Change hash without reload in jquery

Question

Hello,

I have the following code:-

$('ul.questions li a').click(function(event) {
 $('.tab').hide();
 $($(this).attr('href')).fadeIn('slow');
 event.preventDefault();
 window.location.hash = $(this).attr('href');
});

This simply fades a div in based on when you click but i want the page url hash tag to change when you click so people can copy and bookmark it. At the moment this effectively reloads the page when the hash tag is change.

Is it possible to change the hash tag and not reload the page to prevent the jumping effect?

Thanks

Dave.

Answer 1

You could try catching the onload event. And stopping the propagation dependent on some flag.

var changeHash = false;

$('ul.questions li a').click(function(event) {
    var $this = $(this)
    $('.tab').hide();  //you can improve the speed of this selector.
    $($this.attr('href')).fadeIn('slow');
    StopEvent(event);  //notice I've changed this
    changeHash = true;
    window.location.hash = $this.attr('href');
});

$(window).onload(function(event){
    if (changeHash){
        changeHash = false;
        StopEvent(event);
    }
}

function StopEvent(event){
    event.preventDefault();
    event.stopPropagation();
    if ($.browser.msie) {
        event.originalEvent.keyCode = 0;
        event.originalEvent.cancelBubble = true;
        event.originalEvent.returnValue = false;
    }
}

Not tested, so can't say if it would work

This works for me

$('ul.questions li a').click(function(event) {
    event.preventDefault();
    $('.tab').hide();
    window.location.hash = this.hash;
    $($(this).attr('href')).fadeIn('slow');
});
