如何使用 API V3 每页显示多个 Google 地图 [英] How to Display Multiple Google Maps per page with API V3

问题描述

我有以下脚本.我想让两个地图都出现在页面上，但无论我尝试什么，我都只能显示第一个地图 initialize() ……第二个没有.有什么建议?(另外，我无法在代码中添加它，但是第一张地图显示在 <div id="map_canvas"></div><div id="route"><;/div>谢谢！

I have the following script. And I want to make both maps appear on the page, but no matter what I try I can only get the first map initialize() to display... the second one doesn't. Any suggestions? (also, I can't add it in the code, but the first map is being displayed in <div id="map_canvas"></div><div id="route"></div> Thanks!

<script type="text/javascript"> 
// Create a directions object and register a map and DIV to hold the 
// resulting computed directions

var map;
var directionsPanel;
var directions;

function initialize() {
  map = new GMap(document.getElementById("map_canvas"));
  map.setCenter(new GLatLng(41.1255275,-73.6964801), 15);
  directionsPanel = document.getElementById("route");
  directions = new GDirections(map, directionsPanel);
  directions.load("from: Armonk Fire Department, Armonk NY to: <?php echo $LastCallGoogleAddress;?> ");

  map.addControl(new GSmallMapControl());
  map.addControl(new GMapTypeControl());
}

</script> 


<div id="map_canvas2" style="width:200px; height:200px;"></div>
<div id="route2"></div>

<script type="text/javascript"> 
// Create a directions object and register a map and DIV to hold the 
// resulting computed directions

var map2;
var directionsPanel2;
var directions2;

function initialize2() {
  map2 = new GMap(document.getElementById("map_canvas2"));
  map2.setCenter(new GLatLng(41.1255275,-73.6964801), 15);
  directionsPanel2 = document.getElementById("route2");
  directions2 = new GDirections(map2, directionsPanel2);
  directions2.load("from: ADDRESS1 to: ADDRESS2 ");

  map2.addControl(new GSmallMapControl());
  map2.addControl(new GMapTypeControl());
}

</script> 

<script type="text/javascript">
function loadmaps(){
    initialize();
    initialize2();  
}
</script>

推荐答案

以下是我如何使用 Google Map API V3 在同一页面上生成多个地图.请注意，这是解决上述问题的现成代码.

Here is how I have been able to generate multiple maps on the same page using Google Map API V3. Kindly note that this is an off the cuff code that addresses the issue above.

HTML 位

<div id="map_canvas" style="width:700px; height:500px; margin-left:80px;"></div>
<div id="map_canvas2" style="width:700px; height:500px; margin-left:80px;"></div>

用于地图初始化的Javascript

Javascript for map initialization

<script type="text/javascript">
var map, map2;

function initialize(condition) {
    // create the maps
    var myOptions = {
        zoom: 14,
        center: new google.maps.LatLng(0.0, 0.0),
        mapTypeId: google.maps.MapTypeId.ROADMAP
    }
    map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);

    map2 = new google.maps.Map(document.getElementById("map_canvas2"), myOptions);
}
</script>
