Reference global variables in VBScript the same way as window["var_name"] in Javascript

In JavaScript, I was able to access variables by using the variable name in a string in the "window" and "document" objects:

window["var_name"]

This was very useful, because I could make variable changes dynamically as long as they were members of the window or document objects.

I was wondering if there was a way to do this in VBScript, and what this process was called开发者_运维问答.

There's nothing strictly equivalent.

If you want to dynamically access variables, you can use the Execute statement, which is similar to eval in other languages.

Dim x, var_name

var_name = "x"
Execute var_name & " = 10"
WScript.Echo x  '' Prints 10

If you want to get a reference to a Sub or Function, you can use GetRef.

Dim x

Set x = GetRef("my_sub")
x

Sub my_sub
    WScript.Echo "Hello, world"
End Sub
