问题描述
我试图在点击标记上添加一个半径圆。我可以让圈子出现没有任何问题。我把这个圆放在它自己的函数中,然后将它附加到一个单击事件中。由于某种原因,它似乎并没有工作。任何人都可以照亮这种情况吗?
I am trying to add a radius circle around a marker on click. I can get the circle to appear without any issues. I have put the circle within it's own function and then attached it to a click event. For some reason it does not seem to work though. Can anyone shine any light on the situation please?

'zoom': 6,
'center': centerLatlng,
'mapTypeId': google.maps.MapTypeId.ROADMAP
});
// Marker Icons Implementation
markers = new google.maps.Marker({
position: centerLatlng,
map: map,
title: 'Center of Map'
});
// Add click event listenecal
calcRadius(60000);
};
function calcRadius(radiusVal)
{
//console.log(document.getElementById("#radioBtn1").value);
google.maps.event.addListener(map, "click", function () {
circle = new google.maps.Circle({
map: map
radius : 9000,
strokeColor : '#BBD8E9',
strokeWeight : 2
});
console.log(circle);
circle.bindTo('center', marker, 'position');
});
}
google.maps.event.addDomListener(window, 'load', initialize);
推荐答案
将点击侦听器添加到标记中。
Add the click listener to the marker.
代码:
var circle, map;
function initialize()
{
var centerLatlng = new google.maps.LatLng(38.061067,-104.414062);
map = new google.maps.Map(document.getElementById('map'), {
'zoom': 6,
'center': centerLatlng,
'mapTypeId': google.maps.MapTypeId.ROADMAP
});
// Marker Icons Implementation
markers = new google.maps.Marker({
position: centerLatlng,
map: map,
title: 'Center of Map'
});
// Add click event listenecal
calcRadius(markers, map, 60000);
};
function calcRadius(marker, map, radiusVal)
{
//console.log(document.getElementById("#radioBtn1").value);
google.maps.event.addListener(marker, "click", function () {
circle = new google.maps.Circle({
map: map,
fillColor : '#BBD8E9',
fillOpacity : 0.3,
radius : radiusVal,
strokeColor : '#BBD8E9',
strokeOpacity : 0.9,
strokeWeight : 2
});
// console.log(circle);
circle.bindTo('center', marker, 'position');
});
}
google.maps.event.addDomListener(window, 'load', initialize);
