您能以编程方式访问Firebug控制台输出吗？ [英] Can you programmatically access the Firebug console output?

问题描述

是否可以通过编程方式访问以前记录的Firebug输出？

Is it possible to access the previously-logged output of Firebug programmatically?

例如：

console.log('a');
console.log('b');
console.log('c');

for (var i = 0; i < console.output.length; ++i) {
    alert(console.output[i]);  // "a", "b", "c"
}

推荐答案

没有自己包装 window.console ，我不相信这是可能的。看看源代码，似乎当调用Firebug的控制台方法（在主文档中运行，因此没有特殊权限）时，它会留下一些对象。主文档然后引发自定义事件。在特权插件中运行的Firebug侦听器拾取事件，吞噬文档中剩余的对象并向控制台面板添加适当的内容，控制台面板是浏览器镶边的一部分，因此在主要运行的JavaScript中无法访问窗口。

Without wrapping window.console yourself, I don't believe this is possible. Looking at the source, it seems that when a Firebug's console method (running within the main document and therefore having no special privileges) is called, it leaves some objects lying around in the main document and then raises a custom event. A Firebug listener running in privileged-plug-in-land picks up the event, gobbles up the objects left in the document and adds appropriate things to the console panel, which is part of the browser chrome and therefore inaccessible to JavaScript running in the main window.

我可能错了这个细节，因为我只是粗略地看一下Firebug源并完成了很少的Firefox插件开发，但是我认为这是大致正确的。

I could be wrong about the details of this because I've only taken a cursory look at the Firebug source and done very little Firefox plug-in development, but I think this is broadly correct.
