change style sheets

screamer2k · #1 (**permalink**) Aug 6th, 2004, 10:01

hi ive been given this javascript code to be put into an html document which enables me to change between external stylesheets. i would also like to change between the original html page too. If possible an internal javascript code.
Heres the Xhtml code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html>
<head>

<link type="text/css" rel="stylesheet" href="Q2sheet1.css"/>
<title>Question 2</title>
<meta http-equiv="content-type" content="text/html; charset=utf-8 code"/>
</head>
<body>
<h1>styles.html</h1>
<h2>Harry Potter...</h2>

<big>H</big>e-Who-Must-Not-Be-Named has been named.
Ralph Fiennes, who played memorable evil guys in "Red Dragon" and "Schindler's List," has signed on to portray the wicked warlock Voldemort in the next "Harry Potter" movie, Warner Bros. announced Wednesday. Voldemort is so bad that the magical characters in author J.K.
Rowling's stories do their best not to speak his name aloud. XP</p>
</body>
</html>

And heres the Javascript code ive been given to crack !:

function changeStyleSheet(url) {
//find <link> tag with attribute rel="stylesheet"
var links = document.getElementsByTagName('link') ;
for (var i=0; i<links.length; i++) {
if (links[i].getAttribute('rel') == 'stylesheet') {
var theLink = links[i] ;
break;
}
}
//If we found a stylesheet <link> then change it !
if (theLink) {
//replace its href attribute with the new URL
theLink.setAttribute('href', url) ;
}
}

PLEASE IF ANYONE CAN HELP ILL APPRECIATE IT.

please explain your question further... you want the chosen CSS to persist accross pages?

no, i just want the page to have three buttons using the javascript code given.. so that one page can switch between two stylesheets i have and one original html page. All from the main page.
thanks!
