Thank you for your valuable reply. ya its correct.for example the form has two fields. I used onBlur event for function call. Entering the cursor on the first field the second field also validated.its why plz help me..
You need onsubmit="return functionname(arguments, ...)" at the "form" tag. Not on each element. Using onblur is actually not a good idea on most cases because only 1 element can be focused at a time. Therefore, onblur may call all other elements once you move from one to the other element.
