У меня есть forloop, у которого есть вызов функции внутри него. В этой функции я помещаю значения в массив, называемый маркерами.
Есть ли способ получить доступ к значениям массива маркеров вне forloop?
Вот код:
<script type="text/javascript">
// arrays to hold copies of the markers and html used by the side_bar
// because the function closure trick doesnt work there
var map = null;
geocoder = new google.maps.Geocoder();
var side_bar_html = "";
var icon = '';
var markers = [];
function codeAddress(this_address,index,callback) {
geocoder.geocode( { 'address': this_address}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
callback.call(window,index,results[0].geometry.location)
} else {
alert("Geocode was not successful for the following reason: " + status);
}
});
}
function initialize() {
// create the map
var myOptions = {
zoom: 3,
center: new google.maps.LatLng(46.90, -121.00),
mapTypeControl: true,
mapTypeControlOptions: {style: google.maps.MapTypeControlStyle.DROPDOWN_MENU},
navigationControl: true,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
google.maps.event.addListener(map, 'click', function() {
infowindow.close();
});
for (var i = 0; i < businesses.length; i++) {
codeAddress(businesses[i].address,i,function(i,point){
var description = businesses[i].description;
if(businesses[i].business_type == "Wine"){
//http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=A|00CC99|000000
icon = 'http://google-maps-icons.googlecode.com/files/wineyard.png';
}else if(businesses[i].business_type == "Golf"){
icon = 'http://google-maps-icons.googlecode.com/files/golf.png';
}else{
icon = 'http://google-maps-icons.googlecode.com/files/festival.png';
}
var marker = createMarker(point,businesses[i].name,description,icon);
// put the assembled side_bar_html contents into the side_bar div
document.getElementById("side_bar").innerHTML = side_bar_html;
});//End codeAddress-function
}//End for-loop
console.log(markers);
var markerCluster = new MarkerClusterer(map, markers);
}
// A function to create the marker and set up the event window function
function createMarker(latlng, name, html,icon) {
var contentString = html;
var marker = new google.maps.Marker({
position: latlng,
map: map,
icon: icon,
zIndex: Math.round(latlng.lat()*-100000)<<5
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent(contentString);
infowindow.open(map,marker);
});
// save the info we need to use later for the side_bar
markers.push(marker);
// add a line to the side_bar html
side_bar_html += '<a href="javascript:myclick(' + (markers.length-1) + ')">' + name + '<\/a><br />'+html+'<br />';
}
var infowindow = new google.maps.InfoWindow({
size: new google.maps.Size(150,50)
});
// This function picks up the click and opens the corresponding info window
function myclick(i) {
google.maps.event.trigger(markers[i], "click");
}
</script>
Как видите, в последней строке написано "var markerCluster = new MarkerClusterer (map, markers);" Здесь я хочу получить доступ к информации.
Спасибо!
