Working with search suggestion

I have the following search suggestion script, where as a user types dynamically the result is updated. What I would want is that when a user click on one of the suggestion it takes them to the `following:searchPage.php?user_query=what the user has typed in the input

Below is the script

$(function(){
$(".search").keyup(function() 
{ 
var searchid = $(this).val();
var dataString = 'search='+ searchid;
if(searchid!='')
{
  $.ajax({
  type: "POST",
  url: "search.php",
  data: dataString,
  cache: false,
  success: function(html)
  {
  $("#result").html(html).show();
  }
  });
}return false;    
});

jQuery("#result").live("click",function(e){ 
  var $clicked = $(e.target);
  var $name = $clicked.find('.name').html();
  var decoded = $("<div/>").html($name).text();
  $('#searchid').val(decoded);
});
jQuery(document).live("click", function(e) { 
  var $clicked = $(e.target);
  if (! $clicked.hasClass("search")){

    window.open('searchPage.php?user_query=','_self',false);
  }
});
$('#searchid').click(function(){
  jQuery("#result").fadeIn();
});
});

At its current state it just open the window to searchPage.php but doesn;t take into account in the url what the user has entered; the desired result is searchPage.php?user_query=what ever you want
