我一直在試圖遵循Google的教程來實現帶有MySQL和PHP的Google Maps。這裏是我的代碼:使用Google地圖時在控制檯中的錯誤:未捕獲的ReferenceError:圖標未定義
<div class="container">
<div id="map">
</div>
</div>
<script>
function initMap() {
var map = new google.maps.Map(document.getElementById('map'), {
center: new google.maps.LatLng(XX.XXX, XX.XXX),
zoom: 12
});
var infoWindow = new google.maps.InfoWindow;
// Change this depending on the name of your PHP or XML file
downloadUrl('http://xxxxxx.com/xxxxxxxx.php/', function(data) {
var xml = data.responseXML;
var markers = xml.documentElement.getElementsByTagName('marker');
Array.prototype.forEach.call(markers, function(markerElem) {
var id = markerElem.getAttribute('id');
var point = new google.maps.LatLng(
parseFloat(markerElem.getAttribute('lat')),
parseFloat(markerElem.getAttribute('lng')));
var infowincontent = document.createElement('div');
var strong = document.createElement('strong');
strong.textContent = id
infowincontent.appendChild(strong);
infowincontent.appendChild(document.createElement('br'));
var marker = new google.maps.Marker({
map: map,
position: point,
label: icon.label
});
marker.addListener('click', function() {
infoWindow.setContent(infowincontent);
infoWindow.open(map, marker);
});
});
});
}
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);
}
function doNothing() {}
</script>
<script async defer
src="https://maps.googleapis.com/maps/api/js?key=XXXXXXXXXXXXXXXX&callback=initMap">
</script>
我已經成功地跟着教程完成創建創建XML數據的PHP腳本的點,我打電話,在將downloadURL功能數據。但是,本教程基於使用靜態XML文件。我認爲我需要改變一些東西,讓標記出現在地圖上。當我打開控制檯我的網頁上,即時得到以下錯誤:
未捕獲的ReferenceError:57
在HTMLCollection.forEach()
:圖標沒有在profile.php定義
在profile.php:41
在XMLHttpRequest.request.onreadystatechange(profile.php:77)
關於如何解決噸任何想法這些錯誤?我一直堅持這幾個小時。提前致謝!
的'icon'變量沒有定義(而它在您開始使用谷歌的例子) – geocodezip
