    Java script code for Auto tab (form field)

    This script "auto tabs" a form field (and jumps to another field) once the length of the field's value has exceeded a certain length. It works in conjunction with the "maxlength" attribute of HTML, triggered whenever the user's input reaches the maxlength's value.
    Make certain types of form fields more intuitive and convenient to fill out with this script.

    HTML Code:
    function autotab(original,destination){
    if (original.getAttribute&&original.value.length==original.getAttribute("maxlength"))
    <b>Enter your 10-digit phone number:</b>
    <form name="sampleform">
    <input type="text" name="first" size=4 onKeyup="autotab(this, document.sampleform.second)" maxlength=3> <input type="text" name="second" size=4 onKeyup="autotab(this, document.sampleform.third)" maxlength=3> <input type="text" name="third" size=5 maxlength=4>
    Demo is available in the attachment...
