我们有一个显示一系列或标记的 v3 地图，但是今天 (16/08/12) Chrome 和 Safari 已停止渲染除一个之外的所有内容，并且缩放功能现已失效。在 IE 和 FF 中一切都很好。
function placeMarker(location)
{
// first remove all markers if there are any
deleteOverlays();
var marker_icon = new google.maps.MarkerImage("http://chart.apis.google.com/chart?chst=d_map_pin_icon&chld=info%7CFFFF00",
new google.maps.Size(21, 34),
new google.maps.Point(0,0),
new google.maps.Point(6, 20));
var marker = new google.maps.Marker({
position: location,
icon: marker_icon,
map: map,
draggable: true
});
// add marker in markers array
markersArray.push(marker);
$('#lat').val(location.lat().toFixed(6));
$('#lon').val(location.lng().toFixed(6));
}
// Deletes all markers in the array by removing references to them
function deleteOverlays()
{
if (markersArray) {
for (i in markersArray) {
markersArray[i].setMap(null);
}
markersArray.length = 0;
}
}

这是定义标记后立即包含的 js 的最后一部分：
