How to add javascript into specific posts/pages ??

I have two page. In first page – a simple form with three input text fields. And i want the values of these fields into another page with the same values of the form. The first page form is

<form name="parameters" method="GET" action="second-page-url">
      <p> Login:
        <input type="text" name="login" value="">
      </p>
      <p> Password:
        <input type="text" name="password" value="">
      </p>
	  <p> Email:
        <input type="text" name="email" value="">
      </p>
	<p>
        <input type="submit" name="submit" value="Send data">
      </p>
    </form>

And for Second Page – the form is

<h2>Received: </h2>
<form name="parameters" method="GET" action="">
<fieldset>
      <p> Login:
        <input type="text" name="login" value="" id="login">
      </p>
      <p> Password:
        <input type="text" name="password" value="" id="password" readonly>
      </p>
	  <p> Email:
        <input type="text" name="email" value="" id="email" readonly>
      </p>
     </fieldset>
    </form>

and below this form I used the javascript code to get the values of the first page’s form into the second page form.

<script language="JavaScript">

		var parameters = location.search.substring(1).split("&");

		var temp = parameters[0].split("=");
		l = unescape(temp[1]);

		temp = parameters[1].split("=");
		c = unescape(temp[1]);

		temp = parameters[2].split("=");
		e =  unescape(temp[1]);

		temp = parameters[3].split("=");
		p =  unescape(temp[1]);

		document.getElementById("login").value = l;
		document.getElementById("password").value = c;
		document.getElementById("email").value = e;

</script>

Please help – Or how it can be achieved?
