我不知道触发它的原因，也不了解错误的解释。

Answer 1

您需要使用PHP连接运算符.将字符串与变量连接：

print "<tr class='pointer' onclick=location.href='inventory.php?setID=" . $setid . "&catID=" . $catID "'>"

Answer 2

你的OnClick需要在引号内，变量应该在引号之外。

print("<tr class='pointer' onclick=\"location.href='inventory.php?setID=" . $setid . "&catID=" . $catID . "'>\"");

Answer 3

将您的代码更改为：

 private Map<String, String> eventsForThisCategory;
    ...
    Map<String, String> getEventsForThisCategory() {
        if (eventsForThisCategory == null) {
            Collection<INotificationEventsObj> notificationEvents = notificationEventsIndex.getCategoryNotificationEvents(getCategoryId());
            eventsForThisCategory = new HashMap<String, String>();
            for(INotificationEventsObj notificationEvent : notificationEvents) {
                eventsForThisCategory.put(notificationEvent.getNotificationEventID(), notificationEvent.getNotificationEventName());
            }
            logger.debug("eventsForThisCategory is {}", eventsForThisCategory);
        }
        return eventsForThisCategory;
    }

属性 onlick 的值应该在引号内。
