Question

我在我的网站上设置了自定义计时器。我想做两个计时器。我尝试复制整个代码并将其粘贴在下面，但它没有做任何事情，尝试了其他方法，但没有产生我想要的结果。

我已经开始学习Javascript和php。

这是我的代码

     <div id="container">
        <a name="top" id="top"></a>
        <div id="header">           
            <div id="logo">
                <div class="wrapper">
                    <a href="{$mybb->settings['bburl']}/index.php"><img src="{$theme['logo']}" alt="{$mybb->settings['bbname']}" title="{$mybb->settings['bbname']}" /></a><br />           


                </div>
            </div>
            <div id="panel">
                <div class="upper">
                    <div class="wrapper">                       
                        {$welcomeblock}
                    <!-- </div> in header_welcomeblock_member and header_welcomeblock_guest -->
                <!-- </div> in header_welcomeblock_member and header_welcomeblock_guest -->
            </div>
        </div>
        <div id="content">
            <div class="wrapper">
                {$pm_notice}
                {$bannedwarning}
                {$bbclosedwarning}
                {$unreadreports}
                {$pending_joinrequests}
                {$awaitingusers} <!-- BAM -->{$bam_announcements}<!-- /BAM -->

您需要在自定义类中构建代码，并且可以创建所需的所有实例。

如何从我的javascript代码中制作两个倒计时器？
