You might also consider the StringContentValid tag in the JSTags taglib from Java Web Parts:
http://javawebparts.sourceforge.net Specifically: http://javawebparts.sourceforge.net/javadocs/javawebparts/taglib/jstags/StringContentValidTag.html I *think* you can do: <input type="text" onKeyUp="return JWPStringContentValid(this.value, 'abc123', JWPSCV_FROMLIST);"> Replace 'abc123' with only those characters you want to be allowed, and that should do it. If it happens to not work that way, try: <input type="text" onKeyUp="v=this.value;if (!JWPStringContentValid(this.value, 'abc123', JWPSCV_FROMLIST)){this.value=v;}"> Only slightly more effort that way :) Frank -- Frank W.
