The HTMLEncode function is the necessary step to convert a user name to a legitimate character.
The Requestint function mainly determines whether a user name contains spaces based on the number of valid characters entered.
Call method: Check.asp? Username= username &usernamelength= User name length
Check.asp is generally used for AJAX judgments
