Effects together with smooth scroll

Asked

I would like to put other effects following the scroll. Below follows the code I’m using and that just does the scroll. How can I use more effects within that code. Bounce for example.

var $doc = $('html, body');
$('.scrollSuvave').click(function() {
    $doc.animate({
        scrollTop: $( $.attr(this, 'href') ).offset().top
    }, 1200);
    return false;
});

  • I advise you not to implement this, browsers have Addons or native flags to simulate this already.

  • Diego. Do you mean to put more effects beyond the scroll? Just leave the scroll?

  • Do you want to add smooth scrolling to the mouse bearing? , or do you want a smooth scroll to show an off-screen item?

  • I already have a smooth scroll. I want to add another effect when arriving at the end of the scroll. When you click on the link the scroll starts and when you get to the section I want it to have an effect. Bounce for example. Making the section have this effect in the scroll sequence. It became clearer?

You can check the positioning in the scroll event and call your animation depending on the placement:

  window.addEventListener('scroll', function (e) {
     var windowOffsetTop
     var triggered = false
     //  verifica se é crhome ou firefox para ver onde está a posição da 
     //   window
     if (!!window.chrome && !!window.chrome.webstore) {
         windowOffsetTop = e.path[1].pageYOffset
     } else if (typeof InstallTrigger !== 'undefined') {
         windowOffsetTop = e.pageY
     } 

     // verifica posicionamento da window e se a função já foi disparada         
     if (windowOffsetTop >= 300 && !triggered) {
        triggered = true
         // chame a sua animacao aqui
        console.log("animation")
     }
  })

Refer to the easing types to change the shape that Animate takes on. https://api.jqueryui.com/easings/

var easing = "easeOutBounce";
$doc.animate({
     scrollTop: $( $.attr(this, 'href') ).offset().top
}, 1200, easing);
return false;

Remembering that it is necessary to import jquery-ui together.

<head>
    <script src="jquery.min.js"></script>
    <link rel="stylesheet" href="jquery-ui.min.css">
    <script src="jquery-ui.min.js"></script>
</head>

The file you download in https://jqueryui.com/download/all/

Other options

To perform another animation after the finish you can add right after the first, that they will be placed in a queue by jquery, and when one finishes the next animation will be executed.

$doc.animate({
    scrollTop: $( $.attr(this, 'href') ).offset().top
}, 1200).animate({
    scrollTop: 0
}, 1200);

,or use the option of the oncomplete of the Animate

var oncomplete = function(){
     //código que será executado após o término da animação de scroll
}

$doc.animate({
   scrollTop: $( $.attr(this, 'href') ).offset().top
}, 1200, easing, oncomplete);
return false;

, or use a Timeout with scroll time

setTimeout(oncomplete,1200);

  • Please. I could write the example of "Remembering that it is necessary to import jquery-ui together." Because I must have done something wrong. I put this code in the JS file var easing = "easeOutBounce"; $doc.Animate({ scrollTop: $( $.attr(this, 'href') ).offset().top }, 1200, easing); Return false; as directed. as it did not turn I must have done or failed to do something. rsrs

  • To add the jquery-ui just add <script src="jquery-ui.min.js"></script> in the header right after the jquery import. And CSS also <link rel="stylesheet" href="jquery-ui.min.css">

  • It’s a doughnut. Rs. I made it in Head <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <script src="jquery-ui.min.js"></script> <link rel="stylesheet" href="jquery-ui.min.css"> Before the</body> <script="text/javascript" src="js/main.js"></script> and in the main.js file we have: var easing = "easeInBounce"; $doc.Animate({ scrollTop: $( $.attr(this, 'href') ).offset().top }, 1200, easing); Return false; P fav where I went wrong. Ob.

  • managed to implement with jquery easing plugin. Thanks for the tips.

You can use the plugin jQuery Easing Plugin (version 1.3) (included in the example below) which has a list of effects. Below I used the easeInBounce:

var $doc = $('html, body');
$('.scrollSuvave').click(function() {
    $doc.animate({
        scrollTop: $( $.attr(this, 'href') ).offset().top
    }, 1200, "easeInBounce");
    return false;
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
