我正在尝试将JavaScript倒计时添加到表中，该表位于php foreach中
我的php代码是这样的：
<?php
global $wpdb, $indeed_db;
$user = wp_get_current_user();
$userid = $user->ID;
$woo_orders = $wpdb->get_results("SELECT * FROM wp8u_wc_order_product_lookup");
foreach ($woo_orders as $print ){
$order_id = $print->order_id;
$woo_customer_id = $print->customer_id;
$woo_customer = $wpdb->get_results("SELECT * FROM wp8u_wc_customer_lookup where customer_id=$woo_customer_id");
foreach($woo_customer as $print2){
$current_user_uid = $print2->user_id;
}
$date1 = strtotime($print->date_created);
$date2 = strtotime("+1 months", $date1);
$date_created = date('Y-m-d H:i:s', $date1);
$date_after = date('Y-m-d H:i:s', $date2);
$amount = $print->product_net_revenue;
if($userid == $current_user_uid){
?><table>
<tr>
<th>Order ID</th>
<th>My ID</th>
<th>My Customer ID</th>
<th>Create Date</th>
<th>Date After 1 Month</th><
<th>Amount</th>
</tr>
<tr>
<td><?php echo "$order_id";?></td>
<td><?php echo "$current_user_uid";?></td>
<td><?php echo "$woo_customer_id";?></td>
<td><?php echo "$date_created";?></td>
<td><?php echo "$date_after";?></td>
<td><?php echo "$amount";?></td>
<td id="demo2"></td>
</tr>
</table><?php
}
}
?>
这是我上面的php代码的输出：
Order ID | My ID | My Customer ID | Create Date | After 1 month | Amount | Timer |
126 37 9 2020-06-24 13:45:35 2020-07-24 13:45:35 3000
Order ID | My ID | My Customer ID | Create Date | After 1 month | Amount | Timer |
123 37 9 2020-06-22 12:01:14 2020-07-22 12:01:14 1000
因此，我试图在“计时器”列下的两行中添加倒数计时器
这是我的Java脚本倒数计时器代码：
<script>
function createCountDown(elementId, date){
var countDownDate = new Date(date).getTime();
var x = setInterval(function(){
var now = new Date().getTime();
var distance = (countDownDate) - (now);
var days = Math.floor(distance / (1000 * 60 * 60 * 24));
var hours = Math.floor((distance % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
var minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60));
var seconds = Math.floor((distance % (1000 * 60)) / 1000);
document.getElementById(elementId).innerHTML = days + "d " + hours + "h " + minutes + "m " + seconds + "s ";
if (distance < 0)
{
clearInterval(x);
document.getElementById(elementId).innerHTML = "SUCCESS";
}
}, 1000);
}createCountDown("demo", <?php echo "$date_after"; ?>)
</script>
如何将此JavaScript倒数计时器添加到表中？
答案 0 :(得分：0)
尝试一下：
createCountDown("demo", <?= "'{$date_after}'"; ?>)
答案 1 :(得分：0)
我迅速完成了一个演示，展示了如何在不使用ID属性的情况下实现目标。我假设表中的每一行都应该显示一个倒数计时器？
sql，btw，看起来像是join的合适候选者-这意味着只使用一个查询，但这完全是另一回事–只是以为我提到过。
如果您复制/运行此程序，则应该了解其工作原理-生成的表包含伪数据。
