Re: Wierd use of "new function() {}"

Show all headers | View raw

In case anyone wants to see the actual code, here it is:

//
// This code is supposed to initialize a slideshow over a
// particular image gallery.
//
function startShow(obj) {

  var elem = tag("li", obj);    // Locate elements by tag
  var gallery = id("gallery");  // Locate tag by ID

  for (var i = 0; i < elem.length; i++) new function() {
    var cur = elem[i];
    setTimeout(function() {
        showImage(cur);
        setTimeout(function() {
           fadeOut(gallery, 0, 10);
         }, 3500);
    }, i * 5000);
  }
  setTimeout(hideOverlay, 5000 * elem.length);
  showOverlay();
}

I was just confused about the use of the "new function() {}" as
seen above.  Hopefully someone can explain that to me.
Thanks!
