javascript - 带偏移量的平滑滚动 anchor (jquery)

Question

我使用以下代码为我网站上的 anchor 添加平滑滚动。因为我有一个粘性标题 ID 喜欢用 200px 来抵消它

$('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;
        }
    }
});

尝试在 scrollTop 动画中添加或删除一个值

$('a[href*="#"]:not([href="#"])').click(function() {
    var offset = -200; // <-- change the value here
    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 + offset
            }, 1000);
            return false;
        }
    }
});
