让信息窗口在循环中工作 - Getting infowindows to work within the loop

Getting infowindows to work within the loop

我正在用Wordpress中一系列帖子的元数据生成一个地图。地图和点生成得很好，但当我点击点时，信息窗口总是在同一个地方生成，而不是在我点击的点上。有人能帮我吗，我在v2中运行得很好，但我无法计算出3。

在循环中生成的地图如下：

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; ?>
}

这里介绍了如何在页面上使用多个标记和多个信息窗口。

下面是实现：

<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>
