Example: Simple Cookie Example

This example shows basic usage of the YUI Cookie utility. The example checks the value of a cookie and then sets it to a new value.









Description



This example begins by getting the value of a cookie named "example". If this is the first time you've run
the example, the value should be null:


var currentValue = Y.Cookie.get("example");




This value is shown in the browser console. Next, the cookie is set to a random value:



var newValue = "yui" + Math.round(Math.random() * Math.PI);
Y.Cookie.set("example", newValue);




When you reload the page, the value of the cookie should be the one that was just set.



Note: this example uses session cookies, so the value will be lost when you close the browser.

<pre id="results"></pre>

<script>
YUI().use('node', 'cookie', function (Y) {

    var pre = Y.one('#results'),
        log = function(str) {
            pre.append(str + '<br>\n');
        };

    var currentValue = Y.Cookie.get("example");
    log("Cookie's current value is '" + currentValue + "'");

    var newValue = "yui" + Math.round(Math.random() * Math.PI * 1000);
    log("Setting cookie's value to '" + newValue + "'");
    Y.Cookie.set("example", newValue);
