Question

我正在使用Wordpress中一系列帖子的元数据生成地图。地图和点生成很好但是当我点击这些点时，infowindow总是在同一个地方生成，而不是在我点击的点上生成。有人可以帮忙解决这个问题，我在v2中工作正常但是我无法弄明白它。

使用以下内容在循环中生成地图：

function initialize(){
    var myLatlng = new google.maps.LatLng(45, -123);
     var myOptions = {
            zoom: 3,
            center: myLatlng,
            mapTypeId: google.maps.MapTypeId.ROADMAP
        };
    var map = new google.maps.Map(document.getElementById('travel_map'), myOptions);
    <?php if ( have_posts() ) :  while ( have_posts() ) : the_post();
        $my_post = get_post($post_id);
        $mapTitle  = $my_post->post_title;
        $lat = get_post_meta($post->ID, 'latitude', true); 
        $long = get_post_meta($post->ID, 'longitude', true);
        ?>

    var contentString = 'test';

    var infowindow = new google.maps.InfoWindow({
        content: contentString
    });

     var marker = new google.maps.Marker({
        position: new google.maps.LatLng(<?php echo $lat . ", " . $long ?>),
        map: map
     });

    google.maps.event.addListener(marker, 'click', function() {
      infowindow.open(map,marker);
    }); 

<?php endwhile;  ?>
<?php endif; ?>
}

此处介绍如何在页面上使用多个标记和多个infowindows。

这是实施：

<script type="text/javascript">

    var infowindow = null;
    var markers = [];
    function initialize(){
    var myLatlng = new google.maps.LatLng(45, -123);
     var myOptions = {
            zoom: 3,
            center: myLatlng,
            mapTypeId: google.maps.MapTypeId.ROADMAP
        };

    var map = new google.maps.Map(document.getElementById('travel_map'), myOptions);

    infowindow = new google.maps.InfoWindow({
        content: "holding..."
    });

    <?php if ( have_posts() ) :  while ( have_posts() ) : the_post();
        $my_post = get_post($post_id);
        $mapTitle  = $my_post->post_title;
        $lat = get_post_meta($post->ID, 'latitude', true); 
        $long = get_post_meta($post->ID, 'longitude', true);
        ?>

    var marker = new google.maps.Marker({
        position: new google.maps.LatLng(<?php echo $lat . ", " . $long ?>),
        map: map,
        html: "<b><?php echo $mapTitle; ?></b><br><br><?php echo $my_post; ?>"
    });

    markers.push(marker);

    google.maps.event.addListener(marker, 'click', function () {
        infowindow.setContent(this.html);
        infowindow.open(map, this);
    });


<?php endwhile;  ?>
<?php endif; ?>
}
</script>

让infowindows在循环中工作
