JS
定義變量和定時(shí)器,變量等價(jià)于eq(index)中index,自動(dòng)輪播是可以的,關(guān)鍵在于,鼠標(biāo)進(jìn)入選項(xiàng)卡區(qū)域時(shí)候,怎么對(duì)應(yīng)想要的輪播畫面,
方法:停止定時(shí)器,獲取當(dāng)前選項(xiàng)卡下標(biāo),匹配對(duì)應(yīng)的輪播畫面顯示出來(lái)。
var a=0;var t=null;$(function(){ $('.fours>a:not(:first-child)').hide(); t=setInterval("autoMove()",2000); //鼠標(biāo)進(jìn)入輪播停止 $('.parent').hover(function(){clearInterval(t)},function(){t=setInterval("autoMove()",2000);});// 當(dāng)鼠標(biāo)進(jìn)去對(duì)應(yīng)選項(xiàng)時(shí)候圖片對(duì)應(yīng)變化 $(".top p>a").hover(function(){ clearInterval(t); var num=$(this).index(); showThis(num); //console.log(num); })});function autoMove(){ a++; if(a>=4){ a=0; } play(a);}function play(a){ $('.fours>a').filter(":visible").fadeOut(500).parent().children().eq(a).fadeIn(1000); $('.top p a').eq(a).addClass("selected").siblings().removeClass("selected");}//鼠標(biāo)進(jìn)入的情況function showThis(sum){ $(".fours>a").eq(sum).fadeIn(1000).siblings().fadeOut(500); $(".top p a").eq(sum).addClass("selected").siblings().removeClass("selected");}
以上這篇jQuery實(shí)現(xiàn)選項(xiàng)聯(lián)動(dòng)輪播效果【附實(shí)例】就是小編分享給大家的全部?jī)?nèi)容了,希望能給大家一個(gè)參考,也希望大家多多支持武林網(wǎng)。
