Question

使用setcookie设置的Cookie在Chrome和Firefox中都很好用。使用document.cookie（来自表单）设置的cookie显示为返回并重新进入Chrome中的页面，并且在Firefox中根本不显示。我在这里做错了什么？

的index.php

<?php
$value = "chocolate";
setcookie("anothercookie", $value, time() + (86400 * 30), '/');
?>

<html>
<body>

<form action="action.php" method="GET">
  Name: <input type="text" name="username" /><br /><br />
  Cookie: <input type="text" name="formCookie" /><br /><br />
  <input type="submit" name="submit" value="Submit" />
</form>

<script>
  var myJavascriptVar = document.querySelector('[name="formCookie"]').value;
  document.cookie = "myJavascriptVar = " + myJavascriptVar;
</script>  


</body>
</html>

action.php的

<?php
if (isset($_GET["username"]))
{
  $user = $_GET["username"];
  echo $user;
  echo " is your username <br />";
}
else 
{
  $user = null;
  echo "no username supplied <br />";
}

if (isset($_COOKIE['myJavascriptVar'])) {
  echo "Cookie is " . $_COOKIE['myJavascriptVar'];
}

echo "<br />";

if (isset($_COOKIE['anothercookie'])) {
  echo "Another cookie is " . $_COOKIE['anothercookie'];
}

?>

我如何让cookie工作？
