在全局范围内查找JavaScript函数 [英] Finding JavaScript function in the global scope

问题描述

有没有办法在当前活动对象模型中搜索JavaScript属性（例如命名函数）（DOM选项卡上显示的是Firebug，在Chrome Developer Tools中找不到直接的等价物）使用主要浏览器的常用开发工具？

Is there a way to search for a JavaScript attribute (e.g. a named function) in the currently live object model (what Firebug displays on the 'DOM' tab, I couldn't find a direct equivalent in the Chrome Developer Tools) of the currently loaded page, using the common developer tools of the main browsers?

一个例子是我搜索beta，开发人员工具显示我的东西 window.alpha.beta ，这意味着某些脚本文件已经在窗口对象上创建了一个名为alpha的对象，该对象具有属性beta。

An example would be that I search for 'beta' and the developer tools show me something like window.alpha.beta, meaning that some script file has created an object named 'alpha' on the window object, which has an attribute beta.

我明确地不想在所有脚本文件中搜索字符串（例如 Ctrl-Shift-F Chrome开发人员工具）。

I explicitly do not want to search for strings in all script files (e.g. Ctrl-Shift-F in the Chrome Developer Tools).

用例是我想从扩展名/ userscript调用该页面的功能。我知道这个函数是存在的，但是它是使用一个复杂的框架创建的，我不知道页面的对象模型中哪里最终出现。

The use case is that I want to call a function of the page from an extension/userscript. I know the function exists, but it is created using a complex framework and I can't tell where in the page's object model it ends up.

推荐答案

加载 https://github.com/angus-c/waldo ，并从控制台使用它看起来应该做的伎俩。一点点复杂，但也与工具无关。

Loading https://github.com/angus-c/waldo and using it from the console looks like it should do the trick. A little more complex but also tool-agnostic.
