Usage of AJAX in an alert box

Question

I have a javascript alert asking the user to insert a password. When user presses button, I will do an AJAX call to check the password. This could generate another alert with the response (if it was accepted or not), but I wonder if it is possible to have the AJAX response change the text of my first alert? Is it even possible to override the alert button's default not to close itself when clicking "okay"?

Answer 1

I think generally you should try and minimize the use of alerts in your web application. They are very obtrusive and annoying. Generally people just update the DOM to display user information. An alert is for something more unique and important than somebody just mistyping their password.

EDIT:

As other people are pointing out, you should use modal dialogs instead to have behavior as you specify.

Answer 2

I'm quite sure you can't do that since the way the alert is constructed and displayed is different in each browser (just look at mobile browsers). I think you'll safeguard your sanity longer if instead you use modal dialogs.

Answer 3

作为一个阻塞函数， alert()本身就是可憎的，因此，它会阻止您尝试执行的操作。
