更新/重新加载标记而无需重新加载谷歌地图

我正在使用以下代码生成标记引脚.它加载完美,但在这张地图的左边我有过滤器.如何在不重新加载地图的情况下重新加载标记？这已经引起了一些挫折,所以任何帮助将不胜感激.

非常感谢,

    //Google map results
        var contentStrings = [];
        var infowindow = new google.maps.InfoWindow();
        var mapinited = false;
        var map;
        var myOptions = {
          zoom: 11,
          center: myLatlng,
          mapTypeId: google.maps.MapTypeId.ROADMAP
        }
        var currentinfobox;
        var myLatlng;
        var markersArray=[];
        var LatLngList = [];

$().ready(function() {

    //reinit search 
    if (window.location.hash) {
        submitForm(window.location.hash.replace('#',''));
    }
    else if (readCookie('sf')) {
            //submitForm(readCookie('sf'));
    }

    //init map
    $('#map_view').click(function() {
        if (mapinited) {
            return;
        } else {
            mapinited = true;
            initMap();
        }



    function initMap() {
            locate(["Ireland"],function(result) {
        map = new google.maps.Map(document.getElementById("search_map"), myOptions);
        myLatlng = new google.maps.LatLng(result.lat(),result.lng());

              var key =0;

               $.each(map_results, function(key, value){
        LatLngList[key] = new google.maps.LatLng(value.lat,value.long)
        contentStrings[key] =

                map_results="";

        google.maps.event.addListener(infowindow, 'domready', function() {

        });

        var zoomChangeBoundsListener = google.maps.event.addListener(map, 'zoom_changed', function() {
            if (this.getZoom() > 14) // Change max/min zoom here
                this.setZoom(14);        
            google.maps.event.removeListener(zoomChangeBoundsListener);
        });
        var infoboxlistener = google.maps.event.addListener(map, 'zoom_changed', `enter code here`function() {

        loadMapInit(LatLngList,contentStrings);

    });
    }

    });

  });

希望这能回答你的要求:

创建标记时,可以使用"map"参数设置其地图并显示它.或者,如果要将其绑定到过滤器,则可以忽略地图参数并稍后使用marker.setMap(map).

// To add the marker to the map, use the 'map' property
var marker = new google.maps.Marker({
    position: myLatlng,
    map: map,
    title:"Hello World!"
});

如果要"删除"和"添加"带事件的标记,可以使用marker.setMap(null)删除标记和marker.setMap(map)以重新添加它.

var marker = new google.maps.Marker({
    position: myLatlng,
    title:"Hello World!"
});

// To add the marker to the map, call setMap();
marker.setMap(map);

// To remove the marker from the map
marker.setMap(null);

更新:因此,如果您想"重新加载"标记,您可以遍历当前活动标记的数组,将其地图设置为null,然后在地图上重置它们.
