JQuery实现在同一页面锚点链接之间的平滑滚动

$(document).ready(function() { 
$('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 
}, 
1000); 
return false; 
} 
} 
}); 
});
