Question

我正在尝试检测圆圈中的标记位置。标记从数据库中获取的纬度和经度。我设法检测到标记位置。但是仅来自最后一个标记的警报。如何为每个标记/圆圈显示警报？

查找更多详细信息，请参阅此处：link

尝试将标记拖动到每个圆圈。

提前致谢，抱歉我的英语不好：）

代码：

    <script type="text/javascript">
function init_terminal() {
  var mapOptions = { center: new google.maps.LatLng(-6.832858,107.953184), zoom: 10,
      mapTypeId: google.maps.MapTypeId.ROADMAP,
      scaleControl: true
      };
    map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);

var dragable_marker = new google.maps.Marker({
    position : new google.maps.LatLng(-6.832858,107.953184),
    map : map,
    draggable : true

    }
    else {

    document.getElementById("lngbox").value = this.getPosition().lng();
    }
});
<?php }?>
var kmlOptions = {preserveViewport: 1};
<?php

    layersemua.setMap(map,this);
    document.getElementById('lihatsemua').checked = true; 
    <?php }?>
}

    </script>

要检测两个圆圈，请为它们指定唯一名称（circle1，circle2）或使用函数闭包将侦听器与圆圈相关联。

检测圆圈gmap3中的标记，仅从数据库返回最后一个标记
