html簡單的跑馬燈效果
阿新 • • 發佈:2019-01-24
很多專案中都會遇到有類似跑馬燈效果的訊息輪播展示,做了一個簡單的訊息輪播展示。
主要程式碼如下:
html
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title>跑馬燈效果</title>
<meta name="viewport" content="initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0, user-scalable=no, width=device-width" >
<link href="css/index.css" type="text/css" rel="stylesheet">
</head>
<body>
<div class="g-winner-roll">
<img src="img/tongzhi.png">
<div class="m-countdown">
</div>
</div>
<script src="js/jquery.min.js"></script>
<script src ="js/index.js"></script>
</body>
</html>
css
.g-winner-roll{
height: 30px;
border-bottom: 1px solid #d3d3d3;
background-color: #ffffff;
}
.g-winner-roll img{
float: left;
margin-left: 10px;
margin-top: 7px;
display: block;
width: 15px;
height: 15 px;
}
.m-countdown{
margin-left: 25px;
width: 100%;
height: 30px;
}
.m-countdown > a{
text-align: left;
margin-left: 10px;
height: 30px;
line-height: 30px;
font-size: 12px;
position:absolute;
display: none;
}
.m-countdown > a:first-child{
display: block;
}
.m-countdown > a >span{
color: rgb(128,128,128);
height: 30px;
}
index.js

$(function(){
var list = ["跑馬燈效果資料1","跑馬燈效果資料2","跑馬燈效果資料3","跑馬燈效果資料4","跑馬燈效果資料5","跑馬燈效果資料6"];
var htmlString ="";
for(var i=0;i<list.length;i++){
htmlString += '<a href="#"><span>'+list[i]+'</span></a>';
}
$(".m-countdown").html(htmlString);
showRollling();
});
function showRollling(){
var height = 40; //這個數字是輪播圖片的高度
var animationTime = 600; //這個數字是動畫時間
var marginTime = 2000; //這個數字是間隔時間
var nowimg = 0; //訊號量
var mytimer = null;
//將圖片列表中的第一個節點複製,然後追加到佇列的最後。
//$(".m-countdown a:first-child").clone().appendTo(".m-countdown");
var mytimer = window.setInterval(
function(){
youanniu();
}
,marginTime
);
<!--計時器暫停方法-->
// window.clearInterval(mytimer);
// mytimer = window.setInterval(
function youanniu(){
if(!$(".m-countdown a").is(":animated")){
//折騰訊號量
if(nowimg < $(".m-countdown a").length - 1){
nowimg = nowimg + 1;
showAnimate(nowimg);
}else{
nowimg = 0;
$(".m-countdown a").each(function(index){
if(index==0){
$(this).css("display","block");
}
else {
$(this).css("display","none");
}
}).css("top","7px");
}
}
}
function sho![這裡寫圖片描述](http://img.blog.csdn.net/20160807012707902)wAnimate(index) {
$(".m-countdown a").eq(index).css("display","block");
$(".m-countdown a").eq(index-1).animate(
{
"top": -height * nowimg
}
, animationTime
);
}
}
效果:
