我创建了一个 HTML 文件,它使用 java 脚本来显示随机显示在 3 个 div 标签中的图像。单击图像向左或向右移动。在我在页面中使用单个幻灯片之前它工作正常,但是当我在同一页面上尝试多个幻灯片时会产生问题。
这是一张幻灯片的代码:
**<script>
currentIndx = 2;
MyImages=new Array();
MyImages[0]='1images2.jpeg';
MyImages[1]='1images3.jpeg';
MyImages[2]='1images4.jpeg';
MyImages[3]='artwork.jpg';
MyImages[4]='1images5.jpeg';
imagesPreloaded = new Array(4)
for (var i = 0; i < MyImages.length ; i++)
{
imagesPreloaded[i] = new Image(120,120)
imagesPreloaded[i].src=MyImages[i]
}
/* we create the functions to go forward and go back */
function Nexter()
{
if (currentIndx<MyImages.length-1){
alert(currentIndx);
document.leftimg.src=document.middleimg.src
document.middleimg.src=document.rightimg.src
document.rightimg.src=imagesPreloaded[++currentIndx].src
}
else {
alert("In nexter else")
currentIndx=0
document.leftimg.src = document.middleimg.src
document.middleimg.src = document.rightimg.src
document.rightimg.src = imagesPreloaded[currentIndx].src
}
writeImageNumber();
}
function Backer()
{
if (currentIndx>0)
{
--currentIndx;
alert("In Backer If");
document.rightimg.src=document.middleimg.src
document.middleimg.src=document.leftimg.src
document.leftimg.src=imagesPreloaded[currentIndx].src
}
else
{
currentIndx = MyImages.length-1
alert(MyImages.length +"else");
document.rightimg.src = document.middleimg.src
document.middleimg.src = document.leftimg.src
document.leftimg.src = imagesPreloaded[currentIndx].src
}
writeImageNumber();
}
/*###### function to reload the images and text when refresh is pressed ##### */
function setCurrentIndex()
{
currentIndx=0;
document.theImage.src=MyImages[0];
document.form1.text1.value=Messages[0];
writeImageNumber();
}
</script>
<body onload="setCurrentIndex();automaticly()">
<!-- start of form for image slide show ####################### -->
<div id ="left" style="float:left">
<a href="#" onclick="Backer()" ><img src="1images2.jpeg" width="265" height="262"
border="0" name="leftimg"></a>
</div>
<div id ="middle" style="float:left">
<a href="#" onclick=""><img src="1images3.jpeg" width="265" height="262"
border="0" name="middleimg"></a>
</div>
<div id ="right" class="compimg" style="float:left">
<a href="#" onclick="Nexter()" ><img src="1images4.jpeg"
width="265" height="262" alt="" border="0"name="rightimg"></a>
</div>
<!-- end of form for image slide show ####################### -->**
Any suggestions...
