Change hash without reload in jQuery

开发者 https://www.devze.com 2022-12-14 17:32 出处:网络
I have the following code: $(\'ul.questions li a\').click(function(event) { $(\'.tab\').hide(); $($(this).attr(\'href\')).fadeIn(\'slow\');

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开发者_如何学编程 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?


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');
});

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


The accepted answer didn't work for me as my page jumped slightly on click, messing up my scroll animation.

I decided to update the entire URL using window.history.replaceState rather than using the window.location.hash method. Thus circumventing the hashChange event fired by the browser.

// Only fire when URL has anchor
$('a[href*="#"]:not([href="#"])').on('click', function(event) {

    // Prevent default anchor handling (which causes the page-jumping)
    event.preventDefault();

    if ( location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname ) {
        var target = $(this.hash);
        target = target.length ? target : $('[name=' + this.hash.slice(1) +']');

        if ( target.length ) {    
            // Smooth scrolling to anchor
            $('html, body').animate({
                scrollTop: target.offset().top
            }, 1000);

            // Update URL
            window.history.replaceState("", document.title, window.location.href.replace(location.hash, "") + this.hash);
        }
    }
});


You can set your hash directly to URL too.

window.location.hash = "YourHash";

The result : http://url#YourHash


You can simply assign it a new value as follows,

window.location.hash
0
