Ok, that's it !
Now, the first 'GDownloadUrl' launches the second 'GDownloadUrl'. And
it works each time.
I keep my $(document).ready(function (){}) moreover.
Thanks for your help.
Here is the new code.
$(document).ready(function () {
if (GBrowserIsCompatible()) {
var markerGroups = [];
var pictosFleuveRhone = [];
var center = new GLatLng(44.824708282300236, 5.25146484375);
var zoom_level = 8;
function createMarker(point, name, label, type, detail) {
var marker = new LabeledMarker(point, {icon:
pictosFleuveRhone[type]});
markerGroups[type].push(marker);
var html = "<strong>" + name + "</strong> <br/>"+detail;
GEvent.addListener(marker, 'click', function() {
marker.openInfoWindowHtml(html);
});
return marker;
}
function toggleGroup() {
var btn=$(this);
var type=btn.attr('id');
var css_class=btn.attr('class');
if (css_class == 'actif') {
btn.removeAttr('class');
} else {
btn.addClass('actif');
}
for (var i = 0; i < markerGroups[type].length; i++) {
var marker = markerGroups[type][i];
if (marker.isHidden()) {
marker.show();
} else {
marker.hide();
}
}
}
var map = new GMap2(document.getElementById("map_canvas"));
map.addMapType(G_PHYSICAL_MAP);
map.setCenter(center, zoom_level, G_PHYSICAL_MAP);
var customUI = map.getDefaultUI();
customUI.zoom.scrollwheel = true;
map.setUI(customUI);
// Récupération des catégories pour constituer les groupes de
points
// On récupère également le picto
GDownloadUrl("/gmapdata/list/245/listCategories/categories",
function(data){
var xml = GXml.parse(data);
var categories = xml.documentElement.getElementsByTagName
("categorie");
for (var i = 0; i < categories.length; i++) {
// Constitution du groupe
var cat_id=categories[i].getAttribute("id");
markerGroups[cat_id] = [];
$("a#"+cat_id).click(toggleGroup);
// Constitution du picto
pictosFleuveRhone[cat_id] = new GIcon();
pictosFleuveRhone[cat_id].image = categories
[i].getAttribute("picto");
pictosFleuveRhone[cat_id].iconSize = new GSize(20,
20);
pictosFleuveRhone[cat_id].iconAnchor = new GPoint(16,
16);
pictosFleuveRhone[cat_id].infoWindowAnchor = new GPoint
(5, 1);
pictosFleuveRhone[cat_id].shadow = '';
pictosFleuveRhone[cat_id].shadowSize = new GSize(22,
20);
//if(i==22){alert('fin traitement categories');}
}
downloadThen();
});
function downloadThen() {
// Récupération des lieux
GDownloadUrl("/gmapdata/list/197/listLocation/
mapitem", function(data){
var xml = GXml.parse(data);
var markers =
xml.documentElement.getElementsByTagName("marker");
for (var i = 0; i < markers.length; i++) {
var name = markers[i].getAttribute("name");
var detail = markers[i].getAttribute
("detail");
var label = i;
var type = markers[i].getAttribute("type_id");
var point = new GLatLng(parseFloat(markers
[i].getAttribute("lat")), parseFloat(markers[i].getAttribute("lng")));
var marker = createMarker(point, name, label,
type, detail);
map.addOverlay(marker);
}
});
}
}
});
