jim is creating a form with validation. what are the two validation modes available to him?
checks if the data the user
only checks if a user has entered data in a mandatory field, whereas
entered is correct or valid.

i) To check for mandatory field:

This requires that particular control is empty or not. If empty then user should be prompted to enter answer. In Javascript,

if document.getelementbyID(“control_name”) = “”

Msgbox “Enter the value”

ii) To chec whether the entered value is valid or not

if document.getelementbyID(“control_name”) = “”

Msgbox “Please Enter the value. The field is mandatory”

else document.getElementbyID(“Control_name”)!= “Valid value”

Msgbox “Please enter a valid value”

The else part check whether the entered value is the expected value. If “yes” then it will continue to next line of code. If “not” then a message box pops up to inform the user that he/she needs to enter a valid value

it would be a. excessive network collisions or d. slow connectivity between devices those would be my answer.
