I have a requirement to display multiple Google markers on a map based on addresses stored in a database. I have already successfully loaded an XML file to retrieve latitude and longitude coordinates, but now I need assistance on how to create multiple markers based on address information using PHP or JSON. The code snippet below shows how I loaded the XML file:
<div class="map">
<div id="map"></div>
<script>
var customLabel = {
restaurant: {
label: 'R'
},
bar: {
label: 'B'
}
};
// var locs = [ ["-33.863276, 151.207977"],customLabel
function initMap() {
var map = new google.maps.Map(document.getElementById('map'), {
center: new google.maps.LatLng(12.92279500, 77.61440500),
zoom: 12
});
var infoWindow = new google.maps.InfoWindow;
downloadUrl('http://www.rentozy.in/rentozy.xml', function(data) {
var xml = data.responseXML;
var markers = xml.documentElement.getElementsByTagName('marker');
Array.prototype.forEach.call(markers, function(markerElem) {
var id = markerElem.getAttribute('pg_id');
var name = markerElem.getAttribute('name');
var address = markerElem.getAttribute('pg_address');
var type = markerElem.getAttribute('pg_type');
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 = name
infowincontent.appendChild(strong);
infowincontent.appendChild(document.createElement('br'));
var text = document.createElement('text');
text.textContent = address
infowincontent.appendChild(text);
var icon = customLabel[type] || {};
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>
