jquery历史记录实现代码

(function($){
var origcontent = "";
function loadcontent(hash) {
if(hash != "") {
if(origcontent == "") {
origcontent = $('#content').html();
}
$('#content').load(hash +".html",
function(){ prettyprint(); });
} else if(origcontent != "") {
$('#content').html(origcontent);
}
}
$(document).ready(function() {
$.history.init(loadcontent);
$('#navigation a').click(function(e) {
var url = $(this).attr('href');
url = url.replace(/^.*#/, '');
$.history.load(url);
return false;
});
});
})(jquery);
