Question

Trying to check if a text box is visible then the user should enter a value in it.
the below piece doesn’t work.

if ($(':text.TextNormalJQH').is(':visible').filter('[value=""]').length > 0) 
  {
     alert (" Entering data for all the visbile textboxes is mandatory");
  }

Thanks in advance

You’re really close. Just change it to:

if ($(':text.TextNormalJQH:visible').filter('[value=""]').length > 0) {
  alert (" Entering data for all the visbile textboxes is mandatory");
}

Or, you could do this:

if ($(':text.TextNormalJQH:visible').is('[value=""]')) {
  alert (" Entering data for all the visbile textboxes is mandatory");
}

The reason you’re having problems is your use of .is(). Basically, it returns true if any of the matched items pass it, filter returns the matched items. http://api.jquery.com/is/
