我遇到了一些代码和旧 js 的问题。我复制了网页并更改了代码，但是在新文件中选择了相应的缩略图时，大图像下没有出现文本：http: //jsfiddle.net/dEW75/
<script type="text/javascript">
function swapImage(imgID)
{
var itemImage = document.getElementById('itemImage');
var itemText = document.getElementById('itemText');
var itemCaption = document.getElementById('itemCaption');
itemImage.src = "images/finishing_touches/color_stain/textured/textured" + imgID + "_sm.jpg";
if(imgID == 1)
{
itemText.innerHTML = 'Latitude East';
itemCaption.innerHTML = ''};
if(imgID == 2)
{
itemText.innerHTML = 'Summer Breeze';
itemCaption.innerHTML = ''};
if(imgID == 3)
{
itemText.innerHTML = 'Winter Cherry';
itemCaption.innerHTML = ''};
if(imgID == 4)
{
itemText.innerHTML = 'Autumn Leaves';
itemCaption.innerHTML = ''};
if(imgID == 5)
{
itemText.innerHTML = 'Boardwalk';
itemCaption.innerHTML = ''};
if(imgID == 6)
{
itemText.innerHTML = 'Driftwood';
itemCaption.innerHTML = ''};
if(imgID == 7)
{
itemText.innerHTML = 'Canvas Linen';
itemCaption.innerHTML = ''};
if(imgID == 8)
{
itemText.innerHTML = 'Linen Flaxseed';
itemCaption.innerHTML = ''};
if(imgID == 9)
{
itemText.innerHTML = 'Silver Flannel';
itemCaption.innerHTML = ''};
if(imgID == 10)
{
itemText.innerHTML = 'Onyx';
itemCaption.innerHTML = ''};
if(imgID == 11)
{
itemText.innerHTML = 'East Indian Laurel';
itemCaption.innerHTML = ''};
if(imgID == 12)
{
itemText.innerHTML = 'Sandalwood';
itemCaption.innerHTML = ''};
if(imgID == 13)
{
itemText.innerHTML = 'Nora Creek Oak';
itemCaption.innerHTML = ''};
if(imgID == 14)
{
itemText.innerHTML = 'Midnight Espresso';
itemCaption.innerHTML = ''};
}

当在此页面上选择缩略图时，我需要文本显示在大图像下方：http: //jsfiddle.net/qVGFV/
