JavaScript scroll to div with animation

Question

I have a PhoneGap application that when it opens an HTML page, I want it to scroll to a specific <div> element. So far I've been able to make it do that with this script using jQuery:

<script>
$(document).delegate('.ui-page', 'pageshow', function () {
     var offset = $(this).find('#timeindicatordiv').offset().top;
     setTimeout(function () {
        $.mobile.silentScroll(offset);
        }, 0);
     });
</script>

This only gives me a jump directly to the <div> which looks a bit choppy.

Is there any way to give this a smooth animation?

Answer 1

You can do the following:

var scrollToElement = function(el, ms){
    var speed = (ms) ? ms : 600;
    $('html,body').animate({
        scrollTop: $(el).offset().top
    }, speed);
}

// specify id of element and optional scroll speed as arguments
scrollToElement('#timeindicatordiv', 600);

Answer 2

像这样做：

$("html,body").animate({scrollTop: offset}, 600);

Answer 3

 $('.click').click(function(l){ // prevent default action l.preventDefault(); scrollToElement( $(this).attr('href'), 2000 ); }); var scrollToElement = function(el, ms){ var speed = (ms) ? ms : 2000; $('html,body').animate({ scrollTop: $(el).offset().top }, speed); } 

 div { margin-top:1000px; } div:last-child { padding-bottom:1000px; }
