我最近切換到了Google Maps API V3。我正在研究一個(gè)從數(shù)組繪制標(biāo)記的簡(jiǎn)單示例，但是我不知道如何相對(duì)于標(biāo)記自動(dòng)居中和縮放。我搜尋了包括谷歌自己的文檔在內(nèi)的最高和最低值，但沒(méi)有找到明確的答案。我知道我可以簡(jiǎn)單地取坐標(biāo)的平均值，但是如何設(shè)置縮放比例呢？function initialize() { var myOptions = { zoom: 10, center: new google.maps.LatLng(-33.9, 151.2), mapTypeId: google.maps.MapTypeId.ROADMAP } var map = new google.maps.Map(document.getElementById("map_canvas"),myOptions); setMarkers(map, beaches);}var beaches = [ ['Bondi Beach', -33.890542, 151.274856, 4], ['Coogee Beach', -33.423036, 151.259052, 5], ['Cronulla Beach', -34.028249, 121.157507, 3], ['Manly Beach', -33.80010128657071, 151.28747820854187, 2], ['Maroubra Beach', -33.450198, 151.259302, 1]];function setMarkers(map, locations) { var image = new google.maps.MarkerImage('images/beachflag.png', new google.maps.Size(20, 32), new google.maps.Point(0,0), new google.maps.Point(0, 32)); var shadow = new google.maps.MarkerImage('images/beachflag_shadow.png', new google.maps.Size(37, 32), new google.maps.Point(0,0), new google.maps.Point(0, 32)); var lat = map.getCenter().lat(); var lng = map.getCenter().lng(); var shape = { coord: [1, 1, 1, 20, 18, 20, 18 , 1], type: 'poly' }; for (var i = 0; i < locations.length; i++) { var beach = locations[i]; var myLatLng = new google.maps.LatLng(beach[1], beach[2]); var marker = new google.maps.Marker({ position: myLatLng, map: map, shadow: shadow, icon: image, shape: shape, title: beach[0], zIndex: beach[3] }); }}
Google Map API v3-設(shè)置范圍和中心
