【问题描述】:
问题是我无法点击网站上的标签,如果我点击标签;它显示
未捕获的类型错误:无法设置 null 的属性(设置“值”)。
有没有办法解决这个问题?另外,我是初学者,我不知道如何解决这个问题。代码是用 PHP 和 Javascript 编写的。

以上代码是 Javascript 代码。错误在 Javascript 中显示以及如何解决?
【问题讨论】:
-
哪行代码会抛出错误?该消息将指向它。作为一个初学者,我猜你没有写所有这些代码?仅供参考,那里有更简单/更新的选项卡实现,它们不需要您维护自己的代码,不抛出错误,也不依赖诸如 eval() 之类的安全风险函数.
-
function DisplayTab(tabname,tabid) { document.getElementById(tabid).value = tabname; // 这是 $str_tab document.lotmgt.submit(); }
-
此外,这段代码试图将自己设置为 Internet Explorer 5(1999 年发布,2005 年退役)的模式,所以我认为这可以让您了解它的年龄!它可能非常不适合现代浏览器。扔掉它,不值得修理。
-
它说代码出现未捕获类型错误:无法设置 null 属性(设置“值”)。
