用偏移(jQuery)平滑滚动锚

Question

im使用以下代码在我的网站上添加平滑滚动。因为我有一个粘性标题ID喜欢用200px

来抵消这一点

$('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;
        }
    }
});

Answer 1

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;
        }
    }
});

一个更简单的示例，没有哈希是：

$(document).on('click', 'a[href^="#"]', function (event) {
    event.preventDefault();
    $('html, body').animate({
        scrollTop: $($.attr(this, 'href')).offset().top + -200
    }, 1000);
});
