我有一个正在制作的网站,页面中央有一个 vimeo 视频,旁边有一个菜单。所以,它最终会变成一个全白的页面,中间有这个黑色矩形。

该网站是为艺术家而设的。我试图让他工作的不同图像在黑色矩形周围的不同位置淡入和淡出(除了美学之外别无他法)。菜单简单明了,页面极其简约。图片在不同地方淡入淡出会给它“一些东西”......一种令人难以忘怀的效果。

我找到了随机化代码,但我不希望一张图片能够背靠背出现。我希望它从一个图像开始,然后移动到其他 5 个图像,然后返回到第一个图像。大多数按顺序淡入淡出的东西都没有放在不同的位置(这是我遇到问题的地方)。我的代码可以正常工作,但是一旦我将图像放置在周围(使用“绝对”定位),就会出现问题。

当尝试实现可随时在线获得的帮助时,它并没有按照我的要求进行。

我想我可以尝试从字面上只调用每个图像的相同代码的更改版本(只需更改绝对位置和计时器),但这似乎没有必要。似乎我也无法无限循环。

对于我的帖子冗长,我深表歉意,但我只是想澄清一下,关于淡入/淡出图像的“易于查找”的脚本和帖子并不能解决我的问题。我找了又找都无济于事。

我知道我的代码根本不起作用,但这是我最近一次使用它的地方。提前致谢!

最佳答案

这并不完美,但应该可以帮助您入门。它循环遍历一组图像并更改一个 img 标签上的 src。然后它会随机选择一个顶部和左侧的位置并将图像淡入和淡出。 http://jsfiddle.net/bhlaird/TH7t7/3/

Javascript:

var images = [{
src: "http://placeKitten.com/g/500/500",
width: 500,
height: 500
}, {
src: "http://placeKitten.com/g/300/300",
width: 300,
height: 300
}, {
src: "http://placeKitten.com/g/600/600",
width: 600,
height: 600
}, {
src: "http://placeKitten.com/g/400/400",
width: 400,
height: 400
}, , {
src: "http://placeKitten.com/g/200/200",
width: 200,
height: 200
}];


var counter = {
val: 0,
top: 0,
left: 0
};

function getRandomInt(min, max) {
return Math.floor(Math.random() * (max - min + 1)) + min;
}

function fadeImage(counter) {
counter.top = getRandomInt(0, $("body").height() - images[counter.val].height);
counter.left = getRandomInt(0, $("body").width() - images[counter.val].width);

$("#haunting").fadeTo(2000, 0.3).delay(1000).fadeOut(2000);
$("#haunting").attr({
src: images[counter.val].src
}).css({
top: counter.top,
left: counter.left
});

if (counter.val < images.length) counter.val++;
else counter.val = 0;


}
setInterval(function () {
fadeImage(counter);
}, 6000);

HTML:

<img id="haunting" style="display:none" src="http://placeKitten.com/g/500/200" />
<div id="video">
<img src="http://placekitten.com/200/200" />
<div id="menu">Some text</div>
</div>

CSS:

html, body {
height: 100%;
}
#video {
margin: auto;
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
width:200px;
height:210px;
text-align:center;
}
#haunting {
position: absolute;
top:0;
left:0;
}
