这篇文章主要为大家详细介绍了html 实现5秒倒计时跳转首页,具有一定的参考价值,可以用来参考一下。
HTML经测试代码如下:
<div id="J_topBn" class="site-bn site-bn-20160224">
<div class="container clearfix">
<div class="site-bn-main">
<h2 class="title">四海网</h2>
<p class="desc">512pic十余项黑科技,很轻狠快</p>
<div class="links"><a class="btn-link-common btn-link" href="http://www.q1010.com">立即打开</a></div>
</div>
<div class="close-box">
<a class="close J_closeBn" href="javascript:void(0);"><i class="iconfont">关闭</i></a>
<span class="counter J_counter"></span>
</div>
</div>
</div>
<div id="J_topBackdrop" class="site-bn-backdrop J_closeBn"></div>
css经测试代码如下:
.site-bn{display:none;position:fixed;_position:absolute;top:0;left:0;z-index:99;width:100%}
.site-bn .container{position:relative}
.site-bn-backdrop{display:none;position:fixed;_position:absolute;top:0;left:0;z-index:98;width:100%;height:1000px;background:#000;opacity:.3;filter:alpha(opacity=30)\9}
.site-bn-20160224{height:100%;background-color:#fff;background-color:rgba(255,255,255,0.95);filter:progid:DXImageTransform.Microsoft.gradient(startColorstr="#f2ffffff",endColorstr="#f2ffffff")\9;-webkit-font-smoothing:antialiased}
.site-bn-20160224 .close-box{position:absolute;top:72px;right:225px;text-align:right;color:#ff6700}
.site-bn-20160224 .close{display:inline-block;*zoom:1;*display:inline;width:24px;height:24px;line-height:24px;border:1px solid #ff6700;font-size:12px;text-align:center;color:#ff6700}
.site-bn-20160224 .counter{display:block;line-height:2}
.site-bn-20160224 .btn-link{display:inline-block;*zoom:1;*display:inline;width:196px;height:48px;border:1px solid #ff6700;line-height:48px;text-align:center;color:#ff6700;font-size:16px}
.site-bn-20160224 .site-bn-main{margin-top:115px;text-align:center}
.site-bn-20160224 .site-bn-main .title{margin:0 0 10px;font-size:70px;color:#ff6700;line-height:1;font-family:'F5bfdf';font-weight:normal}
.site-bn-20160224 .site-bn-main .desc{margin:0 0 70px;font-size:20px;color:#ff6700}
.site-bn-bar{width:100%}
.site-bn-bar .container{position:relative}
.site-bn-bar .site-bn-bar-link{display:inline-block;*zoom:1;*display:inline;width:115px;height:32px;font-size:12px;line-height:32px;text-align:center;color:#fff;background:#000;vertical-align:4px}
.site-bn-bar .site-bn-bar-close{position:absolute;right:0;top:7px;width:46px;height:46px;font-size:28px;line-height:46px;text-align:center;background-color:#f1410a;color:#fff;opacity:.6;filter:alpha(opacity=60)\9}
JS经测试代码如下:
jQuery(function($){
var $topBn = $('#J_topBn'),
$topBnBackdrop = $('#J_topBackdrop'),
$counter = $('.J_counter'),
$closeBnTrigger = $('.J_closeBn'),
timeoutTopBn,
bnCounter = 5;
function countDown(){
bnCounter -=1;
if(bnCounter < 1){
closeBn();
}else{
$counter.text(bnCounter + ' 秒后关闭');
}
}
function closeBn(){
var expireDate = 7;
window.clearInterval(timeoutTopBn);
$counter.remove();
$topBn.animate({'top':-$topBn.height()},1000,function(){
$topBn.hide();
$topBnBackdrop.hide();
});
// $.cookie('indexTopBn', '1', {
// expires: expireDate
// });
}
function initTopBar(){
$topBn.show();
$topBnBackdrop.height($(document).height()).show();
timeoutTopBn = window.setInterval(function(){
countDown();
},1000);
$closeBnTrigger.on('click',function(e){
e.preventDefault();
closeBn();
})
}
initTopBar();
});
