KML-file loaded but background map not visible
This is what I used to display a KML-file in Google Maps:
HTML
<div id="map_canvas" style="width: 600px; height: 400px"></div>
Javascript
function map_initialize() {
var myLatlng = new google.maps.LatLng(52.200874,6.009521);
var myOptions = {
zoom: 7,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.HYBRID
};
var map = new google.maps.Map(
document.getElementById("map_canvas"),
myOptions);
var nyLayer = new google.maps.KmlLayer(
'http://maps.google.com/maps/ms?ms开发者_StackOverflowa=0&msid=114680467578999980893.00049426282c85822d40e&output=kml');
nyLayer.setMap(map);
}
jQuery(function(){map_initialize()});
Here you can see the result: http://www.taizefriesland.nl/?page_id=7
The KML-file is loaded but the background map is not visible. How can I show the hibryd background map?
I've seen this problem before, when I first started using the Google Maps API V3. If you used any document type other than HTML 5 (using just the doctype element as they show in their "Hello World" map) this exact behavior would be exhibited. Google has improved the API since then, and you can actually use a doctype such as XHTML 1.0 Transitional, HTML 4.0.1 Strict, and suchlike. I see that you're using XHTML 1.0 Transitional, so that's what I used in this cut down example:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<p>Uit het feit dat Taizé wekelijks duizenden jongeren ontvangt, blijkt dat het jongeren aanspreekt om bij een gebed in de sfeer van Taizé aanwezig te zijn.<br>

Het Taizégebed is oecumenisch: het wordt meestal voorbereid door jonge mensen die afkomstig zijn uit verschillende kerken.</p>

To help see if it made a difference, I've loaded all the JS libs and CSS that your page is using. As a first crack, try doing what I did and adding an explicit style definition (but leave your inline one) that specifies the dimensions of #map_canvas as 600px wide and 400px high. I know there are limitations when you're using WordPress, so that a lot of the HTML above is actually generated by it, not you manually editing. The only thing I can guess is that there's something modifying the z-index of the elemnts in your DIV. Taking the above HTML and putting it on a web server works 100%.
