Answer 1

I've created a function to do this:

function PostDataRedirect(data, dataName, location) {
var form = document.createElement("form");

form.method = "POST";
form.action = location;

if (data.constructor === Array && dataName.constructor === Array) {
    for (var i = 0; i < data.length; i++) {
        var element = document.createElement("input");
        element.type = "hidden";
        element.value = data[i];
        element.name = dataName[i];
        form.appendChild(element);
    }
} else {
    var element1 = document.createElement("input");
    element1.type = "hidden";
    element1.value = data;
    element1.name = dataName;
    form.appendChild(element1);
}

document.body.appendChild(form);

form.submit(); 
}

Usage for question:

PostDataRedirect([ un, pw ], ["un", "pw"], "login.php");
