为了避免验证，请使用HTML5中的formnovalidate属性。在该示例中，禁用了第二个按钮的验证：
<!DOCTYPE html> <html> <head> <title>HTML formnovalidate attribute</title> </head> <body> <form action = "new.php" method = "get"> Rank <input type = "number" name = "rank"><br> <input type = "submit" value = "Submit"><br> <input type = "submit" formnovalidate = "formnovalidate" value = "Submit with no validation"> </form> </body> </html>
