ACF 谷歌地图 - 标记聚类

Question

我一直在扯我的头发（不是我有任何......）试图让我的头绕过这个，我尽可能接近 ACF 谷歌地图示例，我有每个位置（发布）在地图上绘制很好，但不能让集群正常工作，我真的很感激在我正在尝试做的正确上下文中的一些帮助。我发现的所有解决方案似乎都无法解决问题。

InvalidValueError: setMap: not an instance of Map; and not an instance of StreetViewPanorama,

Uncaught TypeError: this.map_.getZoom is not a function

我的 JS 如下（对帖子格式感到抱歉！！！）：

任何帮助都会很棒...

Answer 1

我在render_map()下添加如下。如上所述，您还需要将 MarkerClusterPlus 库与 Maps JavaScript API 一起添加到您的脚本中

// add marker cluster
var markerCluster = new MarkerClusterer(map, map.markers, {
    imagePath: 'https://developers.google.com/maps/documentation/javascript/examples/markerclusterer/m'
});

Answer 2

我也有同样的问题。我用包含修复它

<script src="https://developers.google.com/maps/documentation/javascript/examples/markerclusterer/markerclusterer.js"></script>

在页脚中，这是我的代码：

(function($) {

/*
*  new_map
*
*  This function will render a Google Map onto the selected jQuery element
*
*  @type    function
*  @date    8/11/2013

*
*  @param   $el (jQuery element)
*  @return  n/a
*/

function new_map( $el ) {

// var
var $markers = $el.find('.marker');


// vars
var args = {
    zoom        : 16,
    center      : new google.maps.LatLng(46.8, 1.9),
    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 );

});


// center map
center_map( map );

// add marker cluster
markerCluster( map.markers, map )

// return
return map;

}

/*

*  @return  n/a
*/

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() {

        if (typeof( window.infoopened ) != 'undefined') infoopened.close();
        infowindow.open(map,marker);
        infoopened = infowindow;

    });
}


}

function markerCluster( markers, map ) {
    var markerCluster = new MarkerClusterer(map, markers, {imagePath: 'https://developers.google.com/maps/documentation/javascript/examples/markerclusterer/m'});
    //console.log( markers );

*/

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 );

}


/*

// global var
