在我打算使用它的页面上,我只打算使用一个事件处理程序,所以在这种情况下使用内联事件处理程序是可以接受的,或者我应该在< script>中写入事件处理程序的代码。标签?
如果您的关注是您的标记和维护的可读性,那么它的不良做法,特别是在更大的范围内相当凌乱 - 还要记住,内联JS永远不会像外部js文件一样被缓存,所以你对性能有一定的影响,特别是如果你滥用它

Is it bad to use inline JavaScript event handlers, or is that fine?
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?
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
