Google Maps-在Safari中某些缩放级别上奇怪的垂直和水平线 [英] Google Maps - Strange vertical and horizontal lines at certain zoom levels in Safari
问题描述
我在使用Google地图时遇到了问题,这些奇怪的线在Safari中以某些缩放级别出现在我的地图上.如果我调整浏览器的大小,它们会消失一秒钟,然后再返回.我认为这与Google Map处于具有"margin:0 auto;"的容器内有关.当我在全幅Google Map上对其进行测试时,没有任何问题.
I'm having an issue with Google Maps where these weird lines are coming up over my map at certain zoom levels in Safari. If I resize my browser they go away for a second then come back. I think it's to do with the Google Map being inside a container which has "margin: 0 auto;" as I tested it in a full width Google Map and there were no issues.

HTML:
<div id="map"></div>
JS:
var map;
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(-38.255338, 144.34334),
zoom: 10,
mapTypeId: google.maps.MapTypeId.ROADMAP,
draggable: true,
zoomControl: true,
scrollwheel: false,
disableDefaultUI: true,
};
map = new google.maps.Map(document.getElementById("map"), mapOptions);
var location = new google.maps.LatLng(-38.272048, 144.479249);
var icon1 = 'https://upload.wikimedia.org/wikipedia/commons/thumb/0/0e/ISO_7010_E003_-_First_aid_sign.svg/2000px-ISO_7010_E003_-_First_aid_sign.svg.png';
var markerImage1 = {
url: icon1,
scaledSize: new google.maps.Size(25, 25),
origin: new google.maps.Point(0, 0),
anchor: new google.maps.Point(10, 12)
};
var marker = new google.maps.Marker({
position: location,
map: map,
icon: markerImage1
});
}
initialize();
CSS:
#map {
background-color: #000;
height: 500px;
margin: 0 auto;
width: 350px;
}
推荐答案
看起来无论在画布上渲染图标是一个问题.在markerOptions中设置{optimized: false}
即可对其进行修复.
Looks like it is a problem with whatever is rendering the icon on canvas. Setting {optimized: false}
in the markerOptions fixes it.
代码段:
var map;
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(-38.255338, 144.34334),
zoom: 10,
mapTypeId: google.maps.MapTypeId.ROADMAP,
draggable: true,
zoomControl: true,
scrollwheel: false,
disableDefaultUI: true,
};
map = new google.maps.Map(document.getElementById("map"), mapOptions);
var location = new google.maps.LatLng(-38.272048, 144.479249);
var markerImage1 = {
url: icon1,
scaledSize: new google.maps.Size(25, 25),
origin: new google.maps.Point(0, 0),
anchor: new google.maps.Point(10, 12)
};
var marker = new google.maps.Marker({
position: location,
map: map,
icon: markerImage1,
optimized: false // <-- this fixes the artifacts
});
}
google.maps.event.addDomListener(window, 'load', initialize);
