在web页面中，加载google earth plugin之后，就会出现google earth永久保持在最上层，即使用div封装，设置z-index都无法实现其他控件出现在google earth 的上层。
不过，现在可以使用http://prototype-window.xilinus.com上编写的prototype window就可以实现，在web页面，弹出一个新的dialog覆盖在google earth上面。
用法如下：
It's easy to use, just include two javascripts and one css (more if you want different skins).
<script type="text/javascript" src="/javascripts/prototype.js"> </script> <script type="text/javascript" src="/javascripts/window.js"> </script> <link href="/stylesheets/themes/default.css" rel="stylesheet" type="text/css"/> <!-- Add this to have a specific theme--> <link href="themes/nuncio.css" rel="stylesheet" type="text/css"/>
To create a window, you just have to instanciate a Window object with some optional parameters, set innerHTML of the window main content and call show() or showCenter() function. Check out the samples tab with more sample codes。
win = new Window({className: "nuncio", title: "demo3", width:200, height:150, destroyOnClose: true, recenterAuto:false}); win.getContent().update("<h1>Hello world !!</h1>"); win.showCenter();
