Google地图切换 [英] Google maps in toggle
问题描述
我在摆放goole地图时遇到问题。
我使用简单的切换打开地图,但我只看到地图的一部分。
这是结果的印记:

elem.toggle('fast');

$(document).ready(function(){
$('。acf ()函数(){
render_map($(this));
});
});
})(jQuery);
这是content.php中的代码
<?php $ location = get_field('luogo'); if($ location ['address']){?>
< a href =#class =togglelink-map> accedi< / a>
< div class =acf-map>
< div class =markerdata-lat =<?php echo $ location ['lat'];?> data-lng =<?php echo $ location ['lng'];?> itemprop = 地图 >< / DIV>
< / div>
<?php}?>
基本问题是map-div )在创建地图时没有大小。
最简单的方法是在切换地图时触发窗口的调整大小事件(以看看最后一行):
$(document).ready(function(){
$('。 ('click',function(e){
e.preventDefault();
('a.togglelink-map')。 (elem).hide('fast');
$ b $('。acf-map')。 b elem.toggle('fast',function(){google.maps.event.trigger(window,'resize')});
});
});
问题:地图不会在所需位置居中,并且没有处理
另一种方法:
触发map-div的自定义事件:
$(document).ready(function(){
$('。acf-map')。 hide();
$('a.togglelink-map')。on('click',function(e){
e.preventDefault();
var elem = $(this ).next('.acf-map')
$('。acf-map')。not(elem).hide('fast');
elem.toggle('快速',function(){google.maps.event.trigger(this,'toggle');});
});
});
在render_map中为此自定义事件定义一个处理程序:
map =(function(o,a){
var m = new google.maps.Map(o,a);
google.maps。 event.addListener(o,'toggle',function(){
var c = m.getCenter();
google.maps.event.trigger(m,'resize');
if(!m.get('centered')){
m.setCenter(c);
m.set('centered',1);
}
}) ;
返回m;
})($ el [0],args);

I have problems with lay out of the goole maps. I am using simple toggle to open the map, but i see only a part of the map.
Then i use acf (advanced custom field) for wordpress to show the map. But i have seen that toggle is in conflict with google api.
This is a stamp of the result:

Here is the code:
/*toggle*/
$(document).ready(function () {
$('.acf-map').hide();
$('a.togglelink-map').on('click', function (e) {
e.preventDefault();
var elem = $(this).next('.acf-map')
$('.acf-map').not(elem).hide('fast');
elem.toggle('fast');
});
});
/*acf render map*/
(function ($) {
/*

*

*
* @type function

*/
var map;
function render_map($el) {
// var
var $markers = $el.find('.marker');
// vars
var args = {
zoom: 16,
center: new google.maps.LatLng(0, 0),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
// create map
map = new google.maps.Map($el[0], args);
// add a markers reference
map.markers = [];
// add markers
$markers.each(function () {
add_marker($(this), map);
});
// 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);
});
}
}

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());
map.setZoom(16);
} else {
// fit to bounds
map.fitBounds(bounds);
}
$(document).on('click', '.map', function () {
google.maps.event.trigger(map, 'resize');
map.setCenter(bounds.getCenter());
map.setZoom(16);
});
}
/*

*

*/
$(document).ready(function () {
$('.acf-map').each(function () {
render_map($(this));
});
});
})(jQuery);
This is the code in content.php
<?php $location = get_field('luogo'); if($location['address']) { ?>
<a href="#" class="togglelink-map">accedi</a>
<div class="acf-map">
<div class="marker" data-lat="<?php echo $location['lat']; ?>" data-lng="<?php echo $location['lng']; ?>" itemprop="map"></div>
</div>
<?php } ?>
The basic issue is that the map-div(s) don't have a size when you create the map.
The easiest approach would be to trigger the resize-event of the window when you toggle a map(take a look at the last line):
$(document).ready(function () {
$('.acf-map').hide();
$('a.togglelink-map').on('click', function (e) {
e.preventDefault();
var elem = $(this).next('.acf-map')
$('.acf-map').not(elem).hide('fast');
elem.toggle('fast',function(){google.maps.event.trigger(window,'resize')});
});
});
The problem: the map will not be centered at the desired position, and there is no handle to the maps-instance to apply a centering.
Another approach:
Trigger a custom event for the map-div:
$(document).ready(function () {
$('.acf-map').hide();
$('a.togglelink-map').on('click', function (e) {
e.preventDefault();
var elem = $(this).next('.acf-map')
$('.acf-map').not(elem).hide('fast');
elem.toggle('fast',function(){google.maps.event.trigger(this,'toggle');});
});
});
In render_map define a handler for this custom event:
map = (function (o, a) {
var m = new google.maps.Map(o, a);
google.maps.event.addListener(o, 'toggle', function () {
var c = m.getCenter();
google.maps.event.trigger(m, 'resize');
if(!m.get('centered')){
m.setCenter(c);
m.set('centered',1);
}
});
return m;
})($el[0], args);
