我想用谷歌地图v3,如果你放大高于15,地图显示标记位置,但当你缩小我想隐藏标记.我找不到任何功能来做到这一点.到目前为止,对我来说没有任何作用.

所以这是我的脚本:

<script type="text/javascript">
        function initialize() {
            var mapOptions = {
              zoom: 15,
              center: new google.maps.LatLng(52.429236, 6.281255),
              mapTypeId: google.maps.MapTypeId.ROADMAP
            };
            var map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);

            setMarkers(map, points);

            google.maps.event.addListener(map, 'zoom_changed', function()
{
                        if (map.getZoom() > 15) {
                                setMarkers(map, points);
                        } else {
                                hideMarkers(map, points);

                        }
                           }); 

        }


        var points = [
            ['Location 1', 52.420891, 6.280204],
            ['Location 2', 52.420125, 6.279131],
            ['Location 3', 52.420125, 6.240125]
        ];


        function setMarkers(map, locations) {
            var image = new google.maps.MarkerImage('../images/map/beachflag.png',
            new google.maps.Size(20, 32),
            new google.maps.Point(0,0),
            new google.maps.Point(0, …

我正在为我的图表使用jQuery Plot.我有一个列表,其中包含来自数据库的一些时间戳和值.

我想将我的时间戳转换为H:i:s格式.结果从10-05-2012 08:57:45到10-05-2012 09:03:40.
