在谷歌地圖上添加標記
[英]add marker on google maps
問題描述
我只想在谷歌地圖 API 中添加標記
我正在嘗試創建自定義標記和半徑圓。 我使用過谷歌地圖地理編碼服務。 基本上我想在選定的城市中顯示某些半徑的推文，並將個人資料圖片作為標記和信息框。

地理編碼器是異步的，您需要在回調函數中使用返回的數據何時/何地可用。 將標記/圓圈定義移動到地理編碼器的回調函數中：
代碼片段：
function initMap() { var place = { lat: 13.7565, lng: 100.5018 }; var map = new google.maps.Map(document.getElementById('map'), { zoom: 8, center: place }); var geocoder = new google.maps.Geocoder(); document.getElementById('submit').addEventListener('click', function() { geocodeAddress(geocoder, map); }); geocodeAddress(geocoder, map); } function geocodeAddress(geocoder, resultsMap) { var address = document.getElementById('address').value; geocoder.geocode({ 'address': address }, function(results, status) { if (status === google.maps.GeocoderStatus.OK) { resultsMap.setCenter(results[0].geometry.location); var marker = new google.maps.Marker({ map: resultsMap, position: results[0].geometry.location }); var circle = new google.maps.Circle({ map: marker.getMap(), radius: 16093, // 10 miles in metres fillColor: '#AA0000' }); circle.bindTo('center', marker, 'position'); } else { alert('Geocode was not successful for the following reason: ' + status); } }); } google.maps.event.addDomListener(window, "load", initMap);
html, body { height: 100%; margin: 0; padding: 0; } #map { height: 100%; } #floating-panel { position: absolute; top: 10px; left: 25%; z-index: 5; background-color: #fff; padding: 5px; border: 1px solid #999; text-align: center; font-family: 'Roboto', 'sans-serif'; line-height: 30px; padding-left: 10px; }
<script src="https://maps.googleapis.com/maps/api/js"></script> <div id="floating-panel"> <input id="address" type="textbox" placeholder="Bangkok" value="Bankok"> <input id="submit" type="button" value="Search"> </div> <div id="map"></div>

//objmap is the map object
// custom_data is the array of geo_location
// toolTip is the marker title
function setMarkers(objmap,custom_data,toolTip) {
var image = {
url: '../img/icon.png'
};
if(custom_data!=null) {
for (var i = 0; i < custom_data.length; i++) {
var beach = custom_data[i];
var myLatLng = new google.maps.LatLng(parseFloat(beach.lt), parseFloat(beach.lg));
var marker = new google.maps.Marker({
id: beach.vid,
position: myLatLng,
map: objmap,
icon: image,
title: toolTip,
zIndex: 1
});
google.maps.event.addListener(marker, 'click', viewMarker(marker.id));
}
}
}
