Attribute explanation:

data-maxsize: the The maximum number of words that the text field can accept. (important)
data-output: If you want to dynamically display the number of words in the text box in real time, this attribute sets the ID of the span or div that displays the number of words. (The color of the word number display will change with the number. Change)
If you do not modify its source file, after adding the js reference, you only need to add the data-maxsize attribute to your text or textarea.
