我想使div auto过期。我尝试下面的代码，但未成功。我在这里使用了php mysql和jquery。
<?php
require('dbconnection.php');
$output='';
$sql="select * from vacancy";
$res=mysqli_query($conn,$sql);
if(mysqli_num_rows($res)>0){
while($row=mysqli_fetch_assoc($res)){
?>
<div class="bs-calltoaction bs-calltoaction-primary" id="jobvacancydiv">
<script>
window.setInterval(function(){
var current = new Date();
var expiry = new Date("<?= $row['expdate'];?>");
if(current.getTime()>expiry.getTime()){
$('#jobvacancydiv').hide();
}
}, 5000);
</script>
</div>
参考方案
使用setTimeout，从两个日期中获取毫秒数，并将毫秒数传递给setTimeout。
function setToHappen(fn, d){
var t = d.getTime() - (new Date()).getTime();
return setTimeout(fn, t);
}
var date = new Date((Date.now() + 5000)); // hides div in 5 seconds
function hideDiv() {
$('#jobvacancydiv').hide();
}
setToHappen(hideDiv, date);#jobvacancydiv {
width: 300px;

使用PHP包含时的淡入淡出过渡 - php我正在尝试使用jQuery或CSS（或其他方式！）在DIV中包含的php页面上创建淡入淡出或滑动过渡。我四处搜寻，发现了很多淡入淡出过渡的示例，这些实例彼此淡入淡出div或隐藏内容淡入淡出，但是这种情况略有不同。我有一个DIV，其内容由导航栏控制。选中后，每个页面都可以使用PHP成功地包含在div中，但我想使内容淡入和淡出。关于如何在页面更改之间进行漂亮过渡…
