获取所有的Javascript变量？ [英] Get all Javascript Variables?

问题描述

有没有办法让JavaScript检测所有分配的变量？例如，如果一个js文件创建了一堆vars（全局作用域），后续文件可以获得所有vars而不知道它们是什么名称以及哪些可能存在？

在此先感谢：）

编辑，问题第2部分：

如何获取这些变量？这是我的尝试：

这是我结束了，根据评论意见：

 for（var name in this）{
 variables [name] = name; 
 variables [name] = this [name] 
} 
  

解决方案Flanagan的JavaScript - 权威指南在第653页给出了以下内容：

  var variables =
 
 for（var name in this）
 variables + = name +\\\
; 
  

Is there a way for javascript to detect all assigned variables? For example, if one js file creates a bunch of vars (globally scoped), can a subsequent file get all the vars without knowing what they're named and which might exist?

Thanks in advance :)

EDIT, Question Part 2:

How do I get the values of these variables? Here is what I have attempted:

This is what I ended up with, as per comment suggestions:

for (var name in this) {
    variables[name] = name;
    variables[name]=this[name]
}

解决方案

Flanagan's "JavaScript - The Definitive Guide" gives the following on page 653:

var variables = ""
for (var name in this)
    variables += name + "\n";
