javascript - Adding multiple markers to Google Map -


i'm looking add markers each business listed google map v3 api on page in top right hand corner.

i'm not sure how multiple postcodes, 1 use on individual business pages use urlencode dynamic postcodes stored in database.

here's code use individual pages:

<script src="http://maps.googleapis.com/maps/api/js?q=london&key=aizasybapedyfbbnwjtvt8w3ubom34y7g6vk69a&sensor=false"></script>      var map;     function initialize() {       var mapoptions = {         zoom: 15,         center: new google.maps.latlng(51.511214,-0.119824),         maptypeid: google.maps.maptypeid.roadmap       };       var geolocate = function(address, callback) {             $.ajax({                     url: "http://maps.googleapis.com/maps/api/geocode/json",                     data: {                         "sensor": true,                         "address": address                     },                     datatype: "json",                     success: function(d) {                         if (d.status == "zero_results") callback(false);                         if (d.results && d.results[0] && d.results[0].geometry) {                             callback({                                 "ne": d.results[0].geometry.bounds.northeast,                                 "sw": d.results[0].geometry.bounds.southwest,                                 "center": d.results[0].geometry.location                             });                         }                         else callback(false);                     }                 });       };       map = new google.maps.map(document.getelementbyid('map-canvas'),           mapoptions);       geolocate("<%=server.urlencode(""&rsadvert("contactpostcode"))%>", function(c) {             map.setcenter(new google.maps.latlng(c.center.lat, c.center.lng));      });     }     google.maps.event.adddomlistener(window, 'load', initialize);  $('#mymodal').on('shown', function () {   google.maps.event.trigger(map, 'resize'); })

the postcodes page generated in asp:

    if rsdb_ads("contactpostcode") <> ""         strtemphtml = "[contactpostcode]"         strdb_advertitem = replace(strdb_advertitem, "<!--contactpostcode-->", strtemphtml)     else         strdb_advertitem = replace(strdb_advertitem, "<!--contactpostcode-->", "")     end if

hoping can help..

just start, here how manage multiple markers. (copy & paste code html file , works ...) can adapt code writing out locations db etc. via classic asp:

    <!doctype html>     <html>     <head>       <meta http-equiv="content-type" content="text/html; charset=utf-8" />       <title>google maps multiple markers</title>       <script src="http://maps.google.com/maps/api/js?sensor=false"               type="text/javascript"></script>     </head>     <body>       <div id="map" style="width: 1000px; height: 1000px;"></div>        <script type="text/javascript">         var locations = [           ['stadtbibliothek zanklhof', 47.06976, 15.43154, 1],           ['stadtbibliothek diemediathek', 47.06975, 15.43116, 2],           ['stadtbibliothek gösting', 47.09399, 15.40548, 3],           ['stadtbibliothek graz west', 47.06993, 15.40727, 4],           ['stadtbibliothek graz ost', 47.06934, 15.45888, 5],           ['stadtbibliothek graz süd', 47.04572, 15.43234, 6],           ['stadtbibliothek graz nord', 47.08350, 15.43212, 7],           ['stadtbibliothek andritz', 47.10280, 15.42137, 8]         ];          var map = new google.maps.map(document.getelementbyid('map'), {           zoom: 13,           center: new google.maps.latlng(47.071876, 15.441456),           maptypeid: google.maps.maptypeid.roadmap         });          var infowindow = new google.maps.infowindow();          var marker, i;          (i = 0; < locations.length; i++) {           marker = new google.maps.marker({             position: new google.maps.latlng(locations[i][1], locations[i][2]),             map: map           });            google.maps.event.addlistener(marker, 'click', (function(marker, i) {             return function() {               infowindow.setcontent(locations[i][0]);               infowindow.open(map, marker);             }           })(marker, i));         }       </script>     </body>     </html>
