我在使用 Google Map API 时遇到问题。我想在地图上绘制圆圈并在每个圆圈上创建鼠标悬停事件以打开显示时间值的信息窗口。
第一个问题是不同圈子的信息窗口内容不会改变。第二个问题是 infowindow 由于某种原因没有弹出。
有人可以帮忙吗?
谢谢
代码如下:
function initialize() {
data={};
data[0]={
center: new google.maps.LatLng(51.49799,-0.196145),
population: 1000,
time:"2013-03-01T03:31:18Z"
};
data[1]={
center: new google.maps.LatLng(51.496294,-0.188184),
population: 1000,
time:"2013-03-01T13:21:15Z"
};
data[2]={
center: new google.maps.LatLng(51.497817,-0.178313),
population: 1000,
time:"2013-03-04T04:03:50Z"
};
var mapOptions = {
zoom: 15,
center: new google.maps.LatLng(51.494438, -0.188907),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById('map_canvas'),
mapOptions);
var movingColour= '#FF0000';
var counter=0;
for (var city in data) {
// Construct the circle for each value in citymap. We scale population by 20.
//movingColour=ColorLuminance(movingColour, -0.005) ;
var populationOptions = {
strokeOpacity: 0.35,
strokeWeight: 2,
strokeColor:movingColour,
fillColor:movingColour ,
fillOpacity: 0.35,
map: map,
clickable:true,
center: data[city].center,
radius: data[city].population / 20
};
var circle = new google.maps.Circle(populationOptions);
var infowindow =new google.maps.InfoWindow({
content: data[city].time
});
google.maps.event.addListener(circle, 'mouseover', function(ev) {
alert(infowindow.content);
infowindow.open(map,circle);
});
counter++;
}
google.maps.event.addDomListener(window, 'load', initialize);
}
