我们在 ExtJs 容器中加载了 GE 插件。HTML 看起来像:
<script type="text/javascript" src="scripts/globe/Globe.js"></script>
<script type="text/javascript" src="scripts/ext/ext-all-debug.js"></script>
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load("earth", "1");
</script>
<script type="text/javascript">
Ext.onReady(function() {
Globe.initGlobe();
});
</script>
...
<body><!--Globe Panel is inserted here from Globe.js by Ext--></body>
javascript 类设置了一个容器,其中包含我们可以定位的 div:
this.globeContainingPanel = Ext.create('Ext.container.Container', {
...
renderTo: Ext.getBody(),
items: [{
{
xtype: 'panel',
region: 'center',
html: '<div id="map3d"></div>'
}
}]
});
然后让 GE 渲染到 div 面板:
window.google.loader.ApiKey = 'ABCDEFGHIJKLMNOPgoogle.earth.ex.key';
window.google.loader.KeyVerified = true;
window.google.earth.allowUsageLogging = false;
google.earth.createInstance('map3d', this.initCallback, this.failureCallback);
此外,请确保您的浏览器中安装了 Google 地球插件。
