我有以下代码使用javascript v3 api在Google地图上突出显示某个区域。
// Maps
$(document).ready(function(){
if($(document).find("map_canvas"))
Maps.init();
});
var Maps = {};
//The map to display
Maps.map;
//List of markers
Maps.markers = new Array();
Maps.markers.previous;
Maps.lines = new Array();
Maps.lines.toStart;
Maps.area;
//init the map
Maps.init = function() {
var mapOptions = {
center: new google.maps.LatLng(-39.483715,176.8942277),
zoom: 15,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
Maps.map = new google.maps.Map(document.getElementById("map_canvas"), mapOptions);
google.maps.event.addListener(Maps.map, 'click', function(event){Maps.addMarker(event.latLng);});
}
//Add a marker to the maps
Maps.addMarker = function(latLng){
var marker = new google.maps.Marker({
position: latLng,
map: Maps.map
});
Maps.markers.push(latLng);
console.log(Maps.markers.length);
if(Maps.markers.length > 1){
Maps.drawLine([Maps.markers.previous, latLng]);
}
Maps.markers.previous = latLng;
}
Maps.drawLine = function(path){
var Line = new google.maps.Polyline({
path: path,
strokeColor: "#FF0000",
strokeOpacity: 1.0,
strokeWeight: 2
});
Line.setMap(Maps.map);
if(Maps.markers.length > 2){
if(Maps.lines.toStart != null)
Maps.lines.toStart.setMap(null);
Maps.lines.toStart = new google.maps.Polyline({
path: [path[path.length - 1], Maps.markers[0]],
strokeColor: "#0000FF",
strokeOpacity: 1.0,
strokeWeight: 2
});
Maps.lines.toStart.setMap(Maps.map);
if(Maps.area != null)
Maps.area.setMap(null);
Maps.area = new google.maps.Polygon({
paths: Maps.markers,
strokeColor: "#000000",
strokeOpacity: 0,
strokeWeight: 0,
fillColor: "#FF0000",
fillOpacity: 0.35
});
Maps.area.setMap(Maps.map);
}
}
它完美地按预期工作,产生一个像这样的结果......
但问题是,我需要在多边形内添加标记,原因很明显。当我点击希望添加标记的多边形时,多边形似乎是获得点击而不是地图。反正有没有绕过这个?或者只有地图才能获得点击次数?
