单击以水平滚动到元素

Question

我正在尝试按下按钮时创建水平滚动DIV,它将滚动到相应的DIV ID.

我使用了以下代码,但它的行为非常错误,例如,如果您单击第2部分,然后在第2部分单击3.

我需要左边的部分是200px,而不是在左边滚动到0px.我认为这导致我遇到问题.

这是在行动中看到它的小提琴

滚动内容时,偏移位置实际上会随着元素移动而改变,因此您永远无法获得正确的位置.

解决方案是使用已经滚动的数量来计算正确的位置,或者只是存储初始偏移量,这似乎更容易

$(function () {
    $('.nav a').each(function() {
        $(this).data('left', $($(this).attr('href')).offset().left);
    }).on('click', function (event) {
        var $anchor = $(this);
        $('#content').stop().animate({
            scrollLeft: $anchor.data('left') - 200
        }, 1000);
        event.preventDefault();
    });
});
