本文实例讲述了jQuery实现平滑滚动到指定锚点的方法。分享给大家供大家参考。具体如下：

定义好指定的anchor锚点，调用下面的js代码可以让页面平滑的滚动到指定的位置，非常实用，比如返回页面顶部，去往页面底部等功能

// HTML:
// 
Lorem Ipsum

// 
Back to Top

$(document).ready(function() {
  $("a.topLink").click(function() {
    $("html, body").animate({
      scrollTop: $($(this).attr("href")).offset().top + "px"
    }, {
      duration: 500,
      easing: "swing"
    });
    return false;
  });
});
Copy after login

希望本文所述对大家的jQuery程序设计有所帮助。
