问题描述
我正在寻找的是一种使HTML标头标签每隔几秒钟更改背景图像的方法.只要不复杂，任何解决方案都是受欢迎的.
What I'm looking for is a way to make my HTML header tag change background images every few seconds. Any solutions are welcome, as long as it is not to complex.
我现在有以下代码，并且链接到JQuery:
I have this code right now as well as linking to JQuery:
<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
$(function() {
var header = $(‘.mainHeader’);
var backgrounds = new Array(
‘url(img/rainbow.jpg)’,
‘url(img/chickens_on_grass.jpg)’
‘url(img/cattle_on_pasture.jpg)’
‘url(img/csa_bundle.jpg)’
);
var current = 0;
function nextBackground() {
header.css(‘background’,backgrounds[current = ++current % backgrounds.length]);
setTimeout(nextBackground, 10000);
}
setTimeout(nextBackground, 10000);
header.css(‘background’, backgrounds[0]);
});
我的HTML标头:
<header class="mainHeader"></header>
和CSS:
.mainHeader {
background: no-repeat center bottom scroll;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
min-height: 150px;
padding-top: 2%;
font-size: 100%;
}
现在我已经有了背景图片.
Right now I have now background image at all.
