Was wanting to know how to check using jquery if a input contains a number higher then 99
Simply use this:
if ($("input.INPUTNAME").val() > 99) { //above 99 code }
You may want to have an else command, if the input is below 99.
if ($("input.INPUTNAME").val() > 99) { //above 99 code. } else{ //Not above 99 code. }
