  </code></pre>
  
  <p><strong>page 2</strong></p>
  
  <pre><code>&lt;form name="myform2" id="myform2" method="GET"&gt;
  &lt;input type="text" name="Place" value="&lt;?php echo $_GET[Place] ?&gt;"&gt;//
  &lt;input type="text" name="type" value="&lt;?php echo $_GET[Type] ?&gt;"&gt;
  &lt;button id="submit2"type="submit" value="submit2" name="submit2" onclick="return ss()"&gt;
  </code></pre>
  
  <p>js1</p>
  
  <pre><code>$(document).ready(function(){ // load file.php on document ready     
       function sssssss2(page){
            var form2 = document.myform2;
            var dataString1 = $(form2).serialize() + '&amp;page=' + page;
           ({
           type: "GET",
           url: "file.php",//
           data: dataString1,
           success: function(ccc){
               $("#search_results").html(ccc);
          }});}
      sssssss2(1) ;
      $('#search_results .pagination li.active').live('click',function(){
          var page = $(this).attr('p');
          sssssss2(page);                 
      });  
  });
  </code></pre>
