Dear Forum, I'm implementing a style switcher to set the active css - changing graphics.
for it to work it requires in the html head refs to the css files:
the first time opening the page, it uses the first given stylesheet - canvas, but after the style is changed, when opening subpages or reopening the site (especially noticable on safari) http://www.delightwebdesign.co.uk/ it loads the (first) canvas sheet and then overwrites the graphics etc with the active stylesheet. The javascript is:Code:<link rel="stylesheet" type="text/css" media="screen" href="/css/canvas.css " title="canvas"> <link rel="stylesheet" type="text/css" media="all" href="/css/corporate.css " title="corporate"> <link rel="stylesheet" type="text/css" media="all" href="/css/earth.css " title="earth"> <link rel="stylesheet" type="text/css" media="all" href="/css/creative.css " title="creative"> <link rel="stylesheet" type="text/css" media="all" href="/css/space-and-stars.css " title="space-and-stars"> <link rel="stylesheet" type="text/css" media="all" href="/css/under-the-sea.css " title="under-the-sea"> <link rel="stylesheet" type="text/css" media="all" href="/css/classical.css " title="classical">
is there a way to update the code used here - either html or javascript to avoid this, e.g. to delay the html css refs bringing in the first canvas graphics or to run the javascript before it happens?Code:function setActiveStyleSheet(title) { var i, a, main; for(i=0; (a = document.getElementsByTagName("link")[i]); i++) { if(a.getAttribute("rel").indexOf("style") != -1 && a.getAttribute("title")) { a.disabled = true; if(a.getAttribute("title") == title) a.disabled = false; } } } 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);
help much appreciated,
Will
