<pre><code>&lt;script type="text/javascript"&gt;
   var i=0;
   function add_input()
        {
          if(i!=6){
              var d=document.getElementById('div');

           d.innerHTML+="&lt;input type='text'  name='addtext"+i+"' id='addtext"+i+"'onkeyup='copy("+i+")'&gt;&lt;br&gt;&lt;/br&gt;";
                 i++;
                 }

        }
  function copy(j){

           var mm = 'addtext'+j;
           var divid = 'newcontent'+j;
           var s1=document.getElementById(mm).value;

           /*var s2=document.getElementById('newcontent'+j);*/
           var s2=document.getElementById('newcontent'+j);

           s2.innerHTML=s1;


            }
          &lt;/script&gt;


      &lt;script type="text/javascript"&gt;
          function f2() {

               if(document.getElementById('newcontent0').style.fontWeight =='bold')
                    {
                         document.getElementById('newcontent0').style.fontWeight = 'normal';
                    }
                   else if(document.getElementById('newcontent0').style.fontWeight =='normal')
                     {
                        document.getElementById('newcontent0').style.fontWeight = 'bold';
                      }
                  else if(document.getElementById('newcontent0').style.fontWeight =='')
                     {
                        document.getElementById('newcontent0').style.fontWeight = 'bold';
                      }
              }
             &lt;/script&gt;

     &lt;input  type="button" value="Add Text" onclick="add_input()"  /&gt;
