Answer 1

<a HREF="javascript:window.close()">remove</a>

OR

var my_first_window = window.open('test/test.html');
var my_second_window = window.open('test/test1.html');

window.onunload = function() {
    if(!my_first_window.closed)
        my_first_window.close();
    if(!my_second_window.closed)
        my_second_window.close();
}

Answer 2

Heres an example of what your trying to do... http://jsfiddle.net/KjBj3/7/

var win = window.open("", "win","width=200,height=100");
win.document.write('<a href="#" id="close" onclick="window.close();">This is myWindow! Click to close</a>');
win.focus();
win.opener.document.write('<p>This is the source window!</p>');
