auto tab with exception
<p>I have a form where I primarily input single digit numbers. I want to auto tab to each input field, however, sometimes, there is a need for a two digit number. The two digit number will always start with "1". So I would like to auto tab on all single digit numbers except 1 and if a 1 is entered the auto tab is disabled so that a second digit can be entered. I will manually tab to the next field where auto tab would then resume.</p>

<p>I can find plenty of code for auto tabbing but none with this type of exception. I am new to javascript.</p>
