所以我的网络服务器上有一个Google-maps API。我可以使用地理位置lat和lng显示标记。当您单击标记时,您可以看到有关它的一些信息。我提供信息" Vorname,Nachname,PLZ,Adresse"但它唯一的表现" Vorname" ?
如何在标记中显示所有变量?
<body>
<div id="map"></div>
<script>
function initMap()
{
var map = new google.maps.Map(document.getElementById('map'),
{
center: new google.maps.LatLng(51.5167, 9.9167),
zoom: 6
});
var infoWindow = new google.maps.InfoWindow;
downloadUrl('geomap.php', function(data)
{
var xml = data.responseXML;
var markers = xml.documentElement.getElementsByTagName('marker');
Array.prototype.forEach.call(markers, function(markerElem)
{
var Nachname = markerElem.getAttribute('Nachname');
var Vorname = markerElem.getAttribute('Vorname');
var Adresse = markerElem.getAttribute('Adresse');
var plz = markerElem.getAttribute('plz');
var point = new google.maps.LatLng(
parseFloat(markerElem.getAttribute('geolat')),
parseFloat(markerElem.getAttribute('geolong')));
var infowincontent = document.createElement('div');
var strong = document.createElement('strong');
strong.textContent = Nachname;
//strong.textContent = Vorname;
infowincontent.appendChild(strong);
infowincontent.appendChild(document.createElement('br'));
var text = document.createElement('text');
infowincontent.appendChild(text);
var marker = new google.maps.Marker(
{
map: map,
position: point
});
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=apikey&callback=initMap">
</script>
</body>
答案 0 :(得分:0)
因为根据您的代码,这是您添加到节点的文字内容中的唯一内容:strong.textContent = Nachname;
。
如果您想要显示其他变量,则应该类似于strong.textContent = Nachname + ', ' + Vorname + ', ' + plz + ', ' + Adresse;
。
