Article Introduction：jQuery remote verification rules: efficient AJAX form verification Core points The jQuery validation plugin provides a rule called "remote" that allows AJAX requests to be made during the verification process without writing custom rules containing AJAX calls, saving time. The “remote” rule is particularly applicable to validating fields based on server data, such as checking whether a username or email is registered. It sends an AJAX request containing the field value to the server and waits for the server to respond to determine whether the value is valid. Although the "remote" rule only validates one field at a time, it can handle dynamic data or changing fields because it sends AJA every time the field value changes and loses focus.
