Inject javascript into a javascript function

Question

I\'ve got a weird question in that I need to inject some javascript into another javascript function. I am using a framework which is locked so I can not change the existing fun

Answer 1

I can not change the doSomething function... Instead I need to somehow inject a few lines of code into the end of the doSomething code

Injecting a few lines into the end of the doSomething code sounds like changing the doSomething function, to me. I think, unfortunately, that you’re screwed.

(I’m a bit hazy on all this, but I think functions are how people who worry about such things implement information hiding in JavaScript, precisely because you can’t access their scope from outside them.)
