使用Google Maps API v3禁用兴趣点信息窗口

Question

我有一个带有信息气泡和自定义标记的自定义地图.当我放大兴趣点,如公园和大学出现,当我点击信息窗口打开.如何禁用信息窗口？

我的代码如下:

var geocoder;
var map;
var infoBubble;
var dropdown = "";
var gmarkers = [];

var hostel_icon = new google.maps.MarkerImage('/resources/hostel_blue_icon.png',
new google.maps.Size(28,32),
new google.maps.Point(0,0),
new google.maps.Point(14,32));

var bar_icon = new google.maps.MarkerImage('/resources/bar_red_icon.png',
new google.maps.Size(28,32),
new google.maps.Point(0,0),
new google.maps.Point(14,32));

var icon_shadow = new google.maps.MarkerImage('/resources/myicon_shadow.png',
new google.maps.Size(45,32),
new google.maps.Point(0,0),
new google.maps.Point(12,32));

var customIcons = {
    hostel: {
        icon: hostel_icon,
        shadow: icon_shadow
    },
    bar: {
        icon: bar_icon,
        shadow: icon_shadow
    }
};

function initialize() {
    var latlng = new google.maps.LatLng(12.82364, 26.29987);
    var myMapOptions = {
        zoom: 2,
        center: latlng,
        panControl: false,
        scaleControl: true,
        mapTypeId: google.maps.MapTypeId.TERRAIN,
        mapTypeControlOptions: {style: google.maps.MapTypeControlStyle.HORIZONTAL_BAR},
        navigationControlOptions: {style: google.maps.NavigationControlStyle.DEFAULT}
    }
    map = new google.maps.Map(document.getElementById("map_canvas"), myMapOptions);

    infoBubble = new InfoBubble({
        shadowStyle: 0,
        padding: 0,
        backgroundColor: 'rgb(57,57,57)',
        borderRadius: 5,
        arrowSize: 10,
        borderWidth: 1,
        maxWidth: 400,
        borderColor: '#2c2c2c',
        disableAutoPan: false,
        hideCloseButton: true,
        arrowPosition: 50,
        backgroundClassName: 'phoney',
        arrowStyle: 0
    });

    // Change this depending on the name of your PHP file
    downloadUrl("phpsqlajax_genxml_2.php", function(data) {
        var xml = parseXml(data);
        var markers = xml.documentElement.getElementsByTagName("marker");
        for (var i = 0; i < markers.length; i++) {
            var bar_name = markers[i].getAttribute("bar_name");
            var hostel_name = markers[i].getAttribute("hostel_name");
            var street = markers[i].getAttribute("street");
            var city = markers[i].getAttribute("city");
            var postcode = markers[i].getAttribute("postcode");
            var country = markers[i].getAttribute("country");
            var page = markers[i].getAttribute("page");
            var map_photo = markers[i].getAttribute("map_photo");
            var type = markers[i].getAttribute("type");
            var category = markers[i].getAttribute("category");
            var point = new google.maps.LatLng(
            parseFloat(markers[i].getAttribute("lat")),
            parseFloat(markers[i].getAttribute("lng")));

            var html = '<div class="infowindow"><div class="iwPhoto" style="width: 105px; height: 65px;">' + "<a href='" + page + "'><img src='" + map_photo + "' alt=''/></a>" + '</div><div class="iwName" style="height: 24px;">' + "<a href='" + page + "'>" + hostel_name + "</a>" + '</div><div class="iwCategory" style="height: 15px;">' + category + '</div><div class="iwCity" style="height: 29px;">' + "<a href='" + page + "'>" + city + "</a>" + '<div class="iwArrow" style="width: 29px; height: 29px;">' + "<a href='" + page + "'><img src='/resources/arrow.png'/></a>" + '</div></div></div>';

            var icon = customIcons[type] || {};
            var marker = new google.maps.Marker({
                map: map,
                position: point,
                icon: icon.icon,
                shadow: icon.shadow,
                title: bar_name
            });
            marker.bar_name = bar_name;
            marker.category = category;
            bindInfoBubble(marker, map, infoBubble, html, bar_name);

            gmarkers.push(marker);

            str = '<option selected> - Select a club - </option>';
            for (j=0; j < gmarkers.length; j++){
                str += '<option value="'+gmarkers[j].bar_name+'">'+gmarkers[j].bar_name+', '+gmarkers[j].category+'</option>';
            }
            var str1 ='<form name="form_city" action=""><select style="width:150px;" id="select_city" name="select_cityUrl" onchange="handleSelected(this);">';
            var str2 ='</select></form>';
            dropdown = str1 + str + str2;
        }
        document.getElementById("dd").innerHTML = dropdown;
    });
}

function handleSelected(opt) {
    var indexNo = opt[opt.selectedIndex].index;
    google.maps.event.trigger(gmarkers[indexNo-1], "click");
}

function bindInfoBubble(marker, map, infoBubble, html) {
    google.maps.event.addListener(marker, 'click', function() {
        infoBubble.setContent(html);
        infoBubble.open(map, marker);
        google.maps.event.addListener(map, "click", function () {

更新Google Maps JavaScript API V3

您可以在MapOptions中将clickableIcons设置为false.这将保留POI图标,但可以根据需要禁用信息窗口.

function initialize() {
    var myMapOptions = { clickableIcons: false }
}

Answer 2

查看可点击的其他答案:false answer.

但是,如果你想点击,但没有信息窗口,呼吁stop()在event防止信息窗口无法显示,但仍获得位置信息:

map.addListener('click', function (event) {
  // If the event is a POI
  if (event.placeId) {

    // Call event.stop() on the event to prevent the default info window from showing.
    event.stop();

    // do any other stuff you want to do
    console.log('You clicked on place:' + event.placeId + ', location: ' + event.latLng);
  }
}

有关详细信息,请参阅文档.

其他选项:完全删除POI图标,而不仅仅是infoWindow:

var mapOptions = {
  styles: [{ featureType: "poi", elementType: "labels", stylers: [{ visibility: "off" }]}]
};
var map = new google.maps.Map(document.getElementById('map-canvas'),
    mapOptions);

Answer 3

您可以通过创建没有感兴趣点标签的样式化地图来完成此操作.这样可以在地图上保留地形和其他不错的信息,但会删除标记.

  var remove_poi = [
    {
      "featureType": "poi",
      "elementType": "labels",
      "stylers": [
        { "visibility": "off" }
      ]
    }
  ]

map.setOptions({styles: remove_poi})

Answer 4

您可以考虑以下方法来禁用POI信息窗口:

function disablePOIInfoWindow(){
    var fnSet = google.maps.InfoWindow.prototype.set;
    google.maps.InfoWindow.prototype.set = function () {
    };
}

例

function initMap() {
    var latlng = new google.maps.LatLng(40.713638, -74.005529);
    var myOptions = {
        zoom: 17,
        center: latlng,
        mapTypeId: google.maps.MapTypeId.ROADMAP
    };
    
    var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
    disablePOIInfoWindow();  
}

function disablePOIInfoWindow(){
    var fnSet = google.maps.InfoWindow.prototype.set;
    google.maps.InfoWindow.prototype.set = function () {
       alert('Ok');
    };
}


google.maps.event.addDomListener(window, 'load', initMap);

html, body {
   height: 100%;
   margin: 0;
   padding: 0;
}

#map_canvas {
   height: 100%;
}

<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<div id="map_canvas"></div>

以上示例影响所有信息窗口,因此如果您只需要禁用POI信息窗口,那么我们可以引入标志来确定它是否是POI信息窗口:

function disablePOIInfoWindow(){
    var fnSet = google.maps.InfoWindow.prototype.set;
    google.maps.InfoWindow.prototype.set = function () {
        if(this.get('isCustomInfoWindow'))
           fnSet.apply(this, arguments);
    };
}

例

function initMap() {
    var latlng = new google.maps.LatLng(40.713638, -74.005529);
    var myOptions = {
        zoom: 17,
        center: latlng,
        mapTypeId: google.maps.MapTypeId.ROADMAP
    };
    var infowindow = new google.maps.InfoWindow({
        content: ''
    });
    infowindow.set('isCustomInfoWindow',true);
    var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
    disablePOIInfoWindow();
    google.maps.event.addListener(map, 'click', function (event) {
        infowindow.setContent(event.latLng.lat() + "," + event.latLng.lng());
        infowindow.setPosition(event.latLng);
        infowindow.open(map, this);
    });
    
}

function disablePOIInfoWindow(){
    var fnSet = google.maps.InfoWindow.prototype.set;
    google.maps.InfoWindow.prototype.set = function () {
        if(this.get('isCustomInfoWindow'))
           fnSet.apply(this, arguments);
    };
}


//google.maps.event.addDomListener(window, 'load', initMap);

html, body {
   height: 100%;
   margin: 0;
   padding: 0;
}

#map_canvas {
   height: 100%;
}

<div id="map_canvas"></div>
<script src="https://maps.googleapis.com/maps/api/js?callback=initMap"
            async defer></script>
