问题:

I'm trying to create a scrolling effect where when the onclick event is triggered, I want that div1 to scroll to dev2. It should initially go slowly and then fast!.

Here's a website using this effect: http://community.saucony.com/kinvara3/

How do I do this?

回答1:

$.fn.animateScrollDivs = function(sourceDiv, destinationDiv) {
  var source = '#' + sourceDiv;
  var destination = '#' + destinationDiv;

  $('html, body').animate({
    scrollTop: $(destination).offset().top
  }, 1200, 'easeInExpo');

};

function animateDiv(sourceDiv, destinationDiv) {

  $.fn.animateScrollDivs(sourceDiv, destinationDiv);

}

div {
  height: 650px;
  width: 1000px;
}
button {
  background-color: #FE2EF7;
}
.downButton {
  margin-top: 500px;
  margin-bottom: 40px;
  margin-right: 200px;
  margin-left: 200px;
}
.upButton {
  margin-top: 60px;
  margin-bottom: 500px;
  margin-right: 200px;
  margin-left: 200px;
}

<body>
  <div id="div1" style="background-color:red;">
    <button class="downButton" onclick="animateDiv('div1','div2');">Go Down</button>
  </div>
  <div id="div2" style="background-color:yellow;">
    <button class="upButton" onclick="animateDiv('div2','div1');">Go Up</button>
    <button class="downButton" onclick="animateDiv('div2','div3');">Go Down</button>
  </div>
  <div id="div3" style="background-color:grey;">
    <button class="upButton" onclick="animateDiv('div3','div2');">Go Up</button>
    <button class="downButton" onclick="animateDiv('div3','div4');">Go Down</button>
  </div>
  <div id="div4" style="background-color:#2E9AFE;">
    <button class="upButton" onclick="animateDiv( 'div4', 'div1');">GoToTop</button>
  </div>
</body>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js "></script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.11.1/jquery-ui.min.js "></script>

Will this do?? Please adjust the position of button(s) as per your requirement.

I've used jQuery mmin (1.11) and jQuery UI (1.11).

Make use of ScrollTop with offset().top to scroll it to DIV nodes.

HTML

Do add a "active" class on DIV item which you want to show at first on page load. For me, it's the first DIV item.

<button class="giu">Animate To Next available List Item</button>

<div class="product active" id="product1">1</div>
<div class="product" id="product2">2</div>
<div class="product" id="product3">3</div>
<div class="product" id="product4">4</div>

JavaScript

$('.giu').click(function(event) {
    event.preventDefault();
    var n = $(window).height();
    $('div.active').removeClass('active').next('div').addClass('active');
    $('body').animate({
        scrollTop: $(".product.active").offset().top
    }, 500);
});
