MouseEvent.mozPressure已弃用。请改用PointerEvent.pressure

Question

如何在代码中修复此问题？

这很奇怪，因为我在代码中找不到这一点，但火狐抱怨说"MouseEvent.mozPressure已被弃用，请改用PointerEvent.pressure。“在控制台中。

有没有办法解决这个问题？我不知道我需要做些什么来解决这个问题。

此错误消息出现在jsfiddle、gitHub页面、codepen中。

Answer 1

错误可能来自其他原因。这只是一个警告，因为它与您的代码无关，所以我不会担心它。如果你访问大多数网站，即使他们在控制台中有错误消息，也不会以任何方式影响你正在做的事情。如果你所做的一切都是有效的，我不会担心。祝你好运，这看起来是个很酷的项目！

Answer 2

这是一个警告，而不是一个错误。看起来你的代码仍然有效...但是，为了消除警告，您可以使用try-catch块。我不知道你的警告是从哪里来的，因为我不明白这个错误。如果您指定这一行，我可以为您添加try-catch。

Answer 3

正如Marci回答on another forum时所说的，这个警告来自YouTube embed。当你在火狐中访问youtube.com时，它实际上就会被触发。相关代码在desktop_polymer_inlined_html_polymer_flags_v2.js的1355行。
