我試圖實施https://github.com/jawj/OverlappingMarkerSpiderfier來處理可能發生在同一地點的多個地圖標記。我使用下面的JavaScript從類.marker的div中獲取地圖數據並創建地圖。它運作良好，效果很好。實施Google地圖Spiderfier
function initialize() {
function render_map($el) {
// var
var $markers = $el.find('.marker');
// vars
var args = {
zoom : 8,
center : new google.maps.LatLng(42.7086815, -84.559032),
scrollwheel : false,
mapTypeId : google.maps.MapTypeId.ROADMAP
};
// create map
var map = new google.maps.Map($el[0], args);
// add a markers reference
map.markers = [];
// add markers
$markers.each(function(){
add_marker($(this), map);
});
var padder = document.createElement('div');
padder.style.height = '100px';
padder.style.width = '100%';
map.controls[google.maps.ControlPosition.TOP_CENTER].push(padder);
// center map
center_map(map);
}
function add_marker($marker, map) {
// var
var latlng = new google.maps.LatLng($marker.attr('data-lat'), $marker.attr('data-lng'));
// create marker
var marker = new google.maps.Marker({
position : latlng,
map : map
});
// add to array
map.markers.push(marker);
// if marker contains HTML, add it to an infoWindow
if($marker.html())
{
// create info window
var infowindow = new google.maps.InfoWindow({
content : $marker.html()
});
// show info window when marker is clicked
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map, marker);
map.setCenter(marker.getPosition());
});
}
}
function center_map(map) {
// vars
var bounds = new google.maps.LatLngBounds();
// loop through all markers and create bounds
$.each(map.markers, function(i, marker){
var latlng = new google.maps.LatLng(marker.position.lat(), marker.position.lng());
bounds.extend(latlng);
});
// only 1 marker?
if(map.markers.length == 1)
{
// set center of map
map.setCenter(bounds.getCenter());
}
else if(map.markers.length == 0)
{
// set center of map
map.setCenter(42.7086815, -84.559032);
}
else
{
// fit to bounds
map.fitBounds(bounds);
}
google.maps.event.addListenerOnce(map, 'bounds_changed', function(event) {
if (this.getZoom() > 8) {
this.setZoom(8);
}
});
}
$(document).ready(function(){
$('#acf-map').each(function(){
render_map($(this));
});
});
}
但是，當我嘗試整合我與Spiderfier js所具有的功能時，地圖標記未顯示出來。這是我合併js的抱歉嘗試。對我如何使用Spiderfier有任何想法，但仍然從.marker div中獲取內容？
function initialize() {
function render_map($el) {
// var
var $markers = $el.find('.marker');
// vars
var args = {
zoom : 8,
center : new google.maps.LatLng(42.7086815, -84.559032),
scrollwheel : false,
mapTypeId : google.maps.MapTypeId.ROADMAP
};
// create map
var map = new google.maps.Map($el[0], args);
var oms = new OverlappingMarkerSpiderfier(map);
var iw = new google.maps.InfoWindow();
oms.addListener('click', function(marker, event) {
iw.setContent(marker.desc);
iw.open(map, marker);
});
oms.addListener('spiderfy', function(markers) {
iw.close();
});
// var
var latlng = new google.maps.LatLng($marker.attr('data-lat'), $marker.attr('data-lng'));
// create marker
var marker = new google.maps.Marker({
position : latlng,
map : map
});
marker.desc = $marker.html();
oms.addMarker(marker);
var padder = document.createElement('div');
padder.style.height = '100px';
padder.style.width = '100%';
map.controls[google.maps.ControlPosition.TOP_CENTER].push(padder);
// center map
center_map(map);
}
function center_map(map) {
// vars
var bounds = new google.maps.LatLngBounds();
// loop through all markers and create bounds
$.each(map.markers, function(i, marker){
var latlng = new google.maps.LatLng(marker.position.lat(), marker.position.lng());
bounds.extend(latlng);
});
// only 1 marker?
if(map.markers.length == 1)
{
// set center of map
map.setCenter(bounds.getCenter());
}
else if(map.markers.length == 0)
{
// set center of map
map.setCenter(42.7086815, -84.559032);
}
else
{
// fit to bounds
map.fitBounds(bounds);
}
google.maps.event.addListenerOnce(map, 'bounds_changed', function(event) {
if (this.getZoom() > 8) {
this.setZoom(8);
}
});
}
$(document).ready(function(){
$('#acf-map').each(function(){
render_map($(this));
});
});
}
