JQuery and a lot of other JS code would break in pretty obvious ways if any major browser did this. http://code.jquery.com/jquery-1.6.2.js contains rscript = /<script\b[^<]*(?:(?!<\/script>)<[^<]*)*<\/script>/gi, and the "i" flag handling delegates to toUpperCase per 15.10.2.8 so would never actually match "<SCRIPT", instead matching only the version with a dotted upper-case I. I seem to remember that some version of Rhino did this though, delegating both toUpperCase and toLocaleUpperCase to java.lang.String.toUpperCase() which uses the default locale. _______________________________________________ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
