With the below code, the focus() of the textbox is never achieved on a bad value, so onBlur is always true causing a loop. <input type=text name=filename value="" onBlur="validateFileEntry(this.value, this)"> function validateFileEntry(validString, field) { var isCharValid = true; var i, invalidChar; for (i=0; i<validString.length; i++) { if (validString.charAt(0) == '.') { isCharValid = false; i = validString.length; } if (validateCharacter(validString.charAt(i)) == false) { isCharValid = false; invalidChar = validString.charAt(i); i = validString.length; } } if (i < 1) { return false; } if (isCharValid == false) { if (invalidChar) alert("Invalid filename. Can't contain '" + invalid+ "'."); else alert('Invalid filename.'); if (field) { field.focus(); field.select(); } return false; } return true; } function validateCharacter(character) { if ((character >= 'a' && character <= 'z') || (character >= 'A' && character <= 'Z') || (character >= '0' && character <= '9') || (character =='-') || (character == '.') || (character == '_')) return true; else return false; }

Thanks for the excellent bug report. I'm going to pass it on to the libMocha component. I can't promise it'll be fixed, because it looks like it's on the mozilla 'classic' codebase - current development efforts are being focused on the nglayout/xpfe codebase.

This may very well still exist in the new code; I will try this soon.

Setting all current Open Critical and Major to M3

per leger, assigning QA contacts to all open bugs without QA contacts according to list at http://bugzilla.mozilla.org/describecomponents.cgi?product=Browser

DOM bugs are not my problem.

Tom, Would you see if this is also a 5.0 bug. Then pass it to dprice for libmocha. Thanks, = C =

QA contact re-assigned according to the product areas we're currently working on.

moving off the m3 list.

Moving to DOM Level 0 component. Move to DOM Level 1 if that is more correct.

added to status white board, this is a GFX text field issue

Fixed
