I would like to ask how to return variable ‘get_cookies’ from function ‘save_value’. Then write its value in mouseleave event.

Function ‘get_cookies’ will save change from input. An error is in return i think.

Sorry for my bad English.

Here is code:

<html>
<head>
    <script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
    <script src="jquery.cookie.js" type="text/javascript"></script>
    <script type="text/javascript">
        $(document).ready(function() {
            function save_value(value) {
                var get_cookie = value;
                return get_cookie;
            };

            $('#submit_value').live('click', function() {
                var get_value = $('#get_value').val();
                save_value(get_value);
            });

            $(document).mouseleave(function() {
                var create_cookie = save_value();
                console.log('save: ' + create_cookie);
            });
        });
    </script>
</head>
<body>
    <input type="text" id="get_value" />
    <input type="button" id="submit_value" value="Click" />
    <div></div>
</body>

console log:

save: undefined

Thx for answer.

    the function save_value() is expecting a parameter. Since here

    var create_cookie = save_value();

    you’re not passing a value to the function, it will return undefined, thus the variable create_cookie value is undefined too
