JS代码
// 构建索引值 var currIndex = 0; // 初始化点击事件 initClick(); function initClick() { $(".banner-img li").hover(function () { $(".banner-body").stop().slideUp(); clearInterval(timer); },function () { timer = setInterval("banner()",3000); $(".banner-body").stop().slideDown(); }) $('#bannerUl li').click(function(){ $(this).addClass("active"); $(this).siblings().removeClass("active"); $(".banner-img li").eq($(this).index()).addClass("show"); $(".banner-img li").eq($(this).index()).siblings().removeClass("show"); $(".banner-text div").eq($(this).index()).addClass("text-active"); $(".banner-text div").eq($(this).index()).siblings().removeClass("text-active"); currIndex = $(this).index(); clearInterval(timer); timer = setInterval("banner()",3000); }); } //构建定时器 var timer = setInterval("banner()",3000); function banner() { if (currIndex > 3) { currIndex = 0; } else { currIndex ++; } $(".banner-img li").eq(currIndex).addClass("show"); $(".banner-img li").eq(currIndex).siblings().removeClass("show"); $("#bannerUl li").eq(currIndex).addClass("active"); $("#bannerUl li").eq(currIndex).siblings().removeClass("active"); $(".banner-text div").eq(currIndex).addClass("text-active"); $(".banner-text div").eq(currIndex).siblings().removeClass("text-active"); }
