我有一个静态页面,我用它来查看图片,javascript会播放幻灯片;但是,我想将图片转储到同一目录中,当打开页面时,javascript将创建一个包含所有图片的数组,而不必为每个场景编辑数组....这可能吗?...我知道javascript在从本地文件系统读取时有一些安全限制。这里是静态页面和javascript
<!doctype html>
<html lang="en">
<head>
<title>Picture Show</title>
<link type="text/css" rel="stylesheet" href="stylesheet.css" />
<script type="text/javascript" src="slideshow.js"></script>
</head>
<body>
<!-- Insert your content here -->
<div id="container">
<div id="header">
<h1>Slide Show</h1>
<a id="link" href="javascript:slideShow()"></a>
</div>
<div id="slideShow">
<img name="image" alt="Slide Show" src="pics/0.jpg" />
</div>
</div>
</body>
</html>
的javascript
//javascript code for slideshow
//pictures
var imgs = [ "pics\/0.jpg", "pics\/1.jpg", "pics\/2.jpg", "pics\/3.jpg", "pics\/4.jpg", "pics\/5.jpg" ];
var imgNum = 0;
var imgsLength = imgs.length-1;
var time = 0;
//changing images function
function changeImg(n) {
imgNum += n;
//last position of array
if (imgNum > imgsLength) {
imgNum = 0;
}
//first position of array
if (imgNum < 0) {
imgNum = imgsLength;
}
//console.log(images.tagName);
document.image.src = imgs[imgNum];
return false;
}
//slideshow function
function slideShow() {
var tag = document.getElementById('link').innerHTML;
if(tag == "Stop") {
clearInterval(time); //stoping slideshow
document.getElementById('link').innerHTML = "Start";
document.getElementById('link').style.background = "yellow";
}
else { //all other cases come here
time = setInterval("changeImg(1)", 4000);
document.getElementById('link').innerHTML = "Stop";
document.getElementById('link').style.background = "green";
}
}
window.addEventListener('load', slideShow);

由于安全问题,无法使用浏览器内的javascript自动读取目录。你有两个选择:
