if you don't care about a js error you can even just end the script block and start again [assuming, of course, that we are actually _inside_ a script block and not a href or something similar] like so: FOO = '</script><script>alert("extra script blocks are cool.")</script><script>//' sure, you'll get one js error, but it doesn't really matter, as your code will still run.
Hey, you're right. I had a suspicion that this might work, and indeed it does. I wasn't 100% sure, as browsers' parsing algorithms are so incredibly complex, that the obvious may not work. I think when I first came across this situation in an application, most HTML special characters were actually encoded, except for apostrophes, which were backslashed. Anyway, I'll try to post a more difficult one next week. thanks, tim ------------------------------------------------------------------------------ This List Sponsored by: Cenzic Concerned about Web Application Security?
