从谷歌地图之外的外部链接打开 infoWindows

Question

我目前正在使用 Google Maps API 创建属性地图。我通过自定义帖子类型控制它，该类型将标记带入地图上，点击时会打开 infoWindows。

我现在需要实现某种方式来列出地图下方的属性（最终进入滑块），以便在地图外单击属性时，地图会平移到标记并打开 infoWindow。

目前我根本无法让它工作 - 我不是一个非常强大的 javascript 编码器，所以非常感谢任何帮助。

我目前在地图下方有一个帖子类型条目的列表，但无法链接它们..

这是迄今为止地图的代码的 sn-p..

     /* MARKER 1 */

function add_marker( $marker, map ) {

    // var
    var image = 'http://www.masonyoung.co.uk/wp-content/uploads/2015/08/mason-new.png';
    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,
        icon: image
    });



    // 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, 'mouseover', function() {

            if($('.gm-style-iw').length) {
                $('.gm-style-iw').parent().hide();
            }


            infowindow.open( map, marker );


        });



            google.maps.event.addListener(marker, "mouseout", function() {
                marker.setAnimation(null);
            });




    }






}

这是迄今为止我为地图下方的属性列表提供的代码..

    <?php 
$maps = get_posts( array(
    'post_type' => 'properties',
    'posts_per_page' => -1
    ) );?>

<?php foreach($maps as $map): ?>
    <?php
     $location = get_field('location',$map->ID);
     $price = get_field('price',$map->ID);
     $squareft = get_field('sq_ft_total',$map->ID);
     $buylet = get_field('to_buy_or_to_let',$map2->ID);
     $link = the_permalink($map->ID);

?>


<div id="map_list">

       <ul id="map-locations">

            <li data-lat="<?php echo $location['lat']; ?>" data-lng="<?php echo $location['lng']; ?>">
                <h3><a href="<?php echo post_permalink( $map ); ?>"><?php echo $location['address']; ?></a></h3>
            </li>

        </ul>


     </div>


<?php endforeach; ?>

最简单的方法是将每个标记添加到标记数组中。然后为每个标记创建一个链接，其中包含对标记的标记索引的引用，这样您可以在单击外部链接时触发标记本身的单击事件。

function initialize() {

    var markers = new Array();

    var mapOptions = {
        zoom: 5,
        mapTypeId: google.maps.MapTypeId.ROADMAP,
        center: new google.maps.LatLng(1, 1)
    };

    var locations = [
        [new google.maps.LatLng(0, 0), 'Marker 1', 'Infowindow content for Marker 1'],
        [new google.maps.LatLng(0, 1), 'Marker 2', 'Infowindow content for Marker 2'],
        [new google.maps.LatLng(0, 2), 'Marker 3', 'Infowindow content for Marker 3'],
        [new google.maps.LatLng(1, 0), 'Marker 4', 'Infowindow content for Marker 4'],
        [new google.maps.LatLng(1, 1), 'Marker 5', 'Infowindow content for Marker 5'],
        [new google.maps.LatLng(1, 2), 'Marker 6', 'Infowindow content for Marker 6']
    ];

    var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);

    var infowindow = new google.maps.InfoWindow();

    for (var i = 0; i < locations.length; i++) {

        // Append a link to the markers DIV for each marker
        $('#markers').append('<a class="marker-link" data-markerid="' + i + '" href="#">' + locations[i][1] + '</a> ');

        var marker = new google.maps.Marker({
            position: locations[i][0],
            map: map,
            title: locations[i][1],
        });

        // Register a click event listener on the marker to display the corresponding infowindow content
        google.maps.event.addListener(marker, 'click', (function (marker, i) {

            return function () {
                infowindow.setContent(locations[i][2]);
                infowindow.open(map, marker);
            }

        })(marker, i));

        // Add marker to markers array
        markers.push(marker);
    }

    // Trigger a click event on each marker when the corresponding marker link is clicked
    $('.marker-link').on('click', function () {

        google.maps.event.trigger(markers[$(this).data('markerid')], 'click');
    });
}

initialize();
