Firefox中的NS_ERROR_INVALID_POINTER错误是什么？ [英] What is the NS_ERROR_INVALID_POINTER error in Firefox?

问题描述

在Firefox 3.5中测试JavaScript代码时，有时会出现以下错误：

While testing JavaScript code in Firefox 3.5 I sometimes get the following error:

Component returned failure code: 0x80004003 (NS_ERROR_INVALID_POINTER)

我尝试过Google搜索，但我可以找到的是解决其他人代码中特定问题的解决方案（即如果你这样做不同，则不会发生错误）。但是我想要理解的是：什么是那个错误 - 这是什么意思？换句话说，我真的从那个错误中知道什么，我需要猜测什么？

I've tried Googling it, but all I can find are solutions to specific problems in other people's code (ie. "if you do this differently then the error will not occur"). But what I'd like to understand is: what is that error - what does it mean? In other words, what do I really know from that error and what do I need to guess?

推荐答案

不知道具体什么正在调用，错误通常意味着您已经将某些null传递给不需要空值的内容。

Without knowing specifically what you are calling, the error generally means you've passed something null to something that does not expect a null value.
