Javascript implements word count statistics, and javascript implements word count

The word count statistics function is used to add an onKeyup event to textarea. The event reads the content of textarea, obtains the length, and assigns the value to the text node that counts the number of words, one thing to note here is that the addition of onKeypress and onKeydown events can also achieve results, but there are some deficiencies that may cause misunderstandings in some cases. I have tried them all, I feel that using only one onKeyup event is the smartest choice.
