1、问题背景

     高德地图上标记多个标记，点击删除按钮，可以删除指定的几个点标记


2、实现源码

</div>
<script>
var map = new AMap.Map("container", {
resizeEnable: true,
center: [114.20495,30.407079],
zoom: 13
        });

AMap.event.addDomListener(document.getElementById('delMarker'), 'click', function() {
markers[1].setMap(null);
markers[3].setMap(null);
markers[5].setMap(null);
markers[7].setMap(null);
markers[9].setMap(null);
        }, false);
var markers = [], 
positions = [
                [114.195423,30.405821], 
                [114.203662,30.404636], 
                [114.220828,30.404784], 
                [114.222202,30.393976], 
                [114.201431,30.392051],
                [114.193448,30.413149],
                [114.220657,30.414777],
                [114.205379,30.414629],
                [114.202976,30.398492],
                [114.208812,30.400121]
            ];
for (var i = 0, marker; i < positions.length; i++) 
        {
marker = new AMap.Marker({
map: map,
icon: 'http://webapi.amap.com/theme/v1.3/markers/n/mark_b'+(i+1)+'.png',
position: positions[i]
            });
markers.push(marker);
        }
</script>
</body>
</html>


3、实现结果

（1）初始化时

（2）点击删除按钮
