virtualbox中的webstorm许可证,ubuntu 14.04.1(webstorm license in virtualbox, ubuntu 14.04.1)

我在Oracle VirtualBox上安装了webstorm 9并得到以下错误:

-VirtualBox:~/Downloads/WebStorm-139.252/bin$ ./webstorm.sh

  • 我用WebStorm 8试过这个并遇到了同样的问题。
  • 我在VMWare上尝试了同样的功能,在这里我没有遇到任何问题。

任何提示?

  • I have tried this with WebStorm 8 and got the same problem.
  • I have tried this with the same on VMWare, here I had no problems.

Any hint?

最满意答案

事件是完全不同的目的。 使用keyupkeydown来识别物理键和keypress以识别输入的字符。 两者是不同事件的根本不同的任务; 不要试图混合两者。 特别是, keypress事件的keyCode通常是多余的,不应该被使用(除了在较旧的IE中,但是有关更多信息,请参阅下面的链接文档); 对于可打印的按键,它通常与whichcharCode相同,尽管浏览器之间有一些差异。

Jan Wolter关于事件已经链接到另一个答案的文章是关于这个主题的最后一个字,并且描述了每种类型的关键事件和每个浏览器对每个不同的属性返回的表。


The events are for completely different purposes. Use keyup and keydown for identifying physical keys and keypress for identifying typed characters. The two are fundamentally different tasks with different events; don't try to mix the two. In particular, keyCode on keypress events is usually redundant and shouldn't be used (except in older IE, but see the linked document below for more on that); for printable keypresses it's usually the same as which and charCode, although there is some variation between browsers.

Jan Wolter's article on key events, already linked to in another answer, is the definitive word on this subject for me and has tables describing what each of the different properties returns for each type of key event and each browser.
