关键代码

<script>
    //定义页面所有锚点点击平滑滚动
    $(function () {
        $('a[href*=#],area[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;
                }
            }
        });
    })


    //定义页面某元素下的所有锚点点击平滑滚动
    $(function () {
        $('.maodian a[href*=#]').click(function () {
            $(this).addClass('cur').siblings().removeClass('cur');
            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;
                }
            }
        });
    })
