本文关键字：LatLng maps google defined API v3- 错误 表达式 谷歌地图 结果 类型      更新时间：2023-09-26

我正在创建一个静态html页面来显示数据中的多个位置。我刚刚复制了其中一个样本，正在反向工作，但我在Safari检查器中遇到了以下错误：

main.js:1SyntaxError: Parse error
sample.htm:10TypeError: Result of expression 'google.maps.LatLng' [undefined] is not a constructor.

这是我的html代码：

function initialize() {
var myLatlng = new google.maps.LatLng(-30.2965590,153.1152650);
var myLatlng1 = new google.maps.LatLng(-30.2956470,153.1123707);
var myLatlng2 = new google.maps.LatLng(-30.2864430,153.1360230);
var myOptions = {
zoom: 13,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
icon: 'http://www.google.com/intl/en_us/mapfiles/ms/icons/blue-dot.png',
title:"Original Location"     });   
var marker = new google.maps.Marker({
position: myLatlng1,
map: map,
title:"Tom Cruise"     }); 
var marker = new google.maps.Marker({
position: myLatlng2,
map: map,
title:"Lady Gaga"     }); 
} 
</script> 
</head> 
<body onLoad="initialize()">   
<div id="map_canvas"></div> 
</body> 
</html>

我不确定我在这里做错了什么——它实际上在Windows上的IE v8中有效，但在Safari中无效，我需要让它同时适用。

为您的谷歌地图请求添加回调函数。它将在谷歌加载所需的所有内容后执行。

hi请使用JQuery使用此代码`
