网站锚点执行平滑滚动操作，jquery有示例，不做赘述了，也可以使用以下代码测试
$(function() {$('a[href*="#"]:not([href="#"])').click(function() {if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {var target = $(this.hash);target = target.length ? target : $('[name=' + this.hash.slice(1) +']');if (target.length) {$('html, body').animate({scrollTop: target.offset().top}, 1000);return false;}}});});
还可以这样
/* SMOOTH SCROLL TO ANCHOR */$(function(){$('a[href*=#]:not([href=#])').on('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){ $('html,body').animate({scrollTop:target.offset().top-50},1000); return false; };};});});
