我正在尝试创建一个具有背景图像的页面,该图像使用css封面属性,以便它在浏览器中响应,但不会失真但是从jQuery中的数组中随机选择。
我没有太多代码,因为这是我目前唯一正在做的事情,我一直在玩,但我对jQuery没有太多处理,所以我真的不知道是什么我在做!任何帮助表示赞赏!
HTML:
<head>
<title>Test</title>
<link href="css/css.css" rel="stylesheet">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="javascript/jquery.js"></script>
</head>
<body>
<div id="background">
</div>
</body>
CSS:
body {
margin: 0;
}
#background {
width: 100%;
height: 100%;
margin: 0;
background-repeat: no-repeat;
background-size: cover;
background-image: url(backgroundImage)
}
html, body {
overflow: none !important;
overflow-x: none !important;
overflow-y: none !important;
}
jQuery的:
var picArr = ['Images/IMG_3764.jpg', 'Images/IMG_3793.jpg', 'Images/IMG_4050.jpg', 'Images/IMG_4323.jpg', 'Images/IMG_4351.jpg', ];
var myNumber = Math.floor(Math.random() * 5);
$(document).ready(function () {
$("background-image").attr('url', picArr[myNumber]);
});

如果要将其随机化,请使用setTimeout()
此外,要更改&#34;背景&#34; div,只是.css jquery选择器,如下所示。
例如
var picArr = ['Images/IMG_3764.jpg', 'Images/IMG_3793.jpg', 'Images/IMG_4050.jpg', 'Images/IMG_4323.jpg', 'Images/IMG_4351.jpg', ];
$(document).ready(function () {
setTimeout(function(){
var myNumber = Math.floor(Math.random() * 5) + 1;
$("#background").css('background-image', 'url('+picArr[myNumber]+')'); //here
}, 3000); // ms of how often you want it to change.
});

你没有错误地选择了$("background-image")
,这不应该是$("#background")
var picArr = ['Images/IMG_3764.jpg', 'Images/IMG_3793.jpg', 'Images/IMG_4050.jpg', 'Images/IMG_4323.jpg', 'Images/IMG_4351.jpg', ];
var myNumber = Math.floor(Math.random() * 5);
$(document).ready(function () {
$("#background").attr('url', picArr[myNumber]); //here
});
#background {
width: 100%;
height: 100%;
margin: 0;
background-repeat: no-repeat;
background-size: cover;
background-image: url(backgroundImage)
}
<link href="css/css.css" rel="stylesheet">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="javascript/jquery.js"></script>
<div id="background">
</div>

我想这已经回答了,但这是我的解决方案:
`RDD that travels through time to compute things faster`
<强> CSS:强>
var picArr = ['http://lorempixel.com/output/fashion-q-c-640-480-1.jpg', 'http://lorempixel.com/output/animals-q-c-640-480-4.jpg', 'http://lorempixel.com/output/nightlife-q-c-640-480-2.jpg'];
var l = picArr.length;
var myNumber = Math.floor(Math.random() * l);
console.log(myNumber);
$(document).ready(function () {
$("#background").attr('style', 'background: url(' + picArr[myNumber]) + ')';
});
