I grabbed a cookie script from the FAQ to remember which colourscheme a user had selected on a site I have. Here is the code:

code:

function pass(scheme) {

                            //find cookie if page has called for previous scheme

	            if (scheme == "previous") {

	                var name = "colscheme";

	                var cookies = document.cookie;

			if (cookies.indexOf(name) != -1){

						var startpos = cookies.indexOf(name)+name.length+1;

						var endpos = cookies.indexOf(";",startpos)-1;

						if (endpos == -2) endpos = cookies.length;

						pass(unescape(cookies.substring(startpos,endpos)));

					}

			  } else {

                               //colourize is a function that actually gets the crayons out and colours in the page

                                if (scheme == "blue") {

	                    colourize("#1db6e5","#007fa5");

	                }

	                if(scheme == "green") {

	                    colourize("#A1CF99","#62ad46");

	                }

	                if(scheme == "pink") {

	                    colourize("#F855B9","#003");

	                }

	                if(scheme == "brown") {

	                    colourize("#A5CFCB","#ca9c5e")

	                }

	                if(scheme == "grey") {

	                    colourize("#aaa","#444")

	                }

                                //remember scheme selected

	                var expire = new Date();

	                expire.setTime(expire.getTime() + 1000 * 60 * 60 * 24 * 365);

	                document.cookie = "colscheme="+scheme+"; expires="+expire.toGMTString()+";";

	            }

	        }

This seems, however, to be having no effect, i.e. it doesn't remember the scheme when I put onload="pass('previous');" in the body tag. Here is a link to the page in action, can anyone explain why it isn't working?

I don't know why it's not working but the best get and set cookie functions that I know of are also the oldest ones around and you can get them here: http://www.webreference.com/javascript/960701/part01.html
