I am doing an updation. So I have set value from database to a text box in time format like HH:MM
00:00 if I enter 8:00//it should show error if I enter 08:0//it should show error
How can I perform this???. Entering this value in a text box. Ajax code also acceptable. it is a web application form and it is in a 24 hours format also.
