查阅文件
原标题:Accessing document s javascript variable from firefox extension

能否让>延伸(托olbar)查阅变数文件? 详细解释如下。

装载文件:

<script type="text/javascript">
var variableForExtension =  something ;
</script>

延长:

var win = window.top.getBrowser().selectedBrowser.contentWindow;
alert(win.variableForExtension); // undefined

这是首当其冲的尝试,而且由于安全机制(XPCNativeWrapper)而无法进入。 i 读到如何使用(从延伸到文件的倾听和发送活动),但无uck。 然而,这样做太困难。 因此,在挖掘深度之前(事件方法像走路一样合理),我想知道这是否可行?

感谢

不是如此困难的:

延长:

var jso=window.content.document.defaultView.wrappedJSObject;

现在,你可以查阅从延长开始的网页上的任何功能或全球变量:

alert(jso.pagevar);

jso.pagefunction("hey");
