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 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));
}

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:

  1. 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"],
    
    ...
    

    ];

  2. 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>";
    

    }

  3. 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]));

  4. 希望有所帮助!
