Ajax Question

jquery ajax call on click, only works once

I have this simple jquery code. On click it gets the URL of the tag, loads that page next to the current content, slides it and removes the old content.
The state of the page is EXACTLY the same as before, same elements no extra classes or styles.
The problem is that the next ajax call just doesn't work. Maybe I need to .unbind() something?

I'm new to jquery and javascript so i'm quite lost. Thanks a lot for your help :)

<script type="text/javascript">
$(document).ready(function(){
loadPage();
});
function loadPage(url) {
if (url == undefined) {
$('body').load('index.html header:first,#content,footer', hijackLinks);
} else {
$.get(url , function(data) {
$('body').append(data);
$('body>meta').remove();
$('body>link').remove();
$('body>title').remove();
$('body').append(direction);
sm = $(window).width();
if(direction == "leftnav"){
$('body>header:last,body>#content:last,footer:last').css("left", "-" + sm + "px");
footerheight = $('body>#content:last').outerHeight(false) + $('body>header:last').outerHeight(true) ;
$('footer:last').css("top", footerheight);
$('body>header,body>#content,footer').css("-webkit-transition-duration","0.5s")
$('body>header,body>#content,footer').css("-webkit-transform","translate(" + sm + "px,0px)");
};
if(direction != "leftnav"){
$('body>header:last,body>#content:last,footer:last').css("left", sm + "px");
footerheight = $('body>#content:last').outerHeight(false) + $('body>header:last').outerHeight(true) ;
$('footer:last').css("top", footerheight);
$('body>header,body>#content,footer').css("-webkit-transition-duration","0.5s")
$('body>header,body>#content,footer').css("-webkit-transform","translate(-" + sm + "px,0px)");
};
setTimeout(function(){
$('body>header:not(:last),body>footer:not(:last),body>#content:not(:last)').remove()
},500);
setTimeout(function() {
$('body>header,body>footer,body>#content').removeAttr('style')
},500);
});
}
}
function hijackLinks() {
$('a').click(function(e){
e.preventDefault();
loadPage(e.target.href);
direction = $(this).attr('class');
});
}
</script>

Answer

Since you are loading content dynmically which is replacing the contents of your body your event handler is most likely is not going to remain.

To fix this you need to adjust your click handler to use either live() or delegate()

$('a').live("click", function(e){
    e.preventDefault();
    loadPage(e.target.href);
    direction = $(this).attr('class');

});
