Is it bad to use inline JavaScript event handlers, or is that fine?
使用内联JavaScript事件处理程序是不是很糟糕,还是那么好?
On the page I plan to use it on, I'm only going to use an event handler once, so is it acceptable to use an inline event handler in this case, or shall I write the code for the event handler within <script> tags?
在我计划使用它的页面上,我只会使用一次事件处理程序,所以在这种情况下使用内联事件处理程序是可以接受的,还是应该在

Its bad practice if your concern is readability in your mark-up and maintenance, especially on a larger scale it can get quite messy - also keep in mind the inline JS will never be cached like an external js file would so you do suffer a bit in regards to performance especially if you abuse it
