I would like to present to the user several input
text box that allows them to type a string of letters or characters that stores one letter into each box in a \'sp
As @Mr.Alien said, setting MaxLength property will safeguard the text box in having more than 1 character of text. Additionally, You should select the text in the text box while it is getting a focus. It will simplify the process if user starts from the first text box again.
$("input").keyup(function() {
var input_flds = $(this).next("input");
input_flds.select().focus();
});
DEMO It is a modified copy of @Mr.Alien demo
Update:
Implementing the above concept in a selected text box, [Concept: Set a class for the text boxes which you want to apply the need]
$("input").keyup(function() {
var input_flds = $(this).nextAll(".test:first");
input_flds.select().focus();
});
//where .test will be your class on the selected text boxes.
