如何在屏幕中央打开一个特定的窗口

在学习中，无意看到了如下代码，觉得很不错，收藏了。

source：How do I open a new window of a certain size?

   1:  <html>
   2:  <head>
   3:  <script>
   4:  <!--
   5:  function wopen(url, name, w, h)
   6:  {
   7:    // Fudge factors for window decoration space.
   8:    // In my tests these work well on all platforms & browsers.
   9:    w += 32;
  10:    h += 96;
  11:    wleft = (screen.width - w) / 2;
  12:    wtop = (screen.height - h) / 2;
  13:    // IE5 and other old browsers might allow a window that is
  14:    // partially offscreen or wider than the screen. Fix that.
  15:    // (Newer browsers fix this for us, but let's be thorough.)
  16:    if (wleft < 0) {
  17:      w = screen.width;
  18:      wleft = 0;
  19:    }
  20:    if (wtop < 0) {
  21:      h = screen.height;
  22:      wtop = 0;
  23:    }
  24:    var win = window.open(url,
  25:      name,
  26:      'width=' + w + ', height=' + h + ', ' +
  27:      'left=' + wleft + ', top=' + wtop + ', ' +
  28:      'location=no, menubar=no, ' +
  29:      'status=no, toolbar=no, scrollbars=no, resizable=no');
  30:    // Just in case width and height are ignored
  31:    win.resizeTo(w, h);
  32:    // Just in case left and top are ignored
  33:    win.moveTo(wleft, wtop);
  34:    win.focus();
  35:  }
  36:  // -->
  37:  </script>
  38:  </head>
  39:  <body>
  40:  <a href="page.html" target="popup"
  41:    onClick="wopen('page.html', 'popup', 300, 200); return false;">
  42:  Click here to open the page in a new window. </a>
  43:  </body>
  44:  </html>
