let scrollTop = document.documentElement.scrollTop || document.body.scrollTop; 1. 在线演示:https://mouday.github.io/front-end-demo/scroll/scrollTop.html 3、Element.scroll()/Window.scroll() scroll() 方法是用于滚动元素到某个特定坐标 文档:https://developer.mozilla.org/zh-CN/docs/Web/API/Elem...
3、在滚动条距离底端5%以内: scrollTop / (offsetHeight – clientHeight) >= 0.95 如果要实现拉到底部自动加载内容。只要注册个滚动条事件: scrollBottomTest =function(){ $("#contain").scroll(function(){ var $this =$(this), viewH =$(this).height(),//可见高度 contentH =$(this).get(0).sc...
$(window).scroll(function(event){ var wScrollY = window.scrollY; // 当前滚动条位置 var wInnerH = window.innerHeight; // 设备窗口的高度(不会变) var bScrollH = document.body.scrollHeight; // 滚动条总高度 if (wScrollY + wInnerH >= bScrollH) { showMore(); } }); //监听上下滚动 ...
function runToBottom(){ currentPosition=document.documentElement.scrollTop || document.body.scrollTop; currentPosition+=30; if(currentPosition<document.body.scrollHeight && (document.body.clientHeight + document.body.scrollTop < document.body.scrollHeight)) { //window.scrollTo(0,currentPosition); //...
function debounce(func, wait) { let timeout; return function(...args) { clearTimeout(timeout); timeout = setTimeout(() => func.apply(this, args), wait); }; } window.addEventListener('scroll', debounce(function() { if (getScrollBottom() >= document.body.offsetHeight) { console.log...
window.addEventListener('scroll', handleScroll) return () => { // 清除滚动事件监听 window.removeEventListener('scroll', handleScroll) } }, []) import React, { useEffect, useRef } from 'react'; function ScrollToBottomLoad() { const containerRef = useRef(null); useEffect(() => { funct...
条的dom(functionsmoothscroll() {constcurrentScroll = domWrapper.scrollTop;// 已经被卷掉的高度constclientHeight = domWrapper.offsetHeight;// 容器高度constscrollHeight = domWrapper.scrollHeight;// 内容总高度if(scrollHeight -10> currentScroll + clientHeight) {window.requestAnimationFrame(smoothscroll);...
} Scroll to Bottom <!-- 页面内容 --> <!-- 这里放置大量内容 --> function scrollToBottom() { window.scrollTo({ top: document.body.scrollHeight, behavior: 'smooth' }); } 可能遇到的问题及解决方法 问题:页面没有平滑滚动到指定位置。 原因: 浏览器不支持scroll-behavior属性。
window.scrollTo(0,0); clearInterval(timer); } } function runBottom(){ currentPosition2=document.documentElement.scrollTop || document.body.scrollTop; currentPosition2+=50; if(currentPosition2>0) { window.scrollTo(0,currentPosition2); } else { window.scrollTo(0,0); clearInterval(timer2)...
if(top<scrollBottom){ 显示 } 例:图片延时加载 function getPos(obj){ var t =0; var l =0; while(obj){ t+=obj.offsetTop; l+=obj.offsetLeft; obj=obj.offsetParent; } return {top:t,left:l}; } window.onload=function(){ var aImg = document.getElementsByTagName('img'); ...
