Why not check if whatever element you're trying to use is available? Maybe do some kind of polling. Ultimately, aren't you trying to detect document readiness? [...] -- kangax

Or perhaps a bookmarklet. Use your imagination, there are a number of cases where a script under your control is injected into a document and you have no control over the source document or when/how your code gets inserted. The ajax/eval method was just an example. Matt Kruse

Last month here was 2169. The jQuery group is being moved away from Groups because of unmanageable spam. The number of readers may be reflected by this. Or perhaps jQuery is becoming so well known and documented that not as many people need help with it. How do you like them apples? :) Or perhaps jQuery popularity is fading. If that's the case, so be it. Perhaps it will be replaced by something different as the most popular scripting library. Doesn't matter to me. Matt Kruse |
