关闭特定的信息窗口/隐藏折线Google Maps API v3
[英]close specific infoWindow / Hide Polyline Google maps api v3
问题描述
我需要能够显示隐藏单个折线及其关联的infoWindow +标记。
这是我的代码，目前clearOverlays（）函数隐藏所有标记，我需要能够使用底部链接中的hideRoutePath（）函数隐藏特定标记。.我对此有任何帮助用尽了主意..谢谢！

看起来您只需要将路由声明为全局变量即可。 将以下内容添加到脚本顶部
var bromley_route638, bromley_route638Run2;

这是完整的JSFiddle演示：
这是一种实现方法，但是可以优化代码。 首先，我添加了两个新功能removeMarker和checkMarker。 removeMarker，从地图以及数组中删除一个标记，这样您就不会在同一地点留下多个重复的标记。 checkMarker，检查标记是否已经在地图上和全局markersArray中。 如果返回true，否则返回false。 我们使用checkMarker来确保不会在同一latlng上创建标记的多个实例。 在您的情况下，它是标记路线1和标记路线2。
//remove specific marker from map
function removeMarker(myMark) {
if (markersArray) {
for (var i in markersArray) {
if (myMark == markersArray[i]['number']) {
console.log(markersArray[i]['number']);
markersArray[i].setMap(null);
markersArray.splice(i,1); //removes marker from array
break;
}
}
}
}
//check if marker already exist on map
function checkMarker(number){
if(markersArray){
for(var i in markersArray){
if(markersArray[i]['number'] == number)
return true;
}
} else
return false;
}
然后，我使用checkMarker添加一个标记检查器，以确保我们不会使用其关联路线创建双重标记，并且还为您的制造商提供了唯一的“数字”标识符。 其中1是marker1，2是marker2。 这两个mod应该在showRoutePath_1和showRoutePath_2函数中：
//check if marker1 already on map if true do nothing
if(checkMarker(1)) //check if marker already in global marker array/map if marker 2 replace 1 with 2
return;
position = new google.maps.LatLng(51.41859298, 0.089179345);
var infowindow = new google.maps.InfoWindow({
content: "Beaverwood School"
});
var marker = new google.maps.Marker({
position: position,
map: map
});
marker['number'] = 1; //Here is the unique identifier we assign. if marker 2 replace 1 with 2
最后但并非最不重要的一点是，我通过添加标识符参数“ number”来更改您的hideRoutePath，并使用removeMarker函数隐藏/删除关联的路径和标记：
function hideRoutePath(number) {
if (number == 1) {
//clearOverlays();
bromley_route638.setMap(null);
}
else if (number == 2) {
//clearOverlays();
bromley_route638Run2.setMap(null);
}
removeMarker(number);
}
