一、确定DIV大小
body {
margin: 0;
padding: 0;
}
#event-types {
width: 300px;
height: 180px;
}
二、JS定时刷新背景;
window.onload = function () {
var imgs = ["images/event0.jpg", "images/event1.jpg", "images/event2.jpg"];
var i = 0;
var head = document.getElementById("event-types");
head.style.background = "url(images/event0.jpg)";
function time() {
i++;
i = i % 3;
head.style.background = "url(" + imgs[i] + ")";
}
setInterval(time, 6 * 1000);
}
