使用 doucment.write 但我不知道如何修改它

write","document

我尝试了一些在线工具对其进行解码，但它们并没有帮助我完全解码它，从部分解码部分我看到了 document.write，我认为这已经写完了我的整个页面，请原谅我的英文

谢谢你

标签： javascripthexshopifydecode

解决方案

document.write(...)将始终覆盖您的文档。相反，您可以使用：

document.body.append(...);

这将在不覆盖的情况下做同样的事情。然而，大多数时候使用类似的东西更有意义document.getElementById("idOfElement").append(...)
