Later, when I was wandering around on the Internet, I suddenly found a better jquery plugin with character limit for text boxes. It is simple and easy to use. >Copy code

Text box word limit function jquery plug-in_jquery The code is as follows:

< head> About the character limit function of the text box

< ;p>Enter your hobbies (<50 characters)




< /div>

Enter your postal code (<6 characters)







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.
About dynamically setting the maximum value
Use the setformfieldsize method:
setformfieldsize($field, maxsize, outputfieldid)
Attribute explanation:
$field: is the JQuery object of the restricted text box (reference Jquery document).
maxsize: Same as data-maxsize, the maximum number of words that the text field can accept.
outputfieldid: Same as data-output.
Example:
