Please see the below code.
On page load, I am having three dropdowns for month, week and year.
Then depending upon the selection and button submit will change the values for <div id="datesdiv> and <div id="data">.

1. Problem is if I use form post method , after form submit, if I refresh the page, alert message will apeear saying "page cannot be refreshed without resending the information.

2. Problem2: If I use Get Method, alert will be gone, but in the case form values are passing in the url: I dont want that url will have any variables passed.

Please make changes in the code so that either of the methods will work.

<form id="Frm" onSubmit="report(this,true);" method="post">
<input type="hidden" id="refreshed" value="no">
<input type="hidden" id="date1" name="date1" />
<input type="hidden" id="date2" name="date2" />
<select name="month" id="month" onChange="setDate(this.form)">
<option value="1">January
<option value="2">February
<option value="3">March
<option value="4">April
<option value="5">May
<option value="6">June
<option value="7">July
<option value="8">August
<option value="9">September
<option value="10">October
<option value="11">November
<option value="12">December
<select name="week" style="width:180px;">
<option value="1">week of April6
<option value="2">week of april20

here is another suggestion:

Here are some suggestions from the Experts Exchange web site, but
as you don't want to change anything with the JavaScript or the form
code, it isn't going to do you any good.  Trying to find a fix on the
browser side is not going to be the solution, and as I already stated,
there are several things (POST v GET, various frame and JavaScript
conditions) that can cause this problem, all of which requires changes
to one part of the page code or another.

Some snippets follow:

<%@ Language="VBScript" %>
<% Response.Expires= -1
Response.AddHeader "Cache-Control", "no-cache"
Response.AddHeader "Pragma", "no-cache" %>

"You should put the Response.clear at the bottom of the page ..."

"Does a <body onLoad="init()">  script help?
In that function init() you can clear the fields or set them to
default state."

<%Response.CacheControl="Public"%> did the trick.

It didn't work at first but when I removed
Response.AddHeader "Cache-Control", "no-cache"
... it worked just as

well i suppose since this is all javascript, you could add a reset method to your page

i.e. "Does a <body onLoad="init()">  script help?

and create an init method that clears all values

what did you put inside of init()?

Init is a javascript method you have to implement.

function init()
         //make all controls value = '' or null
