我选择带有滚动条的选项标签来查看下拉列表中的内容。我希望当我们单击选择项目时,滚动条应位于底部。
jquery code $('document').ready(function(){ $('#textin1').click(function() { var pos = $('#textin1').offset(); pos.top += $('#textin1').width(); $('#dropdown').fadeIn(100); $('#dropdown').scrollTop($('#dropdown').find('li:contains("'+$('#textin1').val()+'")').position().top); return false; }); $('#dropdown li').click(function() { $('#textin1').val($(this).text()); $('#dropdown li').removeClass('selected'); $(this).addClass('selected'); $(this).parent().fadeOut(100); }); });

试试这个也许对你有用
const scrolling = document.getElementById("scroll"); const config = { childList: true }; const callback = function (mutationsList, observer) { for (let mutation of mutationsList) { if (mutation.type === "childList") { window.scrollTo(0, document.body.scrollHeight); } } }; const observer = new MutationObserver(callback); observer.observe(scrolling, config);
