These use cases show how necessary are the " Alerts" or " Popups" in Web Applications. Pressing the OK button on the alert box takes me back to the form, and the form does not submit until I have filled everything " required".

At times, I forget to check the terms and conditions box, and I get the same as a notification via a popup-up alert. A lot of the times, when we are filling in a form and press the submit button, an alert pops up, telling me, " Contact Number is Required".
