javascript - How to reload script tag -

i'm dynamically changing script tag's src attribute using javascript.

problem is, i'd "undo" previous javascript before re-executing it. way this?

thanks,

g3

i can describe method used accomplish partial undo in project. ugly, might useful. first, may need refactor script work within iframe, and/or wrap in with statement give easy access objects in parent (don't think of with(opener); you'll want more precise with({someobject: opener.someobject}).

when script runs, can utilize iframe's global scope , dom freely. then, instead of reloading <script> tag, overwrite whole iframe, reset script did within iframe.
