    autoTab with alertbox and choices?!

    I have found this autoTab script on the net:
    Code JavaScript:
    var isNN = (navigator.appName.indexOf("Netscape")!=-1);
    function autoTab(input,len, e) {
    var keyCode = (isNN) ? e.which : e.keyCode; 
    var filter = (isNN) ? [0,8,9] : [0,8,9,16,17,18,37,38,39,40,46];
    if(input.value.length >= len && !containsElement(filter,keyCode)) {
    input.value = input.value.slice(0, len);
    input.form[(getIndex(input)+1) % input.form.length].focus();
    }
    function containsElement(arr, ele) {
    var found = false, index = 0;
    while(!found && index < arr.length)
    if(arr[index] == ele)
    found = true;
    else
    index++;
    return found;
    }
    function getIndex(input) {
    var index = -1, i = 0, found = false;
    while (i < input.form.length && index == -1)
    if (input.form[i] == input)index = i;
    else i++;
    return index;
    }
    return true;
    }

    And called like this:
    Code HTML4Strict:
    <input onKeyUp="return autoTab(this, 1, event);" size="2" maxlength="2">

    Now what I want is if you type "1" in the field an aleretbox popup with 2 choices... first choice is to accept that the field should be only "1" and the second choice is to be able to change the filed 2 a 2 digit field where you can type ex. "13"...

    I got this to envoke the alertbox:
    Code JavaScript:
    if(input.value == 1) {
    alert("I only want it to be 1");
    }

    But I dont know how to make choices within the alertbox and if choice 2 is selected alter the field to a 2 digit field...

    Please help and thanks in advance...

    Here's some info on the alert, confirm, and prompt boxes that should be of some help.
