I want to change the used CSS File (<link href="..." />
) dynamically using only javascript and to save changes in cookies.
This is a jQuery version that does what I want (ref), but how can I do this in javascript?
if($.cookie("css")) {
$("link").attr("href",$.cookie("css"));
}
$(document).ready(function() {
$("#nav li a").click(function() {
$("link").attr("href",$(this).attr('rel'));
$.cookie("css",$(this).attr('rel'), {expires: 365, path: '/'});
return false;
});
});
Thank you in advance.
maybe this could help you..
(function() {
var e = document.createElement('link');
e.href = document.location.protocol + '//example.com/file.css';
e.type = 'text/css';
e.rel = 'stylesheet';
e.media = 'screen';
document.getElementsByTagName('head')[0].appendChild(e);
}());
Edit, full JavaScript without jQuery
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 var 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;
}
function eraseCookie(name) {
createCookie(name,"",-1);
}
document.addEventListener('DOMContentLoaded',function(){
if(readCookie('css')){
var e = document.getElementById('test-css'); // <link href="..." id="test-css"/>
e.href = readCookie('css');
}
var element = document.getElementById('change-css'); // <a herf="#" id="change-css" rel="file.css">Click Here</a>
element.addEventListener('click', function (event) {
var e = document.getElementById('test-css');
e.href = this.rel;
if(readCookie('css')){
eraseCookie('css');
}
createCookie('css',this.rel,365);
event.preventDefault();
}, false);
})
