Question

我使用google map api创建了地图视图，使用google.maps.Circle圆圈在地图上打印时将标记更改为圆圈，但没有任何问题，但我无法在其中添加标签或文字。我该如何解决这个问题。

以下是我用来打印圆圈的代码

   function initialize() {

        var frrlanser_marker = {
            strokeColor: '#FF0000',
            strokeOpacity: 0.8,
            strokeWeight: 2,
            fillColor: '#FF0000',
            fillOpacity: 0.35,
            radius: 60 * 100
        };



        var latlng = new google.maps.LatLng(6.951974, 80.720160);
        var myOptions = {
            scrollwheel: false,
            zoom: 10,
            center: latlng,
            mapTypeId: google.maps.MapTypeId.ROADMAP
        };

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

<?php foreach($results as $val): ?>
<?php if($val->geo_location != ""): ?>

      <?php if($val->fontUserTypeId == 1) { ?>
        var fill_color_val = '#3888ff';
      <?php } else { ?>
        var fill_color_val = '#70d04f';
     <?php  } ?>




   <?php $LatLng = explode(",", $val->geo_location); ?>

    var latitude = <?php echo $LatLng[0]; ?>;
    var lontitude = <?php echo $LatLng[1]; ?>;

    var myLatLng = {lat: latitude, lng: lontitude};

    var marker = new google.maps.Marker({
        position: myLatLng,
        map: map
    });

       // Add circle overlay and bind to marker
        var circle = new google.maps.Circle({
            map: map,
            radius: 3200,    // 10 miles in metres
            fillColor: fill_color_val,
            strokeColor: '#FFFFFF',
            strokeWeight: 2,
            fillOpacity: 1,
        });
        circle.bindTo('center', marker, 'position');

        marker.setVisible(false);

    }

    google.maps.event.addDomListener(window, "load", initialize);

您可以在圆圈上添加带有所需标签/文字的InfoBox。
