XHTML+CSS的静态页面实现多风格选择的方法-(0)

1. styleswitcher.js

function getActiveStyleSheet() {
  var i, a;
  for(i=0; (a = document.getElementsByTagName(“link”)[i]); i++) {
if(a.getAttribute(“rel”).indexOf(“style”) != -1 && a.getAttribute(“title”) && !a.disabled) return a.getAttribute(“title”);
  }
  return null;
}

function getPreferredStyleSheet() {
  var i, a;
  for(i=0; (a = document.getElementsByTagName(“link”)[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 createCookie(name,value,days) {
  if (days) {
var date = new Date();
date.setTime(date.getTime()+(days*24*60*60*1000));
var expires = “; expires=”+date.toGMTString();
  }
  else expires = “”;
  document.cookie = name+”=”+value+expires+”; path=/”;
}

function readCookie(name) {
  var nameEQ = name + “=”;
  var ca = document.cookie.split(‘;’);
  for(var i=0;i < ca.length;i++) {
var c = ca[i];
while (c.charAt(0)==’ ‘) c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
  }
  return null;
}

window.onload = function(e) {
  var cookie = readCookie(“style”);
  var title = cookie ? cookie : getPreferredStyleSheet();
  setActiveStyleSheet(title);
}

window.onunload = function(e) {
var title = getActiveStyleSheet();
createCookie(“style”, title, 365);
}

var cookie = readCookie(“style”);
var title = cookie ? cookie : getPreferredStyleSheet();
setActiveStyleSheet(title);
