Question

I am storing a cookie on one page, with inputs in a form with this function:

<script type="text/javascript">
function WriteCookie()
{
   emailValue = escape(document.form.01_email.value) + ";";
   userIDValue = escape(document.form.01_userID.value) + ";";

   document.cookie="email=" + emailValue;
   document.cookie="userID=" + userIDValue;
}
</script>

<form name="form">
 <input type="email" class="form-textbox validate[required, Email]" id="input_10" name="01_email" size="26" value="[e-mail]" />
 <input type="hidden" id="simple_spc" name="01_userId" value="1234" />
</form>

I get redirect to another page once a user submits the form, and I retrieve the cookie with this code but i need to have it find the email and userID in the cookie and insert it in the value of the inputs on this new page:

<script type="text/javascript">
    function ReadCookie()
    {
       var allcookies = document.cookie;
       alert("All Cookies : " + allcookies );

       // Get all the cookies pairs in an array
       cookiearray  = allcookies.split(';');

       // Now take key value pair out of this array
       for(var i=0; i<cookiearray.length; i++){
          name = cookiearray[i].split('=')[1];
          value = cookiearray[i].split('=')[2];
          alert("Email is : " + name + " and UserID is : " + value);
       }
    }
    </script>


    <form name="form">
     <input type="email" class="form-textbox" id="input_10" name="02_email" size="26" value="" />
     <input type="hidden" id="simple_spc" name="02_userId" value="" />
    </form>

I know a user will most likely have multiple cookies, so finding only the email and userID i’m having trouble with.

Answer 1

Try this to read your cookies.

function ReadCookie(){
    var key, value, i;
    var cookieArray  = document.cookie.split(';');

    for (i = 0; i < cookieArray.length; i++){
        key = cookieArray[i].substr(0, cookieArray[i].indexOf("="));
        value = cookieArray[i].substr(cookieArray[i].indexOf("=")+1);

        if (key == 'email'){
            alert('Email is ' + value);
        }

        if (key == 'userID'){
            alert('userID is ' + value);
        }
    }
}
