使用 javascript / jquery 滚动到页面顶部?

I've a <button> on the page, when this button is pressed a hidden <div> is shown using jQuery.

How do I scroll to the top of the page using a JavaScript/jQuery command in that function? It is desirable even if the scroll bar instantly jumps to the top. I'm not looking for a smooth scrolling.

    If you don't need the change to animate then you don't need to use any special plugins - I'd just use the native JavaScript window.scrollTo method -- passing in 0,0 will scroll the page to the top left instantly.

    window.scrollTo(x-coord, y-coord);
    

    Parameters

    • x-coord is the pixel along the horizontal axis.
    • y-coord is the pixel along the vertical axis.

    You could simply use a target from your link, such as #someid, where #someid is the div's id.

    Or, you could use any number of scrolling plugins that make this more elegant.

    http://plugins.jquery.com/project/ScrollTo is an example.

    You don't need jQuery to do this. A standard HTML tag will suffice...

    <div id="jump_to_me">
        blah blah blah
    </div>
    
    <a target="#jump_to_me">Click Here To Destroy The World!</a>

    If you do want smooth scrolling, try something like this:

    $("a[href='#top']").click(function() {
      $("html, body").animate({ scrollTop: 0 }, "slow");
      return false;
    });
    

    That will take any <a> tag whose href="#top" and make it smooth scroll to the top.

    With window.scrollTo(0, 0); is very fast
    so i tried the Mark Ursino example, but in Chrome nothing happens
    and i found this

    $('.showPeriodMsgPopup').click(function(){
        //window.scrollTo(0, 0);
        $('html').animate({scrollTop:0}, 'slow');//IE, FF
        $('body').animate({scrollTop:0}, 'slow');//chrome, don't know if Safari works
        $('.popupPeriod').fadeIn(1000, function(){
            setTimeout(function(){$('.popupPeriod').fadeOut(2000);}, 3000);
        });
    });
    

    tested all 3 browsers and it works
    i'm using blueprint css
    this is when a client clicks "Book now" button and doesn't have the rental period selected, slowly moves to the top where the calendars are and opens a dialog div pointing to the 2 fields, after 3sec it fades

    All of these suggestions work great for various situations. For those who find this page through a search, one can also give this a try. JQuery, no plug-in, scroll to element.

    $('html, body').animate({
        scrollTop: $("#elementID").offset().top
    }, 2000);

    Non-jQuery solution / pure JavaScript:

    document.body.scrollTop = document.documentElement.scrollTop = 0;

    You can try using JS as in this Fiddle http://jsfiddle.net/5bNmH/1/

    Add the "Go to top" button in your page footer:

    <footer>
        <hr />
        <p>Just some basic footer text.</p>
        <!-- Go to top Button -->
        <a href="#" class="go-top">Go Top</a>
    </footer>

    <a href="#top">go top</a>

    If you don't want smooth scrolling, you can cheat and stop the smooth scrolling animation pretty much as soon as you start it... like so:

       $(document).ready(function() {
          $("a[href='#top']").click(function() {
              $("html, body").animate({ scrollTop: 0 }, "1");              
              $('html, body').stop(true, true);
    
              //Anything else you want to do in the same action goes here
    
              return false;                              
          });
      });
    

    I've no idea whether it's recommended/allowed, but it works :)

    When would you use this? I'm not sure, but perhaps when you want to use one click to animate one thing with Jquery, but do another without animation? ie open a slide-in admin login panel at the top of the page, and instantly jump to the top to see it.

    Really strange: This question is active for five years now and there is still no vanilla JavaScript answer to animate the scrolling… So here you go:

    var scrollToTop = window.setInterval(function() {
        var pos = window.pageYOffset;
        if ( pos > 0 ) {
            window.scrollTo( 0, pos - 20 ); // how far to scroll on each step
        } else {
            window.clearInterval( scrollToTop );
        }
    }, 16); // how fast to scroll (this equals roughly 60 fps)
    

    If you like, you can wrap this in a function and call that via the onclick attribute. Check this jsfiddle

    Note: This is a very basic solution and maybe not the most performant one. A very elaborated example can be found here: https://github.com/cferdinandi/smooth-scroll

    A lot of users recommend selecting both the html and body tags for cross-browser compatibility, like so:

    $('html, body').animate({ scrollTop: 0 }, callback);
    

    This can trip you up though if you're counting on your callback running only once. It will in fact run twice because you've selected two elements.

    If that is a problem for you, you can do something like this:

    function scrollToTop(callback) {
        if ($('html').scrollTop()) {
            $('html').animate({ scrollTop: 0 }, callback);
            return;
        }
    
        $('body').animate({ scrollTop: 0 }, callback);
    }
    

    The reason this works is in Chrome $('html').scrollTop() returns 0, but not in other browsers such as Firefox.

    If you don't want to wait for the animation to complete in the case that the scrollbar is already at the top, try this:

    function scrollToTop(callback) {
        if ($('html').scrollTop()) {
            $('html').animate({ scrollTop: 0 }, callback);
            return;
        }
    
        if ($('body').scrollTop()) {
            $('body').animate({ scrollTop: 0 }, callback);
            return;
        }
    
        callback();
    }

    smooth scroll, pure javascript:

    (function smoothscroll(){
        var currentScroll = document.documentElement.scrollTop || document.body.scrollTop;
        if (currentScroll > 0) {
             window.requestAnimationFrame(smoothscroll);
             window.scrollTo (0,currentScroll - (currentScroll/5));
        }
    })();

  • You dont need JQuery. Simply you can call the script

    window.location = '#'
    

    on click of the "Go to top" button

    Sample demo:

    output.jsbin.com/fakumo#

    PS: Don't use this approach, when you are using modern libraries like angularjs. That might broke the URL hashbang.

    Why don't you use JQuery inbuilt function scrollTop :

    $('html, body').scrollTop(0);//For scrolling to top
    
    $("body").scrollTop($("body")[0].scrollHeight);//For scrolling to bottom
    

    Short and simple!

    Try this code:

    $('html, body').animate({
        scrollTop: $("div").offset().top
    }, time);
    

    div => Dom Element where you want to move scroll.

    time => milliseconds, define the speed of the scroll.

    If you want to do smooth scrolling, please try this:

    $("a").click(function() {
         $("html, body").animate({ scrollTop: 0 }, "slow");
         return false;
    });
    

    Another solution is JavaScript window.scrollTo method :

     window.scrollTo(x-value, y-value);
    

    Parameters :

    • x-value is the pixel along the horizontal axis.
    • y-value is the pixel along the vertical axis.

    None of the answers above will work in SharePoint 2016.

    It has to be done like this : https://sharepoint.stackexchange.com/questions/195870/

    var w = document.getElementById("s4-workspace");
    w.scrollTop = 0;

    Motivation

    This simple solution works natively and implements a smooth scroll to any position.

    It avoids using anchor links (those with #) that, in my opinion, are useful if you want to link to a section, but are not so comfortable in some situations, specially when pointing to top which could lead to two different URLs pointing to the same location (http://www.example.org and http://www.example.org/#).

    Solution

    Put an id to the tag you want to scroll to, for example your first section, which answers this question, but the id could be placed everywhere in the page.

    <body>
      <section id="top">
        <!-- your content -->
      </section>
      <div id="another"><!-- more content --></div>
    

    Then as a button you can use a link, just edit the onclick attribute with a code like this.

    <a onclick="document.getElementById('top').scrollIntoView({ behavior: 'smooth', block: 'start', inline: 'nearest' })">Click me</a>
    

    Where the argument of document.getElementById is the id of the tag you want to scroll to after click.
