OK, I think I've mananged two of your three steps:
Step 1: I have put 'var bounds' at the start of the initialize
function.
Step 2: I have put the 'bounds.extend(points);' in the 'for (var i =
0; i < markers.length; i++)' loop.
But I can't figure out where to put 'map.fitBounds(bounds);'
The whole function initialize() looks like this:
function initialize()
{
var bounds = new google.maps.LatLngBounds(); //Makes an empty bounds
object
var latlng = new google.maps.LatLng(48.130000, 25.570000);
var myOptions = {
zoom: 4,
center: latlng,
mapTypeId: google.maps.MapTypeId.HYBRID
};
var map = new google.maps.Map(document.getElementById("map_canvas"),
myOptions);
var infoWindow = new google.maps.InfoWindow;
// Change this depending on the name of your PHP file
downloadUrl("min_genxml3.php?art=<?php echo $afart.'&dist='.
$min_dist.'&tid='.$max_time;?>", function(data)
{
var xml = parseXml(data);
var markers = xml.documentElement.getElementsByTagName("marker");
for (var i = 0; i < markers.length; i++)
{
var icon = 'http://labs.google.com/ridefinder/images/
mm_20_red.png';
var point = new
google.maps.LatLng(parseFloat(markers[i].getAttribute("lat")),
parseFloat(markers[i].getAttribute("lng")));
var mdat = 'Markt: '+markers[i].getAttribute("mdat");
var fdat = 'Funnen: '+markers[i].getAttribute("fdat");
var dist = 'Distans: '+markers[i].getAttribute("dist")+' km.';
var riktn = 'Riktning: '+markers[i].getAttribute("riktn")+'
grader.';
var dgr = 'Tid: '+markers[i].getAttribute("dgr")+' dagar.';
var html = 'Märkt: '+markers[i].getAttribute("mdat")+'<br>Funnen:
'+markers[i].getAttribute("fdat")+'<br>Förfluten tid:
'+markers[i].getAttribute("dgr")+' dagar.';
var marker = new google.maps.Marker
(
{
position: point,
map: map,
title: dist+' '+riktn,
icon: icon
}
);
bindInfoWindow(marker, map, infoWindow, html);
// Feed your bounds object with your points
bounds.extend(points);
}
}
);
}
Could you please tell me where to put 'map.fitBounds(bounds);' among
all these curly and non-curly brackets?
Thank you
