JS如何实现左右滚动轮播代码详细点
var datas = [
{imgSrc:"（图片 ）"},
{imgSrc:"（图片 ）"},
{imgSrc:"（图片 ）"},
{imgSrc:"（图片 ）"},
{imgSrc:"（图片 ）"},
{imgSrc:"（图片 ）"}
];
var banner = document.getElementById("banner");
var list = document.getElementById("list");
for(var i = 0,len = datas.length;ilen;i++){
var div = document.createElement("div");
var li = document.createElement("li");
if(i==0){ //默认第一项轮播项显示 对应的控制按钮被选中
div.className = "item active";
li.className = "active";
}else{ //其他项隐藏 其他的控制按钮样式不改变
div.className = "item";
li.className = "";
}
div.innerHTML = 'a href="' + datas[i].targetSrc + '"' +
'img src="' + datas[i].imgSrc + '" /' +
'/a';
li.innerHTML = i + 1;
banner.appendChild(div);
list.appendChild(li);
}
var lunBo = document.getElementById("lunBo");
var items = document.querySelectorAll("#lunBo #banner .item");
var lis = document.querySelectorAll("#lunBo #list li");
var currentIndex = 0;//(控制按钮和轮播项共同的索引)
for(var i = 0,len = lis.length;ilen;i++){
lis[i].index = i;
lis[i].onmouseenter = function(){
currentIndex = this.index;
for(var j = 0;jlen;j++){
lis[j].className = "";
items[j].className = "item";
}
this.className = "active";
items[this.index].className = "item active";
}
}
var termId; //全局变量
function autoPlay(){
termId = setInterval(function(){
currentIndex++;
if(currentIndex==lis.length){
currentIndex = 0;
}
lis[currentIndex].onmouseenter();
},3000);
}
autoPlay();//打开页面自动轮播
//鼠标进入停止轮播
lunBo.onmouseenter = function(){
clearInterval(termId);
}
//鼠标离开继续轮播
lunBo.onmouseleave = function(){
autoPlay();
}

3.页面调用：
script type="text/javascript" src="js/jquery-1.9.1.js"/script
script type="text/javascript" src="js/jquery.imgScroll.js"/script(上面那个js)
$('.lbCon .lbBox .lbList').imgScroll({
firstDiv: '.lbCon .lbBox',
scrollBox: '.lbCon .lbBox .lbList',
scrollImgBox: '.lbCon .lbBox ul',
botPrev: '.lbCon .lbPrev',
botNext: '.lbCon .lbNext',
changeType: "slide",
thumbNowClass: 'on',
thumbOverEvent: true,
changeTime: 5000,
ImgBoxMar: 0,
flag: false
});
4.至于鼠标滑过 显示左右按钮,可以这么写（思路:css默认隐藏左右按钮，鼠标滑过显示左右按钮，划出隐藏，需要引入jquery.js）
$(function(){
$(".wj_jdt_1").bind("onmouseover",function(){
$(".ctr_btn").show();
}).bind("onmouseout",function(){
$(".ctr_btn").hide();
})
})
大体是这么个意思，至于怎么延伸在你
