有人可以帮我解释如何将自定义图像标记绑定到此脚本吗？

XML很简单：
<markers>
<marker markerimage="https://developers.google.com/maps/documentation/javascript/examples/full/images/beachflag.png" id="value" lat="value" lng="value" country="value" />
我曾尝试将“icon：image”添加到创建标记部分，但我无法弄清楚。我试图将“icon：image”添加到创建标记部分，但我无法想象它出来了。
答案 0 :(得分：0)
您需要将自定义图标传递到createMarker功能：
// create the marker
var marker = createMarker(point, country + " " + id, html, marker_image);
更新createMarker功能：
// A function to create the marker and set up the event window function
function createMarker(latlng, name, html, icon) {
var contentString = html;
var marker = new google.maps.Marker({
position: latlng,
icon: icon,
// map: map,
zIndex: Math.round(latlng.lat() * -100000) << 5
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.setContent(contentString);
infowindow.open(map, marker);
});
// save the info we need to use later for the side_bar
gmarkers.push(marker);
// add a line to the side_bar html
side_bar_html += '<a href="javascript:myclick(' + (gmarkers.length - 1) + ')">' + name + '<\/a><br>';
}
