html中实现图像浏览(javascript)

想看到这个例子,你需要有39-1.jpg,39-2.jpg的图片,然后复制一下代码到记事本中，然后另存为html格式就可以了

function load()
{
window.Text2.value = document.images[0].width;

}

function resize()
{
document.images[0].width = document.body.clientWidth-35;

function Submit1_onclick() {
document.images[0].width = document.images[0].width * 1.1;

function Submit2_onclick() {
document.images[0].width = document.images[0].width * 0.9;
}

function Submit3_onclick() {
document.images[0].width = document.body.clientWidth-35;
}

function Submit4_onclick() {
document.images[0].width = window.Text2.value;
}

function Button1_onclick() {
window.Text1.value ="1";
document.images[0].src = "39-1.jpg";
}

function Button4_onclick() {
window.Text1.value ="2";
document.images[0].src = "39-2.jpg";
}

function Button2_onclick() {
var n = window.Text1.value ;
n--;
if(n<1)
n=1;
window.Text1.value =n;
if(n==1)
document.images[0].src = "39-1.jpg";
if(n==2)
document.images[0].src = "39-2.jpg";

var n = window.Text1.value ;
n++;
if(n>2)

window.Text1.value =n;
