jquery如何实现锚点链接之间的平滑滚动

复制代码 代码如下:

  $('a[href*=#]').click(function() {

  if (location.pathname.replace(/^\//, '') == this.pathname.replace(/^\//, '') && location.hostname == this.hostname) {

  var $target = $(this.hash);

  $target = $target.length && $target || $('[name=' + this.hash.slice(1) + ']');

  if ($target.length) {

  var targetOffset = $target.offset().top;

  $('html,body').animate({

  scrollTop: targetOffset

  },

  500);

  return false;

  }

  }

  });
