我试图弄清楚如何在500毫秒后从一个图像切换到另一个图像。我目前在图像之间切换,但我希望每个图像显示500毫秒,并使第二个图像在500毫秒后消失,而不是让它循环。这就是我现在所拥有的:
<html>
<head>
<title>loop</title>
<script type = "text/javascript">
function displayNextImage() {
x = (x === images.length - 1) ? 0 : x + 1;
document.getElementById("img").src = images[x];
}
function displayPreviousImage() {
x = (x <= 0) ? images.length - 1 : x - 1;
document.getElementById("img").src = images[x];
}
function startTimer() {
setInterval(displayNextImage, 500);
}
var images = [], x = -1;
images[0] = "image1.jpg";
images[1] = "image2.jpg";
</script>
</head>
</html>
<body onload = "startTimer()">
<img id="img" src="image1.jpg">
</body>
</html>
任何人都可以帮我解决这个问题吗?谢谢!

这应该做你想做的事情:
<html>
<head>
<title>loop</title>
<script type = "text/javascript">
var images = [];
var x = 0;
var $img = document.getElementById("img");
images[0] = "image1.jpg";
images[1] = "image2.jpg";
function displayNextImage() {
if (++x < images.length) {
$img.src = images[x];
setInterval(displayNextImage, 500);
}
else {
$img.remove();
}
}
function startTimer() {
setInterval(displayNextImage, 500);
}
</script>
</head>
</html>
<body onload = "startTimer()">
<img id="img" src="image1.jpg">
</body>
</html>
