问题描述

是否可以通过编程方式访问先前记录的 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

如果不自己包装 window.console,我不相信这是可能的.查看源代码,似乎当调用 Firebug 的 console 方法(在主文档中运行,因此没有特殊权限)时,它会在主文档中留下一些对象,然后引发一个自定义事件.在特权插件域中运行的 Firebug 侦听器拾取事件,吞噬文档中剩余的对象并将适当的内容添加到控制台面板,控制台面板是浏览器 chrome 的一部分,因此无法访问在主程序中运行的 JavaScript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.

我可能对这方面的细节有误,因为我只是粗略地查看了 Firebug 源代码,并且很少进行 Firefox 插件开发,但我认为这大体上是正确的.

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.
