How to get a cookie value for input field?

Question

I have a form and I have set cookies to the input fields. I can find the cookies in resources when I go to inspect element. The code is confidential so I can't show how I set my cookies. But I am sure that I can find the selected input fields in resources->cookie.

The same form appears in all the pages. When I redirect from one page to other page the form fields which I selected must appear in all the pages.

I used the below code for getting the cookie value

<script type="text/javascript">
    $(document).ready(function() {
        if(input1 = getCookie("input1 "))
            document.myform.input1.value = input1 ;
    });
</script>

but I am getting error as Uncaught ReferenceError: getCookie is not defined

Can anyone suggest what would be the reason for this error? and how do I get the get cookie value to the input field?

Usually you should google it how to set cookie, not sure if you declare the function as something like getCookie?

<script type="text/javascript">
    function setCookie(key, value) {
        var expires = new Date();
        expires.setTime(expires.getTime() + (1 * 24 * 60 * 60 * 1000));
        document.cookie = key + '=' + value + ';expires=' + expires.toUTCString();
    }

    function getCookie(key) {
        var keyValue = document.cookie.match('(^|;) ?' + key + '=([^;]*)(;|$)');
        return keyValue ? keyValue[2] : null;
    }

    $(document).ready(function() {
        setCookie("input1",'1');
        alert(getCookie("input1"));
        document.myform.input1.value = getCookie("input1");
    });

</script>

from where do you get 'key' here in the function getCookie(key) — rjtha rjtha, Oct 09 '14 at 07:05
Actually key is what the parameter in that whatever created cookie name should come, I edited not if you see the edited ans you may know how it works. If you try the above code it will work. — Vignesh Pichamani, Oct 09 '14 at 07:28
