/* * Alternate style sheet selector for Internet Explorer * Keith Beidelman 7-Jan-2004 * * Usage: In your HTML, include the following items: * * In the section: * * * * * In the section: * Add links to change the default style sheet of the form: * * * * Where: 'print' and 'default' come from titles of style sheets * included in link tags. The stylesheet URL is in the href of * the link tag. * * Notes: The first listed link will be the default link. * Alternate links can be listed under that. * * The style sheets take effect for all pages on the site * which use this package. The links to change the style * only need to appear on a single page. They take effect * for all pages. The SCRIPT and the LINKs must be included * in all the pages. * * Once a browser selects a style, it is remembered for that * browser for 1 year using cookies. If the user disables * cookies, the style change will only stick for the page * where the change link was pressed. No error telling the * user to enable cookies is ever displayed. */ var curstyle; function getStyle () { var i, e, a; e = document.getElementsByTagName ("link"); for (i=0; a = e[i]; i++) if (a.getAttribute ("rel").indexOf ("style") != -1 && a.getAttribute ("title") && !a.disabled) return a.getAttribute ("title"); return null; } function defaultStyle () { var i, e, a; e = document.getElementsByTagName ("link"); for (i=0; a = e[i]; i++) if (a.getAttribute ("rel").indexOf ("style") != -1 && a.getAttribute ("rel").indexOf ("alt") == -1 && a.getAttribute ("title")) return a.getAttribute ("title"); return null; } function makeCookie (name, value, days) { var expires, date; if (days) { date = new Date (); date.setTime (date.getTime () + days * 24 * 60 * 60 * 1000); expires = "; expires=" + date.toGMTString (); } else expires = ""; document.cookie = name + "=" + value + expires + "; path=/"; } function readCookie (name) { var i, c, namevar, va; namevar = name + "="; vc = document.cookie.split (';'); for (i = 0; i < vc.length; i++) { for (c = vc[i]; c.charAt (0) == ' '; c = c.substring (1, c.length)); if (c.indexOf (namevar) == 0) return c.substring (namevar.length, c.length); } return null; } function setStyle (title) { var i, e, a, main; e = document.getElementsByTagName ("link"); for (i=0; a = e[i]; i++) if (a.getAttribute ("rel").indexOf ("style") != -1 && a.getAttribute ("title")) a.disabled = (a.getAttribute ("title") != title); makeCookie ("style", title, 365); curstyle = title; return false; } function useCookieStyle () { var cookie, style; cookie = readCookie ("style"); title = cookie ? cookie : defaultStyle (); setStyle (title); return title; } window.onload = function (e) { useCookieStyle (); } useCookieStyle (); function rotStyle (a, b) { if (curstyle == a) return setStyle (b); else return setStyle (a); }
