Is it possible to open empty html popup with JS in it?

So we can do:

<html>
<head>
 <title>JavaScript Popup Example 3</title>
</head>

<script type="text/javascript">
function exitpop()
{
    my_window = window.open("", "mywindow1", "status=1,width=350,height=150");
    //my_window.document.write('somehow add JS'); 
    my_window.document.write('<h1>Popup Test!</h1><br/>'); 
    my_window.document.write('J_\alpha(x) = \sum_{m=0}^\infty \frac{(-1)^m}{m! \, \Gamma(m + \alpha + 1)}{\left({\frac{x}{2}}\right)}^{2 m + \alpha} ');
}
</script>

<body onunload="javascript: exitpop()" >
<h1>JavaScript Popup Example 4</h1>
</body>
</html>

but how to for example add to header of that html page with something like <script type="text/javascript" src="path-to-MathJax/MathJax.js"></script> to enable MathML and tex formulas rendering?

You can consider using an iframe, you can set its head and body altogether, and you can put it in the window.

Yep, you just need to concatenate the script tags, like so: jsfiddle demo

The money-shot code sample is:

jswin = window.open("", "jswin", "width=350,height=150");
jswin.document.write("Here's your popup!");
jswin.document.write('<scr'+'ipt>alert("Here\'s your alert()!");</scr'+'ipt>');

Use javascript to create a node named script, and sets it's attributes with javascript. Then append the node to document.head. 

<html>
<head>
 <title>JavaScript Popup Example 3</title>
</head>

<script type="text/javascript">
function exitpop()
{
    var my_window = window.open("", "mywindow1", "status=1,width=350,height=150");


    var head = my_window.document.getElementsByTagName("head").item(0);
    alert(head.innerHTML);
      var script = my_window.document.createElement ("script");  
      script.src = "a.js";  
      head.appendChild (script);
    alert(head.innerHTML);
}
</script>

<body onunload="javascript: exitpop()" >
<h1>JavaScript Popup Example 4</h1>
</body>
</html>
