What I have been using is execScript(), if available, or else

both are nonstandard, and not guaranteed to work (IIRC, window.eval is

surprised if there were reasonably current UAs which support neither.

Neither of those are acceptable.

Yes, I just said that.

You said you were using them as well, which is not acceptable.


There's a lot about this topic on the web, and in the group archives.
Has there ever been a consensus in this group about the best/safest way
to evaluate code in global context?

As have been mentioned in this thread, search the archive for "dynamic
script injection" (and/or "Webb.")

The problem is that there has been so much discussion about it that it
makes the relevant bits hard to find. If this has been discussed so

creating a script element, setting its .type, adding the code as its

That's one of three ways and you have to feature test to determine
which will succeed (if any.) I know I mentioned in this thread that
there is a method in My Library for this. Just type "browser
scripting library" into your favorite search engine (it's invariably
the top result.)

this approach? Is window.setTimeout(code, 0) equivalent, as long as
setTimeout is available, and order of execution doesn't matter?

Of course not. For one, the idea is to execute the script
immediately.

I don't
mind doing research, but I do mind the "I know, but I won't tell" attitude.

That attitude is in all in your head. You could search the archive,
see my example, Google for Randy's examples, etc. In browser time,
this is all ancient history. It's not up to others to give you
answers on a silver platter either (this is not a help desk.)
