Question

如何在代码中解决此问题？

这很奇怪，因为我无法在代码中找到它，但是Firefox抱怨“ MouseEvent.mozPressure已过时。请改用PointerEvent.pressure。”在控制台中。

是否可以解决此问题？我不知道该怎么做才能解决此问题。

此错误消息出现在jsfiddle，gitHub页面和codepen中。

Answer 1

这是警告，不是错误。看来您的代码仍然可以正常工作。但是要摆脱警告，您可以使用try-catch块。我无法确定您的警告来自何处，因为我没有收到该错误。如果您指定该行，我可以为您添加try-catch。

Answer 2

该错误可能是由其他原因引起的。这只是一个警告，因为它与您的代码无关，所以我不必担心。如果您访问大多数网站，即使在控制台上也有错误消息，这些错误消息不会以任何方式影响您的工作。如果您正在做的一切都正常，那么我就不用担心。祝你好运，这看起来很酷！

Answer 3

Marci回答on another forum时，此警告来自嵌入的YouTube。实际上，只要您在Firefox中访问youtube.com，就会触发该事件。相关代码位于desktop_polymer_inlined_html_polymer_flags_v2.js的第1355行。

不推荐使用MouseEvent.mozPressure。使用PointerEvent.pressure代替
