Question

在几个小时的愤怒，愤怒，震惊之后，我来到这里 - 也许只是简单的怀疑 - 在我身上发生的事情。

我试图在冗长的脚本中创建最简单的函数 - 通过Id获取元素，然后根据变量更改类的一部分。听起来很容易吗？这是相关的代码：

{literal}
// check to see what kind of ban is this based on the ban_until and ban_at columns in table banlist from return data of /inc/classes/bans.class.php
var banduration = {/literal}{$ban.until - $ban.at}{literal};
if (banduration !== 1 || 0) {
    var bantype = ((banduration < 0 || banduration > 3600) ? "ban" : "warning");
}
// replace all classnames with others in case this is a warning/ban, and END the script before it also changes modnames
if (bantype === "warning" || "ban") {
            document.getElementbyId("modname_message_background").className = "common_background " + bantype + "_background";
            document.getElementById("modname_message_bottomribbon").className = "common_bottomribbon " + bantype + "_bottomribbon";
            document.getElementById("modname_message_letterbox").className = "common_letterbox " + bantype + "_letterbox";
            document.getElementById("modname_message_modname").className = "common_modname " + bantype + "_modname";
            document.getElementById("modname_message_servertime").className = "common_servertime " + bantype + "_servertime";
            document.getElementById("modname_message_signature").className = "common_signature " + bantype + "_signature";
            document.getElementById("modname_message_topribbon").className = "common_topribbon " + bantype + "_topribbon";
            document.getElementById("modname_message_username").className = "common_username " + bantype + "_username";
        }

这是相当不言自明的：这是在Smarty模板中，$ban.until是禁止结束的unix时间，$ban.at是应用它的unix时间，依此类推等等。但是当我运行这个脚本时，它的目的是根据个人主持人排名（稍后但我离题）和消息类型（消息，警告或禁令）来更改禁止消息。当我插入它时，只使用了第一行。激动，我花了两个小时以不同的方式多次重做它，完全无济于事。对自己感到愤怒，我写道：

if (bantype == "warning" || "ban") {
    var list = ["modname_message_background","modname_message_bottomribbon","modname_message_letterbox","modname_message_modname","modname_message_servertime","modname_message_signature","modname_message_topribbon","modname_message_username"];
    var secondlist = ["background","bottomribbon","letterbox","modname","servertime","signature","topribbon","username"];
    for (var i=0;i<list.length;i++) {
    document.getElementById(list[i]).className = "common_" + secondlist[i] + " " + bantype + "_" + secondlist[i];
    }
}
return;

这也不起作用。我不相信 - 被击败，我来到这里，恳求我不得不错过的一个可笑的简单错误，因为只有这么简单的东西才会是如此令人讨厌。

我可以确认变量banduration运行正常（使用alert）。

Answer 1

if (bantype === "warning" || "ban")

不符合您的想法。它相当于：

if ((bantype === "warning") || "ban")

总是如此，因为"ban"不是假的。它应该是：

if (bantype === "warning" || bantype === "ban")

和

if (banduration !== 1 || 0)

应该是：

if (banduration !== 1 && banduration !== 0)

无法更改多个className
