Ticket #6199: jquery-1.4.2-ie8.js

---

File jquery-1.4.2-ie8.js, 0.9 KB (added by fidian, September 16, 2010 05:31PM UTC)

Plugin to fix behavior in IE8.

/**
 * IE8 sets an offsetWidth and offsetHeight on elements even if they are
 * display: none, but only if there is a visible element before the one
 * you are checking.
 *
 * The "bug" in jQuery (not really jQuery's fault) is reported here:
 * http://dev.jquery.com/ticket/6199
 *
 * Solutions:
 *   Wrap everything in another element if you want to check if it is visible
 *   You can tweak the previous element to make it work (css or text)
 *   You can add an empty comment before the element
 *
 * This plugin uses the last option.
