Code Sign Javascript to use 'new ActiveXObject()' / 'GetObject()'

I've got a javascript file that uses

excel = GetObject("", "Excel.Applica开发者_JAVA技巧tion"); 

to hook a current running instance of excel, however it requires me to drop my security settings super low. How do I go about code-signing a javascript file to at least cause a security prompt instead of just failing? Google-ing keeps getting me results for signing custom activex controls, .dlls, and .exes but all I need is the built-in function approved.

On a related note

"The GetObject function is not supported in Internet Explorer 9 standards mode or later."

What is the proper method for accessing a currently running application in IE9 then?

There is no way to do that; there's no "code signing" mechanism for JavaScript.
