# YUI Library Examples: Cookie Utility (beta): Simple Cookie Example

# Cookie Utility (beta): 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.

### Note:

Keep an eye on the Logger console at right to view the log messages associated with this example.

## Simple Cookie Example

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 = YAHOO.util.Cookie.get("example");

This value is output into the Logger. Next, the cooke is set to a random value:

var newValue = "yui" + Math.round(Math.random() * Math.PI); YAHOO.util.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 if you close the browser.
