JS自动切换图片代码问题

js代码如下，里面有详细解释：

script type="text/javascript"

/**

1. 图片自动切换(更改img标签src属性)

a.制作一个切换函数

b.加载事件，完成间歇函数功能

2. 完成图片停止功能

3. 如果鼠标移出图片，则间隙函数要调动起来

4. 图片切换的时候对应的序号需要高亮显示

5. 当鼠标"移入"一个序号，则图片要显示对应序号的图片

当前序号也需要被高亮显示

序号有鼠标移入事件

6. 鼠标从序号移出要继续图片切换

//图片切换功能

var i = 1;

function pic_change(){

//图片如果到达最后一个张，则计数器清空、归位

i++;

if(i8){

i=1;

}

//全部序号"暗"下来

var lis = document.getElementsByTagName('li');

for(var j=0; jlis.length; j++){

lis[j].style.background="green";

}

//当前序号背景色高亮显示

document.getElementById('xu'+i).style.background="yellow";

var pic_obj = document.getElementById('pic');

pic_obj.src=i+".jpg";

}

//加载事件函数，完成页面每次加载间歇函数的制作

var timer = "";

function jia(){

clearInterval(timer);

timer = setInterval('pic_change()', 1000);

}

//停止图片切换

function stop_pic(){

clearInterval(timer);

}

//鼠标移入序号发生变化的函数

//1显示当前序号对应图片

//2当前序号高亮

//3鼠标移出图片要继续切换

function xu_change(n){

//显示图片

document.getElementById('pic').src=n+".jpg";

//立即停止间隙函数

stop_pic();

//序号背景色发生变化

//全部序号"暗"下来

var lis = document.getElementsByTagName('li');

for(var j=0; jlis.length; j++){

lis[j].style.background="green";

}

//当前序号背景色高亮显示

document.getElementById('xu'+n).style.background="yellow";

//让图片切换与当前序号一致计数器与当前序号一致就可以

i=n;

}

图片自动切换的JS代码

试试这个图片切换

有12345数字一起切换

鼠标点一下数字会变换到另一张图片，不点就会自动换

里面有教程和源码

自己改图片链接和大小~~

求纯js 图片切换代码，最好带注释！

现在所有图片都是放在images文件家里的。

你的图片要是不是放在images文件夹里的话，比如要放在tupian文件夹里，你就在dw里替换所有images字符为tupian，就能显示小箭头了啊

JS实现点击一个按钮更换图片

你的代码差在少了"选择元素"这一步。

img1.src = "..images/DT2.JPG"这一步是没有作用的，因为img1你还没有定义。

正确的方法是让图片元素的id是img1，然后

document.getElementById('img1').src = "..images/DT2.JPG"

这样进行赋值。

document.getElementById('img1')这一步的作用就是选择图片元素。

这是针对此问题的测试页面

代码如下

div class="DT"

div

img id="img1" src=""

/div

div style="text-align:center"

input type="button" id="b1" value=" 放大 " onclick="fd();" /

input type="button" id="b3" value="还原 " onclick="hy();" /

input type="button" id="b2" value=" 缩小 " onclick="sx();" /

/div

function fd() {

document.getElementById('img1').src = ""

}

function sx() {

document.getElementById('img1').src = ""

}

function hy() {

document.getElementById('img1').src = ""

}
