14. Problema 2 Se eu pudesse saber onde estão estas malditas tartarugas...
15. Localização navigator.geolocation.getCurrentPosition()
16. Onde estou? Opa! Você está por aqui.
17. Onde estou? Opa! Você está por aqui. WTF?
18. Persistindo... CREATE TABLE turtles( localization varchar(255), lat varchar(255), long varchar(255) );
19. Persistindo... INSERT INTO `turtles` VALUES( `Yoshi\`s Island`, 199089, -7040 );
20. Persistindo... BASE DE DADOS COM INFORMAÇÕES DE LAT E LONG
22. XML? By using an XML file as an intermediary between your database and your Google Map, it makes for a faster initial page load, a more flexible map application, and easier debugging.
23. XML? <?php $mysqlConnection = new \PDO('...'); $statement = $mysqlConnection->query( ”SELECT * FROM turtles” ); $enemyLocation = $statement->fetchAll(PDO::FETCH_OBJ); foreach ($enemyLocation as $place) { / / ... }
24. XML? <markers> <marker name="Yoshi's Island" lat="199089" lng="-7040"/> <marker name="Star Road" lat="47 .608940" lng="-122.340141"/> <marker name="Forest of Illusion" lat="90809" lng="-37 .2465"/> <marker name="Valley of Bowser" lat="91.2763" lng="-14.1998"/> </markers>
25. Criando o Mapa
26. Criando o Mapa... Carregando XML... API v2 GDownloadUrl API v3 ---
27. Criando o Mapa... function downloadUrl(url, callback) { var request = window.ActiveXObject ? new ActiveXObject('Microsoft.XMLHTTP') : new XMLHttpRequest; request.onreadystatechange = function() { if (request.readyState == 4) { request.onreadystatechange = doNothing; callback(request, request.status); } }; request.open('GET', url, true); request.send(null); }
28. Criando o Mapa... “XMLHttpRequest is asynchronous”
29. Criando o Mapa... downloadUrl("xmlGenerator.php", function(data) { var xml = data.responseXML; var markers = xml.documentElement.getElementsByTagName("marker"); for (var i = 0; i < markers.length; i++) { var name = markers[i].getAttribute("name"); var point = new google.maps.LatLng( parseFloat(markers[i].getAttribute("lat")), parseFloat(markers[i].getAttribute("lng")) ); var html = "<b>" + name + "</b> <br/>"; var marker = new google.maps.Marker({ map: map, position: point, }); bindInfoWindow(marker, map, infoWindow, html); } });
30. Markers :/
31. Marker Personalizado... var customIcons = { enemy: { icon: 'pictures/pin.png' } }
32. Markers *_*
33. Markers e Infos... function bindInfoWindow(marker, map, infoWindow, html) { google.maps.event.addListener(marker, 'click', function() { infoWindow.setContent(html); infoWindow.open(map, marker); }); }
34. Infos Yoshi’s Island
