我希望能够在Google地图中为气泡添加自定义信息。如何使用此代码完成此操作?

var locations = [

['Cronulla Beach', -34.028249, 151.157507, 3],

var map = new google.maps.Map(document.getElementById('map'), {
zoom: 10,
center: new google.maps.LatLng(-33.92, 151.25),
mapTypeId: google.maps.MapTypeId.ROADMAP
});
var infowindow = new google.maps.InfoWindow();
var marker, i;
for (i = 0; i < locations.length; i++) {
marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][1], locations[i][2]),
map: map
});
google.maps.event.addListener(marker, 'click', (function(marker, i) {
return function() {
infowindow.setContent(locations[i][0]);
infowindow.open(map, marker);
}
})(marker, i));
}

答案 0 :(得分:1)
你的代码看起来对我很好。不过,有很多方法可以进一步扩展它。这是一种方式:
向您的位置变量添加更多信息,以包含自定义信息中的信息,例如,指向图片的链接。
var locations = [
['Bondi Beach', -33.890542, 151.274856, 4, "http://mysite.com/images/beach.jpg"],
...
];
然后创建一个函数,为信息窗口提供他们需要的html格式。这个函数从实际的html中拉出html可能会更好,或者可能是从服务器通过ajax一次,但为了保持这个例子的简单,我将编写html内联:
function formatLocation(loc,img){
return "<img src='" + img + "' title=''> <b>" + loc + "</b>";
}
然后,当您设置信息窗口内容时,只需使用所需参数调用此函数:
infowindow.setContent(formatLocation(locations [i] [0],locations [i] [4]));
希望有所帮助!
