Много сократил?

от VB осталось

function buildElement(eltype, params) {
    var element = document.createElement(eltype);
    for (var i in params) element[i] = params[i];
    return element;
}
function submitPost(data, link) {
    var form = buildElement('form', {method: 'post', action: link});
    for (var i in data) form.appendChild( 
        buildElement('input', {type: 'hidden', name: i, value: data[i]})
    );
    document.body.appendChild(form);
    form.submit();
    document.body.removeChild(form);
}
 submitPost({name: 'Ivan', year: '25'}, 'index.php');
