仿迅雷焦点广告效果(JQuery版)

首先是JS代码部分，之前一定先引入JQuery包：

$(document).ready(function(){
var imgUrl = new Array();
var title = new Array();
var description = new Array();
var imgLink = new Array();
var local;
var count;
local = 1; //指针位置
count = 7; //图片数量
imgUrl[1] = “Images/ceshi.jpg”;
imgUrl[2] = “Images/ceshi1.jpg”;
imgUrl[3] = “Images/ceshi.jpg”;
imgUrl[4] = “Images/ceshi1.jpg”;
imgUrl[5] = “Images/ceshi.jpg”;
imgUrl[6] = “Images/ceshi1.jpg”;
imgUrl[7] = “Images/ceshi.jpg”;
title[1] = “测试一下1”;
title[2] = “测试一下2”;
title[3] = “测试一下3”;
title[4] = “测试一下4”;
title[5] = “测试一下5”;
title[6] = “测试一下6”;
title[7] = “测试一下7”;
description[1] = “描述一下1”;
description[2] = “描述一下2”;
description[3] = “描述一下3”;
description[4] = “描述一下4”;
description[5] = “描述一下5”;
description[6] = “描述一下6”;
description[7] = “描述一下7”;
imgLink[1] = “ceshi1.asp”;
imgLink[2] = “ceshi2.asp”;
imgLink[3] = “ceshi3.asp”;
imgLink[4] = “ceshi4.asp”;
imgLink[5] = “ceshi5.asp”;
imgLink[6] = “ceshi6.asp”;
imgLink[7] = “ceshi7.asp”;
function showImage(){
$(“#Buttons div”).each(function(){
if($(this).attr(“id”) == “B”+local){
$(this).attr(“class”,”Menu_On”);
$(this).addClass(“active”);
$(“#AdImage”).attr(“src”,imgUrl[local]);
$(“#AdTitle a”).html(title[local]);
$(“#AdDescription a”).html(description[local]);
$(“#Images a”).attr(“href”,imgLink[local]);
}else{
$(this).removeClass(“active”);
$(this).attr(“class”,”Menu_Off”);
}
});
local++;
if(local > count){
local = 1;
}
theTimer = setTimeout(function(){showImage()},3000);
}
$(“#Buttons div”).click(function(){
local = $(this).attr(“id”).replace(“B”,””);
var cid = $(this).attr(“id”);
$(“#Buttons div”).each(function(){
if($(this).attr(“id”) == cid){
$(this).addClass(“active”);
$(“#AdImage”).attr(“src”,imgUrl[$(this).attr(“id”).replace(“B”,””)]);
$(“#AdTitle a”).html(title[$(this).attr(“id”).replace(“B”,””)]);
$(“#AdDescription a”).html(description[$(this).attr(“id”).replace(“B”,””)]);
