# 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);

    });
    </script>
