Question

Is it possible to get a window popup with always 400px wide, but dynamic height depending on the content in the popup window?

I have seen this but not sure how to apply it to popup windows

Adjust width height of iframe to fit with content in it

Solved

$(document).ready(function() {

  // For IE
  var h = $('#page').outerHeight();
  var newH = h + 20;
  window.resizeBy(0, newH - $(window).height());

  // Only works in Firefox/Safari
  $('img').load(function() {
    var h = $('#page').outerHeight();
    var newH = h + 20;
    window.resizeBy(0, newH - $(window).height());
  });
});
