I am sending POST form data to Page 2 from Page 1.
Page_1.html
<head>
    <script type="text/javascript">
        function sendForm()
        {
            document.forms["form1"].submit();
        }
    </script>
</head>
<body>
    <form action="Page_2.html" method="POST" name="form1">
        <input type="hidden" name="t1" value="123">
        <br>
        <input type="button" onClick="sendForm()" id="t2">
    </form>
</body>
Now, how can I retrieve the value of the text "t1" in the Page_2.html?
