javascript - load Content with jQuery without refresh -

i want load content(is html) jquery. why following code not worked me?
use of tutorial: http://net.tutsplus.com/tutorials/javascript-ajax/how-to-load-in-and-animate-content-with-jquery/

html:
click on each of link load page it(href).

<div id="icon">     <a href="http://localhost/test/test2.php" id="delete_icon"></a>     <a href="<?=base_url();?>admin/tour/insert_foreign" id="add_icon" ></a>     <a href="http://localhost/test/1st.htm" id="edit_icon" ></a>     <a href="http://localhost/test/index1.php" id="print_icon"></a>     </div> 

js:

var hash = window.location.hash.substr(1); var href = $('#nav li a').each(function () {     var href = $(this).attr('href');     if (hash == href.substr(0, href.length - 5)) {         var toload = hash + '.html #content';         $('#content').load(toload)     } });  $('#icon a').click(function () {      var toload = $(this).attr('href') + ' #content';     $('#content').hide('fast', loadcontent);     $('#load').remove();     $('#wrapper').append('<span id="load">loading...</span>');     $('#load').fadein('normal');     window.location.hash = $(this).attr('href').substr(0, $(this).attr('href').length - 5);      function loadcontent() {         $('#content').load(toload, '', shownewcontent())     }      function shownewcontent() {         $('#content').show('normal', hideloader());     }      function hideloader() {         $('#load').fadeout('normal');     }     return false;  }); 

first of all:

• what not working?
• are getting errors?
• is xhr firing properly? (see http://fixingthesejquery.com/#slide33 debugging tips)

if want question answered should include relevant information possible.

secondly, looking @ code quickly:

you need pass reference function callback functions, instead invoking functions (shownewcontent() instead of shownewcontent), , passing whatever returns (in case, nothing).

try instead:

function loadcontent() {     $('#content').load(toload, '', shownewcontent); }  function shownewcontent() {     $('#content').show('normal', hideloader); }
