Limiting Text Entry to One Character

Hi All, I'm working on a crossword puzzle and want to restrict the text entry fields to one character. I'm sure this can be done in JavaScript, but that is a skill I am still working on acquirin...

Hi!

From your code, I asked the programmer on the team I work in and we came up with this code and it works.

var elements = document.getElementsByTagName("input");

for (var i = 0, element; element = elements[i++];) {

element.setAttribute('maxlength', 1);

element.setAttribute('autocomplete', 'off');
}

    Indeed thats the way to do this without jQuery.

    For anyone copying and reusing Stephanie's code... keep in mind it gets ALL input elements on the page and loops through them in a for loop.

    This actually worked, but now I have a question...

    How to make it so spaces aren't counted as a character?
