您输入的电子邮件或密码是不正确的jQuery？ [关闭]

Question

I have a task: I have a log in box with username and password. And if combination of the email and user is incorrect when click the button log in to display text message "The email or password you entered is incorrect." with only jQuery. What do you think is it possible to check something like this in html page with jQuery . I think I need dynamic page and database and I need to use something like PHP ? Thanks for the opinion!

Answer 1

Well you shouldn't ask for opinions here but anyway if your useres are saved in a, lets say mysql database, you need defenitly a server side language (php...). Javascript and jquery are client side languages. That would mean that you need to send every visitor a list of every user, to check for a correct login.
