页面上调用的方式
<input type="image" src="images/gy45.gif" onClick  ="javascript:bookmark(document.title, document.URL);return false" />


实现收藏页面的js
function bookmark(title, url) {
  if (document.all)
    window.external.AddFavorite(url, title);
  else if (window.sidebar)
    window.sidebar.addPanel(title, url, "")
}
