在Jquery对话框中加载Google jsapi失败

我试图显示一个图表从谷歌可视化api到一个jQuery对话框，从另一个页面加载内容，但我收到一个javascript错误，说'谷歌没有定义'当尝试加载图表。这个例子有2个简单的页面。承载对话框的"mainpage.htm"和承载动态加载到jQuery对话框中的图表的"chartpage.htm"。这是'mainpage.htm':

    var url = "chartpage.htm";
    $("#chartDlg").load(url).dialog({ modal: true, width: w, height: h, title: 'MyChart', position: 'center' });
    $("#chartDlg").dialog('open');
}
</script>
</head>
<body>
<a href="javascript: openchart();">Show Chart</a>
<div style="display:none" id="chartDlg"></div>
</body>
</html>

这是'chartpage。htm'

作为独立页面打开的chartpage.htm工作完美，只有当加载到Mainpage.htm对话框中时才会失败。

看起来google jsapi根本没有被加载。

任何想法?

可以尝试一下。

在对话框的iframe中加载chartpage.htm(我自己没有尝试过，但值得一试):

<div style="display:none" id="chartDlg"><iframe src="chartpage.htm"></iframe></div>

并将函数更改为:

function openchart() {
w = $(window).width() - 100;
h = $(window).height() - 100;
$("#chartDlg").dialog({ modal: true, width: w, height: h, title: 'MyChart', position: 'center' });
$("#chartDlg").dialog('open');
}

或

添加google javascript到mainpage.htm:

<script type="text/javascript" src="http://www.google.com/jsapi"></script>
