Wordpress ACF和谷歌地图按类别过滤...和缩放

我在wordpress网站上使用谷歌地图和acf构建地图。我的目标是按类别创建可过滤的地图:帖子是城市,它们分为类别,类别是国家。我为每个类别创建了一个单选按钮列表,当我点击它时,我一次只显示一个类别。

问题是当我点击一个单选按钮并显示一个国家的标记时,我想放大该国家。地图保持相同的缩放级别。我知道网上有很多类似的例子,但是当点击单选按钮时,它们都没有让地图放大。 是否有人能以这种方式告诉我它是否可能? 我也尝试使用集群,在这种情况下缩放工作,但挑战是让它使用过滤器(单选按钮或复选框或选择..) 感谢任何可以帮助我的人! :)

这是google.js代码

(function($) {

// New Map   
// This function will render a Google Map onto the selected jQuery element

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

        zoom        : 4,
        center      : new google.maps.LatLng(0, 0),
        mapTypeId   : google.maps.MapTypeId.ROADMAP,

    };
    // create map               
    var map = new google.maps.Map( $el[0], args);

    // add a markers reference
    map.markers = [];
    // add markers

    // Filter Markers
    $('.virtual-map-filter').on('change', 'input[type="radio"]', function() {
        filter = $(this);
        filterValue = filter.val();
        if(filter.is(':checked')) {

        }
    });
    $markers.each(function(){

    }); 

    // center map
    center_map( map );
    // return
    return map;

// Add Marker

    });
    // add to array
    map.markers.push( marker );
    //first hide all the markers
    marker.setVisible(false);

    // 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;

    });
    }
}
// Center 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 );
        map.fitBounds(bounds);

    });
    // only 1 marker?
    if( map.markers.length == 1 ) {
        // set center of map

    }


  }

    });

})(jQuery);

这里是html / php部分

<div class="map-container">
        <?php
        $terms = get_field('category_select');
        if( $terms ): ?>
        <?php foreach( $terms as $term ): 
        $args = array(
            'post_type' => 'post', 
            'category__in' => $term
            );
        $the_query = new WP_Query($args); 
;?><div class="acf-map"><?php
        while ( $the_query->have_posts() ) : $the_query->the_post();
        $location = get_field('google_maps');?>

        <?php
        if( !empty($location) ) { 
            ?>
            <div class="marker" data-category="<?php echo $term->slug ;?>" data-lat="<?php echo $location['lat']; ?>" data-lng="<?php echo $location['lng']; ?>">
                <?php the_post_thumbnail('thumbnail'); ?>
                <h4><a href="<?php the_permalink(); ?>" rel="bookmark"> <?php the_title(); ?></a></h4>
                <p class="address"><?php echo $location['address']; ?></p>
            </div>
            <?php
        }
        endwhile; 
        wp_reset_postdata();

谢谢! 最后我设法做到了,但代码可能不是最好的..我保持php文件相同,但改变了像这样的js文件: - 在new_map函数中,我添加了一个新的&#39; google.maps.LatLngBounds()&#39;如果标记是可见的,我用以下内容扩展边界:&#39; bounds.extend($ markers.getPosition())&#39;。首先,我的所有标记都被隐藏,其中包含标记.setVisible(false)&#39;在add_marker函数中。当我点击一个单选按钮时,地图缩放到所选国家!! 问题是,我不知道这是否是最佳方式......如果您有任何建议!感谢
