    <script type="text/javascript">         var delay = 100;         var infowindow = new google.maps.infowindow();         var latlng = new google.maps.latlng(21.0000, 78.0000);         var mapoptions = {             zoom: 5,             center: latlng,             maptypeid: google.maps.maptypeid.roadmap         }         var geocoder = new google.maps.geocoder();         var map = new google.maps.map(document.getelementbyid("map_canvas"), mapoptions);         var bounds = new google.maps.latlngbounds();          function geocodeaddress(address, next) {             geocoder.geocode({address:address}, function (results,status){                 if (status == google.maps.geocoderstatus.ok) {                     var p = results[0].geometry.location;                     var lat=p.lat();                     var lng=p.lng();                     createmarker(address,lat,lng);                 }else {                     if (status == google.maps.geocoderstatus.over_query_limit) {                         nextaddress--;                         delay++;                     } else {}                 }                 next();             });         }          function createmarker(add,lat,lng) {             var contentstring = add;             var marker = new google.maps.marker({                 position: new google.maps.latlng(lat,lng),                 map: map             });              google.maps.event.addlistener(marker, 'click', function() {                 infowindow.setcontent(contentstring);                 infowindow.open(map,marker);             });              bounds.extend(marker.position);          }          <?php             global $wpdb;             $results = $wpdb->get_results("select * $wpdb->postmeta meta_value = 'canada'");             $num_rows = $wpdb->num_rows;         ?>             var locations = [             <?php foreach ($results $doc_meta_data) {                 echo "'";// . $doc_meta_data->meta_id;                 echo get_post_meta($doc_meta_data->post_id, 'address', true).",";                 echo get_post_meta($doc_meta_data->post_id, 'state', true).",";                 echo get_post_meta($doc_meta_data->post_id, 'country', true);                 echo "',";             }?>             ];              var nextaddress = 0;                 function thenext() {                     if (nextaddress < locations.length) {                         settimeout('geocodeaddress("'+locations[nextaddress]+'",thenext)', delay);                         nextaddress++;                     } else {                         map.fitbounds(bounds);                     }                 }             thenext();     </script>

how can add make each markers info dynamic ie, should come admin panel. url:http://intigateqatar.com/ozone/find-a-doc/

you need create infowindow in createmarker() function in order infowindows unique each marker:

function createmarker(add,lat,lng) {     var contentstring = add;     var marker = new google.maps.marker({        position: new google.maps.latlng(lat,lng),        map: map     });      var infowindow = new google.maps.infowindow({        content: contentstring     });      google.maps.event.addlistener(marker, 'click', function() {        infowindow.open(map, marker);     });      bounds.extend(marker.position); }
