[Javascript] Selecting certain areas of text in a string

[Nick Fitzsimons]

Apologies if this gets posted twice - my webmail is playing up :-(

Assuming your <object> element has the ID "movie" then

var movie = document.getElementById("movie");
movie.src = movie.src.replace(/somevideo.flv/, "othervideo.flv");

should do the trick.

Regards,

Nick.
