本文實(shí)例為大家分享了javascript+CSS實(shí)現(xiàn)輪播圖效果的具體代碼，供大家參考，具體內(nèi)容如下

1.html

<ul ></ul>

2.css

ul{ list-style:none; position: absolute; padding: 0; left: 0; right: 0; bottom: 0; top:0; margin:auto; width: 800px; height:200px;}

3.js

//生成輪播圖export function generateBanner(){ let sz = new Array(); let cur_ul = document.getElementById(’banner’); const recommends = this.recommends; let timer = setInterval(getNextLi, 3000); //生成輪播圖li for (let i = 0; i < recommends.length; i++) { //生成標(biāo)簽 let cur_li = document.createElement('li'); let cur_img = document.createElement('img'); //追加屬性 cur_img.src = recommends[i].pic; //追加樣式 cur_li.style.position = ’absolute’; cur_li.style.left = ’0px’; cur_li.style.transitionDuration = ’0.4s’; cur_li.style.cursor='pointer'; //ul總寬800 ，顯示一張完整的400px 兩張不完整的200px cur_img.style.width = ’125px’; cur_img.style.height = '100px'; //追加子元素 cur_li.appendChild(cur_img); cur_ul.appendChild(cur_li); //全部放入數(shù)組好操作 sz.push(cur_li); } //生成兩個(gè)圖標(biāo) generateAngleIcons(); //將最后三張圖片用來(lái)顯示 let len = sz.length - 1; //倒數(shù)第三張 showThreeLi(); //獲取下一個(gè)li顯示，將第一個(gè)放到數(shù)組最后 function getNextLi() { const li = sz[0]; sz = sz.slice(1); sz.push(li); //所有l(wèi)i還原 for (let i = 0; i < sz.length; i++) { //li全部還原成原始大小 sz[i].style.transform = 'scale(1)'; sz[i].style.left = '0px'; //從小到大li依此覆蓋 sz[i].style.zIndex = i; //全部隱藏 sz[i].style.display = 'none'; } //顯示最后三張 showThreeLi(); } //顯示最后三張 function showThreeLi() { sz[len - 2].style.left = '0px'; //倒數(shù)第二張 sz[len - 1].style.left = '120px'; sz[len - 1].style.zIndex = 100; sz[len - 1].style.transform = 'scale(1.3)'; //倒數(shù)第一張 sz[len].style.left = '230px'; //顯示 sz[len - 2].style.display = 'block'; sz[len - 1].style.display = 'block'; sz[len].style.display = 'block'; } function generateAngleIcons(){ const icons = new Array(); for (let i = 0; i < 2; i++) { //生成圖標(biāo)li let cur_li = document.createElement('li'); //追加樣式 cur_li.style.position = ’absolute’; cur_li.style.top = ’0px’; cur_li.style.bottom = ’0px’; cur_li.style.margin = 'auto'; cur_li.style.paddingTop='100px'; cur_li.style.paddingBottom='100px'; cur_li.style.zIndex = 20; icons.push(cur_li); } icons[0].style.left = ’0px’; icons[1].style.right = ’0px’; icons[0].innerHTML = ’<i class='angle left icon'></i>’ icons[1].innerHTML = ’<i class='angle right icon'></i>’ cur_ul.appendChild(icons[1]); cur_ul.appendChild(icons[0]); }}
