Hi folks
Firstly I am a bit of a newbie...I am working through
http://code.google.com/apis/maps/articles/phpsqlajax_v3.html this tutorial
and it is going well so far.
Now I am trying to get a bit creative with it but I am having difficulty
with a click event.
Basically, all I want to do now is be able to zoom and center on a marker
when clicked. I cannot for the life of me figure out how to do this. Any
help will be appreciated!
Here's the code thus far:
[code]
//<![CDATA[
var customIcons = {
harbour: {
icon: 'http://labs.google.com/ridefinder/images/mm_20_blue.png',
shadow: 'http://labs.google.com/ridefinder/images/mm_20_shadow.png'
},
lake: {
icon: 'http://labs.google.com/ridefinder/images/mm_20_red.png',
shadow: 'http://labs.google.com/ridefinder/images/mm_20_shadow.png'
}
};
function load() {
var map = new google.maps.Map(document.getElementById("map"), {
center: new google.maps.LatLng(-36.818, 174.913),
zoom: 6,
mapTypeId: 'hybrid'
});
var infoWindow = new google.maps.InfoWindow;
// Change this depending on the name of your PHP file
downloadUrl("phpsqlajax_genxml.php", function(data) {
var xml = data.responseXML;
var markers = xml.documentElement.getElementsByTagName("marker");
for (var i = 0; i < markers.length; i++) {
var name = markers[i].getAttribute("name");
//var address = markers[i].getAttribute("address");
var type = markers[i].getAttribute("type");
var point = new google.maps.LatLng(
parseFloat(markers[i].getAttribute("lat")),
parseFloat(markers[i].getAttribute("lng")));
var markid = markers[i].getAttribute("id");
var imagepath = markers[i].getAttribute("image");
if(imagepath == "Please add an image") {
var html = "<b>" + name + "</b><br/>ID: " + markid + "<br/>" +
imagepath;
} else {
var html = "<b>" + name + "</b><br/>ID: " + markid + "<br/><img src='"
+ imagepath + "' alt='' width='200px' />";
}
var icon = customIcons[type] || {};
var marker = new google.maps.Marker({
map: map,
position: point,
icon: icon.icon,
shadow: icon.shadow
});
bindInfoWindow(marker, map, infoWindow, html);
}
});
}
function bindInfoWindow(marker, map, infoWindow, html) {
google.maps.event.addListener(marker, 'click', function() {
infoWindow.setContent(html);
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>
</head>
<body onLoad="load()">
<div id="map" style="width: 100%; height: 80%"></div>
</body>
</html>
