Store in value in cookie

[kieran82]

I'm new to using cookies. I am using JavaScript for a web project and I'm using cookies and I have 5 links for different movie trailers and I have a trailers.html page with a div with a id="movie" and want to know so that when you click on a Movie trailer link so that it stores a value in a cookie so that you can check on the trailers page which trailer was chosen and display in the div tag

These are the standard cookie-handling functions to create, read, and erase a cookie:

function createCookie(name, value, days) {
	var expires = '',
        date = new Date();
    if (days) {
        date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
        expires = '; expires=' + date.toGMTString();
    }
    document.cookie = name + '=' + value + expires + '; path=/';
}
 
function readCookie(name) {
    var cookies = document.cookie.split(';'),
        length = cookies.length,
        i,
        cookie,
        nameEQ = name + '=';
    for (i = 0; i < length; i += 1) {
        cookie = cookies[i];
        while (cookie.charAt(0) === ' ') {
            cookie = cookie.substring(1, cookie.length);
        }
        if (cookie.indexOf(nameEQ) === 0) {
            return cookie.substring(nameEQ.length, cookie.length);
        }
    }
    return null;
}
 
function eraseCookie(name) {
    createCookie(name, '', -1);
}
