Use jQuery/JS selector by css classes instead of IDs since this line

<apex:inputField value="{!objOpportunity .Amount_Requested__c}" id="box1"/>

generates something like this

<input type="text" value="..." id="jjjs_nnd_box1...." />

due to apex form so that's why your jQuery selectors don't work.

For example, for your elements you need to do something like this

BOX1:

<apex:inputField value="{!objOpportunity .Amount_Requested__c}" styleClass="box1"/>

BOX2:

 <apex:inputField value="{!objOpportunity.Amount_Requested__c}"  styleClass="box2"/>

Note, I used styleClass attibute instead of id also your JS should be looks like:

       $(function(){
          $("input.box1").keypress(function()
          {
        $("input.box2").val($(this).val());
          }    
       });

Hope this helps you.

It is not working . I have a js code <script> function copy_data(val){ var a = document.getElementById(val.id).value alert("var"+a); document.getElementById("ptest").value=a } </script> And it is giving me error on web console"Uncaught TypeError: Cannot set property 'value' of null". – Shantanu Mahajan Jul 31 '15 at 6:56
What kind of JS code you are posting now? Is it related to your post? I suggested you to find an element by css classes instead of ids. We cannot write JS code for you. – Ruslan Vekua Jul 31 '15 at 7:15
Yes it is related to my post.. – Shantanu Mahajan Jul 31 '15 at 7:34
Ah. Better to ask for specifically what you want! Here's a link to the instructions on best practices on asking questions: salesforce.stackexchange.com/help/how-to-ask . I will amend my answer. – Ruslan Vekua Jul 31 '15 at 7:42

You also need to use noConflict to prevent the $ from clashing with internal Salesforce variables used on the page.

Try this:

var j$ = jQuery.noConflict();
j$(function(){
    j$("#box1").keypress(function(){
        j$("#box2").val($(this).val());
    } 
    ....etc
