我是JavaScript和Google Maps API v3的新手。我正在ASP.Net页面中尝试开发人员指南示例代码。地图按预期显示,但标记未加载。如果有人能发现我的错误,我会很感激:
<style type="text/css">
html, body, #map_canvas { margin: 0; padding: 0; height: 100%; }
</style>
<script type="text/javascript"
src="https://maps.googleapis.com/maps/api/js?sensor=false"></script>
<script type="text/javascript">
var map;
var myLatlng = new google.maps.LatLng(-41.2954168187213,174.767133718655 )
function initialize() {
var myOptions = {
zoom: 4,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("map_canvas"),
myOptions);
}
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: "Hello World!"
});
// The following set map made no difference.
//The constructor above should have been enough?
//marker.setMap(map);
//google.maps.event.addDomListener(window, 'load', initialize);
</script>
<body onload="initialize()">
<div id="map_canvas"></div>
</body>
答案 0 :(得分:2)
尝试将标记代码放在初始化函数中。否则,标记不会看到创建的地图。
