Sending POST through function in javascript

Question

I'm using the following code to send POST request if validation passes. But it doesn't. Can someone show me a wway to make it work.

<script type="text/javascript">

    function go()
    {
    var username = document.form.name.value;
    var pwd = document.form.pwd.value;
    if (username == '') {
      var oldHTML = document.getElementById('myAnchor').innerHTML="Please fill out username.";
    var newHTML = "<span style='color:red'>" + oldHTML + "</span>";
    document.getElementById('myAnchor').innerHTML = newHTML;
    }
    if (pwd == '') {
      var oldHTML = document.getElementById('myAnchor2').innerHTML="Please fill out password.";
    var newHTML = "<span style='color:red'>" + oldHTML + "</span>";
    document.getElementById('myAnchor2').innerHTML = newHTML;
    }
      else {
       document.form.method="POST";
       document.form.action = "data.php";
    }
    </script>

Everything looks correct, you just need to actually submit the form. Add the following line into your else block like this:

else {
    document.form.method="POST";
    document.form.action = "data.php";
    //submit the form -- new line is below
    document.form.submit();
    }
