问题描述
我有一个带有信息气泡和自定义标记的自定义地图.当我放大公园和大学等兴趣点时，当我单击时，会打开一个信息窗口.如何禁用信息窗口?
I have a custom map with an information bubble and custom markers. When I zoom into points of interest such as parks and universities appear and when I click an information window opens. How do I disable the info window?
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 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({

});

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 () {
infoBubble.close();
});
});
}
function downloadUrl(url, callback) {
var request = window.ActiveXObject ?
new ActiveXObject('Microsoft.XMLHTTP') :
new XMLHttpRequest;
request.onreadystatechange = function() {
if (request.readyState == 4) {
request.onreadystatechange = doNothing;
callback(request.responseText, request.status);
}
};
request.open('GET', url, true);
request.send(null);
}
function parseXml(str) {
if (window.ActiveXObject) {
var doc = new ActiveXObject('Microsoft.XMLDOM');
doc.loadXML(str);
return doc;
} else if (window.DOMParser) {
return (new DOMParser).parseFromString(str, 'text/xml');
}
}
function doNothing() {}
推荐答案
UPDATE Google Maps JavaScript API V3
您可以在 MapOptions 中将 clickableIcons 设置为 false.这将保留 POI 图标，但会根据需要禁用信息窗口.
You can set clickableIcons to false in MapOptions. This will keep the POI icons but disable the infowindows just as you want.
function initialize() {
var myMapOptions = { clickableIcons: false }
}
