  }    function populateinfowindow(marker, infowindow) {    infowindow.setcontent("content");  };
html,  body,  #map_canvas {    height: 100%;    width: 100%;    margin: 0px;    padding: 0px  }
