Answer 1

how about:

<p id="new">test<p>
<input id="button" type="submit" name="button" value="enter" />

var clicked = false;

document.getElementById('button').onclick = function() {
  document.getElementById("new").innerHTML = clicked ? "shiva" : "Mijn Naam!";
  clicked = !clicked;
};

Answer 2

switch is a reserved word. You should use some variable name else.

By the way, your code is possible to be compressed as follows:

var switchOn = true;

document.getElementById('button').onclick = function() {
    document.getElementById("new").innerHTML = 
        switchOn ? "shiva" :"Mijn Naam!";
    switchOn = !switchOn;
}
