查看在Chrome中传递给JavaScript函数的参数 [英] view parameters passed to JavaScript function in Chrome

问题描述

我在Chrome开发人员工具中使用时间线来帮助编写用户脚本。时间线显示哪些函数被调用，但不是实际传递给参数的值：

有没有办法查看运行的实际功能，包括其值？我正在寻找任何解决方案，可以帮助我做到这一点，甚至在Chrome之外。

打开 Sources 选项卡在 DevTools ，选择左边的 Snippets 选项卡，右键单击并选择新建，在中间窗口放置函数文本，从定义函数返回 arguments ，在中间窗口选择函数文本，右键单击并选择添加到监视。在> Watch Expressions 右边的窗口中，应该在左边列出所选择的命名函数，然后是如何调用函数，例如 fn（abc，def ）后跟：参数[n] 指示并列出参数传递给函数where n 是参数的数量传递;例如参数[2] 用于 fn（abc，def）

I'm using Timeline in Chrome Developer Tools to help write a userscript. The timeline shows which functions are called, but not what values are actually passed to the parameters:

Is there a way to view the actual function that was run, including its values? I'm looking for any solution that will help me do this, even outside of Chrome.

解决方案

Open Sources tab at DevTools, select Snippets tab at left, right-click and select New, place text of function in middle window, return arguments from defined function, select text of function in middle window, right-click and select Add to Watch . At right window at Watch Expressions selected named function should be listed on left followed by how function is called, e.g., fn("abc", "def") followed by : Arguments[n] indicating and listing arguments passed to function where n is number of arguments passed; e.g., Arguments[2] for fn("abc", "def")
