我有一个点击事件,可以远程抓取坐标,将它们放在地图上,然后用折线连接它们。我有其他同样的点击事件,但希望将它们保存为单独的图层,以便用户可以切换以查看他们所做的每次点击。有没有人知道将它们分开进行分组的好方法呢?
到目前为止,这是我的代码:
drawPoints: function (points, color) {
$.each(points, function (key, val) {
var location = new google.maps.LatLng(val.Latitude, val.Longitude);
MyTest.addMarker(location, val.Name, val.Description);
MyTest.coordinates.push(location);
});
this.path = new google.maps.Polyline({
path: MyATest.coordinates,
strokeColor: color,
strokeOpacity: 1.0,
strokeWeight: 2
});
this.path.setMap(this.googlemap);
},
addMarker: function (location, title, html) {
var marker = new google.maps.Marker({
position: location,
map: this.googlemap,
title: title,
html: html
});
this.markers.push(marker);
},
// Removes the overlays from the map, but keeps them in the array
clearOverlays: function () {
if (this.markers) {
for (i in this.markers) {
this.markers[i].setMap(null);
}
}
},
// Shows any overlays currently in the array
showOverlays: function () {
if (this.markers) {
for (i in this.markers) {
this.markers[i].setMap(map);
}
}
},

你已经将它们保存在这个标记中 - 这是一个很好的开始。现在您需要做的就是为每个标记定义一个click
侦听器函数:
for(i in this.markers) {
google.maps.addListener(this.markers[i], function() {
this.markers[i].clicked = true; });
}
然后,每当用户想要仅切换他们点击的标记时,循环遍历您的标记(就像您正在做的那样)并将setMap设置为null,其中this.markers [i] .clicked === undefined。
