我有一个简单的谷歌地图 v3,上面附有一个标记和信息窗口。
如果我单击标记,则信息窗口会自动显示并映射平移以适应视图中的信息窗口,但是如果我尝试在页面加载时触发单击以打开信息窗口,则信息窗口会打开但不会发生平移。
触发是这样完成的:
google.maps.event.trigger(marker, 'click');
如果我将上面的代码移动到一个函数中并使用 setTimeout 500 调用它,那么平移也会发生。
我在 API 中进行了挖掘,但找不到导致按需自动平移的功能。有没有办法不使用超时?为什么超时有帮助?
谢谢
这是不平移的示例:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<style type="text/css">
html { height: 100% }
body { height: 100%; margin: 0; padding: 0 }
#map-canvas { width: 400px; height: 320px }
</style>
<script type="text/javascript"

<script type="text/javascript">
function initialize() {
var myLatlng = new google.maps.LatLng(42.6620233,-78.4250679);
var mapOptions = {
center: myLatlng,
zoom: 7,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map-canvas"),
mapOptions);
var contentString = '<div style="width: 200px; height: 100px;">Testing</div>';
var infowindow = new google.maps.InfoWindow({
content: contentString
});
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title:"Hello World!"
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map,marker);
});
google.maps.event.trigger(marker, 'click');
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<div id="map-canvas"/>
</body>
</html>
这是一个平移但只有超时的:

<style type="text/css">

</style>

<script type="text/javascript">

var marker;

zoom: 7,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map-canvas"),
mapOptions);
var contentString = '<div style="width: 200px; height: 100px;">Testing</div>';
var infowindow = new google.maps.InfoWindow({
content: contentString
});
marker = new google.maps.Marker({
position: myLatlng,
map: map,
title:"Hello World!"
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map,marker);
});
setTimeout('pop()', 500);
//google.maps.event.trigger(marker, 'click');
//infowindow.open(map,marker);
//map.pan();
}
google.maps.event.addDomListener(window, 'load', initialize);
function pop() {
google.maps.event.trigger(marker, 'click');
}
//setTimeout('pop()', 500);
