How to advance to the next form input when the current input has a value?

Question

I am having a form with lots of entries. I would like to change my focus to the next textbox, once I entered the value in the current textbox. and want to continue this proc

Answer 1

This simulates a tab through a form and gives focus to the next input when the enter key is pressed.

window.onkeypress = function(e) {
    if (e.which == 13) {
        e.preventDefault();
        var inputs = document.getElementsByClassName('input');
        for (var i = 0; i < inputs.length; i++) {
        if (document.activeElement.id == inputs[i].id && i+1 < inputs.length ) {
            inputs[i+1].focus();
            break;   
        }
    }
