我正在尝试将 Bing Maps 7.0 API 与延迟加载一起使用,因为 onScriptLoad 参数似乎支持这一点。我使用了这个最小的测试用例:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Bing Maps Test</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
</head>
<body>
<div id='mapDiv' style="position:absolute; width:600px; height:400px;"></div>
<script type="text/javascript">
function initMap() {
console.log('Callback called');
var map = new Microsoft.Maps.Map(document.getElementById("mapDiv"), {credentials:"<API KEY>"});
}
function loadMapControl()
{
var script = document.createElement("script");
script.setAttribute("src", "http://dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=7.0&onScriptLoad=initMap");
script.setAttribute("type", "text/javascript");
document.documentElement.firstChild.appendChild(script);
console.log('Tag appened');
}
setTimeout(loadMapControl, 1000);
</script>
</body>
</html>
回调按预期调用,但 Firebug 向我抛出Microsoft.Maps.Map is not a constructor
错误。即使我在通过 setTimeout 调用回调后将地图创建延迟了 10 秒。
然而,必应文档中的简单示例运行良好:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Bing Maps Test</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<script charset="UTF-8" type="text/javascript" src="http://ecn.dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=7.0"></script>
</head>
<body>
<div id='mapDiv' style="position:absolute; width:600px; height:400px;"></div>
<script type="text/javascript">
var map = new Microsoft.Maps.Map(document.getElementById("mapDiv"), {credentials:",API KEY>"});
</script>
</body>
</html>
有没有人成功让 API 7.0 与延迟加载一起工作?
谢谢。
