Hi All:

    My onkeyup clause in my <input> element below works correctly under 
Chrome 54.0.2840.99

    That is, when I receive a <return> character, I sense it, 'blur' the 
field, and then go thru the validation process by executing my validate() 
function. Tabbing also works correctly.

    However, when testing under Firefox 50.1.0, the onkeyup clause fails to 
execute my chkforret function.  Apparently, I need to pass the 'event' as 
argument to the chkforret function instead of 'this' ??

My essential question is then:

    Does onkeyup 'work' in Firefox ?

     If so, what changes should I make to get it to work for me in the code 
below so that Chrome and FF are both satisfied ?

Thank you.

*** my currect js code for inputting a 3-char text field ***
<input type="text"; onkeyup="chkforret(this);(gotret)?this.blur():false;" 
onblur="setBlurColor(this);validate(this);" id="ulotno" name="lotno" 
size="4" maxlength="3" value="">
